1 Education 50G3 Module 10 – Research Report Abstract: This study examined the effectiveness of introducing the game of cribbage to a group of Grade 10 Mathematics Essentials students as a non-traditional approach of decreasing their dependence on calculators when performing basic mathematical computations such as addition, subtraction and estimation. There were 21 students involved in this project, 12 of which required adaptations such as a reduced workload, preference seating, cues for staying on task and marking spontaneous writing. Student pre-testing was preformed at the beginning of the course along with both student and teacher survey/questionnaires. As the study moved forward, progress was monitored through a number of cribbage worksheets that were administered on a weekly basis. At the end of the study follow-up testing along with second student questionnaire was conducted to determine the effectiveness of the project. The results of the test suggested a positive increase in both addition and subtraction skills and the questionnaire suggested that the cribbage method was enjoyable. Nature of the Problem: Many lunchtime conversations with math colleagues focus on the concern over student dependence on the calculator and/or their lack of simple mental math skills. For many higher-level classes, the calculator is used so often in daily lessons that some of those skills have become “rusty”. Although it is important for these students to undergo some math exercises to clean out the mental math cobwebs, that the majority of them still have the skills. Unfortunately there are many groups of students who do not have those mental math skills. The Math 10 Essentials course is designed to support those students who have struggled with mathematics for most, if not all, of their school career. Many of these students have external issues that make learning difficult and the peer pressures of high school only compounds the problem. I’ve worked with approximately 8 groups of Math 10 Essential students and I am continually surprised at how weak their mental math skills 2 are. When I mention mental math skills, many teachers think of multiplication facts. The truth is that the majority of students I work with in this class have difficulty even adding numbers that have answers in the double digits. Subtraction provides an even greater problem. Improving mental math skills is an important part of the Math 10E curriculum. Many traditional approaches to increase mental math skills such as the “mad math minute”, flash cards, and even power point lessons have been tried with varying degrees of success. The problem with the traditional approach is that the daily practice soon looses its bite as many in the class do not take it seriously or are not motivated enough to try and improve their previous score. Therefore, it is important for teachers of the essentials level program to find non-traditional methods of teaching mental math skills that might hook essentials students and provide them with an interesting yet effective approach to improving skills. Literature Review If I had $7 in my pocket and found a five-dollar bill on the ground, how much money would I have in total? For many students in my Math 10 Essentials class, this type of basic addition question can cause an automatic trigger response. They either begin counting on their fingers or reach for a calculator. Very few will mentally calculate the answer. If I ask them to solve the problem without the aid of their fingers or the calculator, I may get some random guessing occurring or, in some cases, refusal to answer. This is a typical response when their fear of mathematics overpowers their ability in mathematics. For many, aids such as 3 the calculator provide them with the edge necessary to navigate through math class without having to deal with the hurdles that can arise from mental mathematics. To deal with these issues, mental math is one of the outcomes in the Math 10 Essentials curriculum. It is important to establish reasons why mental math and estimation are important skills to develop and master. This has been my math hurdle for a number of years. It is one thing to state that we need to improve mental math skills, but convincing students, whom many of which have given up on math, that they need to practice doing calculations in their head, is quite another. There are many traditional approaches to improving mental math skills that can be effective with some groups of students. Unfortunately, I have not had any success with these methods when implementing them with the essential-level students. It is my hope that this literature review will help bring some focus to my research question and perhaps provide some strategies to implement and pitfalls to avoid. This review is based on the following research question: Can using a non-traditional approach of teaching my Math 10 Essentials class the game of cribbage, increase their mental math skills and allow them to work through the addition, subtraction and estimation modules without the aid of a calculator? Gaming and Mathematics Games provide opportunities to explore basic number concepts such as counting, quantity and one-to-one correspondence along with higher levels of mathematical reasoning such 4 as combinations, patterns and place value (Olson, 2007). For the past two decades, the National Council of Teachers of Mathematics (NCTM) has been pushing the importance of manipulatives as way of having students visualize number concepts and provide a concrete reference to difficult mathematical operations. It can be argued that games are a form manipulatives as they help students solidify mathematical operations. Unlike traditional manipulatives such as algebra-tiles, games have the added bonus of disguising their mathematical relevance. It is important to note that even though students may not immediately recognize the connection between the game and a mathematical concept, the importance or benefit of the manipulative is not lost. Baker (1999) reasoned that the content-centered use of manipulatives could yield positive results