application; (real-world problems, dependent on topic, etc.)*
Content Instruction Plan
Day 1- Probability and Odds Prior knowledge: Ability to reduce fractions. Basic mathematics
operations. The lesson will begin with me showing students a spinner with 4 even sections.
Three sections are red and the other is blue. Next, I�ll ask the students the percent chance of
landing on blue. On red? And the probability of not landing on red. Through discussion we will
conclude that: Probability = # of favored outcomes / # of possible outcomes. Using a die. Find
the probability of rolling a 3? Find the probability of rolling an odd? Spinner. We want blue. How
many favorable outcomes are possible? How many unfavorable outcomes are possible? What
are the odds of landing on blue? What are the odds of landing on red? Through discussion we
will conclude that: Odds = # of favorable outcomes / # of unfavorable outcomes. Discussion
questions: How are odds and probability different? How are they related? Given the probability
that an event occurs, determine the probability that the event will not occur. Ex. 1 70% Ex. 2
0.35 Ex. 3 2/7 Find the probability and odds of randomly choosing a green marble from the bag
of marbles described. Ex. 4 3 green and 6 red Ex. 5 7 green and 2 red
Day 2- Probability and Odds Prior knowledge: Ability to reduce fractions. Basic mathematics
operations. Review and practice from day 1. How do you represent probability? How do you
represent odds? Given probability, find probability against. Ex. 1 63% Ex. 2 9/11 Ex. 3 0.51 Ex. 4
The weather man says there is a 30% chance of rain tomorrow. What are the odds that it will
rain tomorrow? Ex. 5 25 Students were asked what their favorite meal is. What is the probability
that a randomly chosen student chose pizza? What are the odds that a randomly chosen student
chose hamburgers? What are the odds that a randomly chosen student did not choose pizza?
Day 3- Independent and Dependent Events Prior knowledge: Ability to solve for unknown
variables. Basic mathematics operations. What is independent? What is dependent? Through
discussion we will develop in formal definitions. Using poker chips, 2 blue, 3 red, and 5 white, in
a bag. I�ll pull out one chip replace it and draw another. Is this dependent or independent?
Then I�ll pull out one chip not replace it and draw another. Is this dependent or independent?
Then, as a class we will determine the probability of the independent event of pulling a red chip,
replacing it, and drawing a white chip. Then, as a class we will determine the probability of the
dependent event of pulling a red chip, not replacing it, and drawing a white chip. Why are they
different? Repeat a few times. Using dice. Is rolling dice two times a dependent event or
independent event? What is the probability of rolling a 1 and then rolling a 2? Repeat a few
times with other examples. Dependent or Independent? Ex. 1 You are beginning a 500-piece
puzzle. The first piece you randomly choose is a corner. The next piece you randomly choose is a
corner. Ex. 2 You spin a spinner on a board game and it lands on �spin again.� On the
second spin you land on �spin again.� Given probabilities find the missing probability.
Events are independent. Events are Dependent. Ex. 3 P(A)=0.3 Ex. 4 P(A)=1/6 Ex. 5 P(A)=0.6 Ex. 6
P(A)=0.9 P(B)=0.1 P(B)=2/5 P(B given A)=0.4 P(B given A)=? P(A and B)= ? P(A and B)= ? P(A and
B)= ? P(A and B)=0.09 Ex. 7 A jar contains 5 oatmeal cookies, 6 sugar cookies, 8 frosted cookies,
and 9 chocolate cookies. You choose a cookie randomly, keep it and randomly choose another.
What is the probability that you choose a frosted cookie, then a chocolate cookie?
Day 4- Independent and Dependent Events Prior knowledge: Ability to solve for unknown
variables. Basic mathematics operations. Review and more practice from day 3. When one event
affects the outcome of another, the two events are ____________. When one event does not
affect the outcome of another, the two events are ____________. Find the missing probability.
Ex. 1 P(A)=0.2 Ex. 2 P(A)= ? P(B)=0.9 P(B)=0.5 P(A and B)= ? P(A and B)=0.3 Ex. 3 Each day, the
person who gets the lucky tray at lunch gets a free snack. 127 people buy lunch on Wednesday
and 134 buy lunch on Thursday. What is the probability that you win both days?