regardless of how immediate the connection is made. My essential students are more apt to continue using the manipulative if they perceive it to be a game and not a teaching tool. Gaming and Students Games can provide students with an opportunity to explore mathematical concepts in an engaging and non-threatening environment (Olson, 2007). Students in my Math 10 Essentials class have experienced limited success in mathematics and have come to accept that their number sense and mathematical ability have not developed beyond basic elementary operations. While each student can provide a number of unique reasons for their weaknesses in math, the common theme that unites them all is that they have developed an aversion for mathematics. Baker (1999) states that games can present an alternative approach for students that may have become disenchanted with traditional approaches to the mathematical curriculum. Games have the potential to be a very powerful tool for teachers especially when dealing with students at the foundation (or 5 essentials) level. Students are more likely to internalize and remember material when they are actively engaged in the learning process (Bonwell & Sutherland, 1996). Games have the distinction of giving the appearance that they are not connected to educational goals and outcomes. For most of us, gaming was introduced before schooling and thus we are able to justify their separation. Even games that are solely educationally based can pass as a simple fun activity. An added bonus for teachers is that ideas and gaming rules that are obvious to adults can often create mathematical discussions in the classroom (Olson. 2007) The Importance of Mental Math O’Nan (2003) argues that “students who are equipped with a greater variety of mental computation strategies will solve problems more quickly and accurately because they can choose the strategy that will be most effective for the given problem.”(p. 10.) In my experience, students who have strong mental computational skills also develop a comfort level for mathematics and are less likely to form barriers when more difficult concepts are introduced. Yang (2002) suggests that number sense is a valuable skill that leads to improved efficiency in solving mathematical equations. If number sense is the key to improving problem solving then Beishuizen, Van Putten, and Van Mulken (1997) insist that the only way to increase number sense is to place an increased emphasis on mental mathematics. Another important reason for focusing on mental mathematics is the role it plays in the curriculum. The Nova Scotia curriculum document for Math 10 Essentials lists the following mental math outcomes: 6 know the double facts in addition; their extension to 2, 3 and 4 digits; their 1 connections to subtraction, multiplication by 2 and by , division by 2 and 2 multiplication by 50% know the addition and subtraction facts and extend them to 2, 3, and 4 digit numbers estimate appropriate sums, differences, products and quotients mentally calculate 1%, 10%, 15% and 50% of quantities that are compatible with those percents estimate percents of quantities Why Cribbage This proved to be the most difficult part of my literature review. Although I have a strong sense for the potential role that cribbage can play in the essentials classroom, finding articles to either defend or negate my feelings proved difficult. As Baker (1999) indicated in his paper, “An exhaustive review of the literature, both electronic and text-based, led to the sure conclusion that there are no papers or reports published in the past couple of years that relate the standard deck of playing cards to the standard mathematics classroom.” (p. 4) I was able to locate one NCTM article that was written in April 2005 that directly ties in the benefit of cribbage with mathematical thinking. Markel (2005) suggests that cribbage hands are an excellent application of mathematical reasoning and goes on to talk about how surprising their omission in the classroom is. It is rare to find any discussion of cribbage in modern math textbooks especially when compared to how often poker is used in probability and statistics. 7 My goal is to teach my essentials class how to play an entire game of cribbage. This would include teaching them the ability to count the total points in their hand using mental math. Markel (2005) points out that for younger students, such as junior high students, computing the point value of a hand is a good combinatorial problem. A more difficult problem is determining which total points are possible and looking at the different ways of obtaining these scores. Another aspect of cribbage problems is that there are often several ways, or several orders in which the counting may be done. Teachers can use cribbage hands to: Evaluate the points of randomly chosen hands List crib hands that can produce a certain points total. Count the number of ways a given configuration can occur Find all configurations that give a particular point value Learn to play the game. Remember its fun and a good teacher of mathematical thinking. Games are fun and create an environment for developing mathematical reasoning. All the articles that I have read provide overwhelming support for the use of games in the classroom to enhance the mathematical experience and to provide students, especially those that have become disillusioned, a fun way to develop computational skills. They also outlined the importance of providing repeated opportunities to play games so that mathematical ideas will emerge and pattern recognition can occur. As students begin to understand the intricacies of the game, they will begin to form mathematical relationships and strategies for winning the game. They will explore mathematical ideas and prioritize the importance of these ideas based on how successfully they can implement them. This 8 is an important part of developing math skills but one that takes time and patience. Many articles also point out that it is important to choose appropriate games. Some games encourage children to memorize facts, such as multiplication flash cards. These games do not engage children for long as they either quickly memorize the facts or realize that they have difficulty in memorizing and turn off completely. Another pitfall is that teachers may use games that encourage recall speed. While this may be the desired outcome of the game, it is important to stress that being “smart” in math does not necessarily mean getting the answer the quickest. We need to place value on the process of thinking. Through playing and analyzing games, students gain computational reasoning skills. Discussing relationships and strategies for winning the game help develop number sense and strengthen ones mathematical confidence. Cribbage can provide students with an interactive experience that allows them to develop addition, subtraction and estimation skills and more importantly shows them that these mathematical methods can be valuable. Although card games are not the only source of teaching mathematics, their use in the classroom is justifiable. Data Collection A series of lesson plans were developed that break the game of cribbage down to manageable pieces for Math 10 Essential students. (See Appendix) These worksheets slowly introduce the many aspects of scoring and working with the cribbage board. 9 To acquire some baseline data for my action research problem I decided to use both questionnaires and pre-tests. My focus group for the action research is my second semester Math 10 Essentials class. There are 21 students in this class and I was able to use this group to obtain some of my baseline data. I also surveyed 5 teachers that work with students in this level of mathematics. All data was collected during the first week of February 2008. Math 10 Essentials Student Questionnaire On the first day of class I always hand out a questionnaire to my students that focuses on their feelings about mathematics. This year, to coincide with my action research, I adapted the questionnaire to include both questions about their feeling for mathematics and their feelings about the use and/or their dependence on the calculator. I asked the students to read the statements and make an honest choice based on their overall feeling. To encourage truthful responses, I told the students that the survey was used to provide me with a general overview of the whole class and it was not necessary for them to include their name on the sheet. Directions: Students were asked to read the statements and to check either AGREE or DISAGREE depending on their feelings. Participation: 21 Students % Of Students that Agree % Of Students that Disagree I enjoy seeing how rapidly and accurately I can work math problems. 48% 52% I think about mathematics problems outside of school and like to work them out. 19% 81% I don’t feel sure of myself in mathematics unless I use a calculator. 81% 19% 10 I prefer to do math with a calculator even if the questions involve simple addition. 76% 24% I am faster at solving math problems if I use a calculator 86% 14% I feel more confident with my answer if I used a calculator to find it. 86% 14% When I go shopping, I am able to estimate what my bill will be with tax included. 48% 52% I find it easier to add two numbers than to subtract two numbers. 81% 19% I have always been afraid of math. 57% 43% The results from the student questionnaire, while worrisome, are not surprising. Students lack confidence in their mathematical ability when they are asked to perform tasks without the aide of a calculator. Questions 3-6 all focused on the anxiety that students experience in mathematics when dealing with topics that we assume they have mastered in elementary school. There is a clear indication from this survey that students have developed a calculator comfort zone that will continue to reduce their ability to perform simple mathematical computations without some apprehension. It is also evident that I need to focus more on subtraction skills. This also became apparent through the pre-tests. Math 10 Essentials Teacher Questionnaire I felt that it was important to survey teachers that work with students who are working the essentials level of mathematics. Unfortunately, there are not many Math Essentials teachers in our school. Thus, in order to get a larger sample, I surveyed Math 10 Essentials and Math 10 Foundations teachers. Both of these levels encounter the same hurdles when it comes to mental mathematics. 11 Directions: Teachers were asked to read the statements and to check either AGREE or DISAGREE depending on their feelings. Participation: 5 Teachers I find that my students depend on the calculator to help them solve basic math questions (addition, subtraction, estimation) I feel that my students loose confidence when they are asked to solve a math problem without a calculator Students often use estimation to determine if their final answer is appropriate Students would do just as well on a basic addition/subtraction test if they did not use a calculator Students enjoy traditional methods for improving mental math skills (i.e. Mad Minutes, Flash Cards, Memorizing etc.) % Of Teachers that Agree % Of Teachers that Disagree 100% 0% 100% 0% 0% 100% 40% 60% 40% 60% Students need to improve their mental math skills especially skills involving addition, 100% 0% subtraction and estimation. The results from the teacher questionnaire seem very one sided. It is very evident that teachers feel students have a heavy dependence on calculators and that it is very important to sharpen their mental math skills. There was some discrepancy when it came to an approach to improve the math skills. Although I have not had much success with traditional methods for mental math, 40% of the teachers interviewed feel that students still enjoy those methods. Perhaps as part of my research, I need to inquire further into the traditional methods that these teachers use. Math 10 Essentials Pre-Tests (4 different tests were administered) 12 I knew that pretests would provide an important piece of evidence for my action research but I did not want to base all my conclusions on one test. I decided to administer 4 different tests to my students. One the first day of class (Wednesday February 6, 2008) I gave my students a 25-question basic addition test. They had to complete the test without the aide of a calculator but there was no time restrictions placed on them. They could take as long as they wanted. When they completed this test, I handed them a 25question basic subtraction test. Again, they had to complete the test without the aide of a calculator but they could take as much time as they needed. The reason for administering the no time limit tests is that I wanted to assess whether or not they had the basic skills. The goal of mental math strategies is to sharpen addition and subtraction skills not to create these skills. Although students didn’t have a calculator they had enough time to fall back on some other aides such as using their fingers for counting. On the second day of classes (Thursday February 7, 2008) I handed out an addition test and a subtraction test but this time they had to complete the 25 questions in a set amount of time. From the previous class, I knew that they had the necessary addition and subtraction skills but now I wanted to create an environment where they had to complete the problems mentally instead of relying on their fingers or other tools. Directions: Students were given 4 tests .An addition test and a subtraction test with no time limit and an addition test and subtraction test with a time limit. Test: Each test consisted of 25 questions involving 1 - 2 digit addition and subtraction. Participation: 21 Students 13 Class Average Addition Test – No Time Limit 98% Subtraction Test – No Time Limit 88% Addition Test – Time Limit 65% Subtraction Test – Time Limit 20% When students were given as much time as they needed to complete the tests, their overall class averages indicate that their 1-2 digit addition and subtraction skills are quite strong. I did observe many students using their fingers to count and/or making tick marks on the paper to help them count. When the time limit was introduced, the averages dropped significantly. One reason for this drop is that many of the students that relied on finger counting could not complete the test in the given amount of time. Although they were solving the problems without a calculator, they were not necessarily using mental math to solve the problems. It is also very clear that while students are fairly consistent when it comes to basic addition and subtraction skills, there is a large discrepancy between their ability to apply mental subtraction skills and mental addition skills. Math 10 Essentials Post-Tests (4 different tests were administered) As a way to measure the effectiveness of the cribbage game, I administered 4 tests that were similar in size and difficulty to the pre-tests that were given during the baseline data collection at the beginning of the study. An addition test and subtraction test were first 14 written without a time limit and then similar tests were written under a 1-minute time restraint. Directions: Students were given 4 tests .An addition test and a subtraction test with no time limit and an addition test and subtraction test with a time limit. Test: Each test consisted of 25 questions involving 1 - 2 digit addition and subtraction. Participation: 21 Students Class Average Addition Test – No Time Limit 98% Subtraction Test – No Time Limit 85% Addition Test – Time Limit 99% Subtraction Test – Time Limit 68% Results The results of the testing provided positive evidence that the Math 10 Essentials students increased their addition and subtraction skills without the aide of a calculator. Although there was little increase in their average scores on the “Addition Test – No Time Limit”, and the “Subtraction Test – No Time Limit”, results from the other 2 tests showed significant increases. Pre-Test Post-Test 98% 98% Addition Test – No Time Limit Change 0% 15 Subtraction Test – No Time Limit 88% 92% 65% 99% 20% 68% Addition Test – Time Limit Subtraction Test – Time Limit 4% increase 34% increase 48% increase The “No Time Limit” pre-tests show that students have the skills necessary to add and subtract 1-2 digit numbers. Therefore it is not surprising that these scores remained consistent during post testing. The “Time Limit” tests challenge students to use mental math skills without counting aides such as fingers. The fact that there was such a drastic increase in the scores on both the addition and subtraction post tests seems to suggest that students have acquired some exercises that sharpened their mental math skills. I am convinced that these positive results are directly related to the introduction of the cribbage game over the past two months. Unfortunately, do to my current teaching load, I was unable to bring a control group into this study which would allow me to compare groups who received cribbage training with those who did not receive the training. If one was to conduct further research into this topic, I would certainly suggest working with two classes so that a better comparison of results could be obtained. That being said, I believe there is enough evidence in this study to suggest that the non-traditional approach to increasing mental math skills warrants further investigations. It is my hope to create a small handbook on introducing students to the game of cribbage. 16 I would like to make the worksheets available to other teachers who a searching for an alternative method of increasing mental math skills in the classroom. The cribbage boards can be purchased for a small fee and an entire classroom set, along with an appropriate number of playing card decks can be purchased for under $50. 17 Appendix Learning Cribbage Worksheet #1 1. Scoring “15’s” is one of the main objectives in Cribbage. To obtain “15” you simply have to be able to determine which cards in your hand add up to fifteen. If this was your hand, how many ways could you make different 15’s ? 9D + 3C + 3D = 15 9D + 3C + 3S = 15 9D + 3D + 3S = 15 Each time you make 15, it is worth 2 points. This hand has 6 points in “15’s” How many “15’s” can you make from each of the given hands?