Day 5- Hands-on Probability and Odds Prior knowledge- Understanding of probability and odds,
basic math operations. Students will be put into pairs. Students will complete 3 activities. CardsStudents will cut a piece of paper into 8 equal sections. They will number them 1-8. One person
in the group is represented by the card 1 and the other member is represented by the card 2.
Students will then shuffle the cards and choose 2 randomly and record the results. Then
students will repeat for a total of 10 trials. Next, we will compile the class results. Then we will
calculate the experimental probability. And then the actual probability. Compare the two. If we
did 100 trials each would the experimental probability be more accurate? Explain why? Poker
chips- Each pair receives a bag with 10 random red, white, and blue poker chips inside. Don�t
look inside. Students will then record the results of 50 trials of choosing a random poker chip,
replacing it and randomly drawing another. Students will then calculate the experimental
probability for each color. Then using this information, students will guess the number of each
color contained in the bag. Next, students will check their guess and find the actual probabilities.
Dice- Now the pairs will be split into 3 groups. Each pair will make a chart for favorable
outcomes over unfavorable outcomes. One group is trying for a 1 or 2, another is trying for a 3,
and the other is trying for an odd number. After many trials are run the groups compile their
results and compare the experimental odds with the actual odds they calculate.
Day 6- Samples and Data Analysis Prior knowledge: Understanding biased and unbiased. What is
population? Develop an informal definition through discussion. What is a sample? Develop an
informal definition through discussion. What is a random? Develop an informal definition
through discussion. What is a biased? Develop an informal definition through discussion. Next
we will relate these definitions to complete the following examples. Ex. 1 The student council
wants students to help decide on a theme for a costume dance. Students can choose one of the
council�s three theme ideas: movies, famous historical figures, sports and games. Surveying
all the students would take too long, so a sample will be surveyed. Tell whether the survey
method could produce biased results. Explain. a. Survey members of the movie club. b. Survey
students as they enter the school. c. Survey students on the football team. Ex. 2 Tell whether
the question could produce biased results. Explain. a. Do you support the unfair policy of
requiring students to do a time-consuming community project? b. Do you like our new apple-nut
yogurt flavor, now on sale in stores everywhere?
Day 7- Test Review Day 8- Test
6. Differentiated Instruction: List specific activities, strategies or techniques used to provide
instruction for diverse students, including ESOL students. Please list this information here even if
you wrote it into the plans above. *
2 students are learning disabled 1 student is classified as homeless because they are sharing
other�s home due to hardships Modifications for these students include preferential seating,
shortened assignments, extended time for tests and assignments, and allowed to retake failed tests.
UNIT PLAN: ANALYSIS AND REFLECTION
iv. Analysis of student learning
1. Analyze the effectiveness of your instruction using the Pre/Post test. Explain the results of your
graph. What conclusions can you reach about your students and your teaching?*
The graph shows the results of the Pre-test in blue alongside the results of the Post-test in red. The
grades for the Pre-test were 8 D’s and 53 F’s. After the unit was taught, the scores on the Post-test
were 18 A’s, 13 B’s, 19 C’s, 7 D’s, and 2 F’s. All students improved from before the unit to after the
unit as shown by Pre- and Post-test scores. Students also displayed learning gains by the
observations I made of the continuous assessment of practice assignments and questioning.
Learning gains were also observed as student applied their knowledge of Probability and Odds to
the hands-on activities that required this knowledge to complete. Through observation and
reviewing of the Post-Test scores students showed significant learning gains as a result of the unit
being taught.

v. Reflection and self-assessment
1. Reflect on the effectiveness of your Unit Plan. Why or why not was your plan effective? *
I feel the plan was effective because of the observed and quantitative learning gains that the
students displayed. I was well prepared for each day with the right materials and knowledge of what
is being taught. I feel that my preparedness enhanced the effectiveness of the lesson. All of the
formative assessment materials and activities were appropriate in providing practice for students.
This unit, I feel, was clearer in describing the flow of the lesson as it allows for student participation
than my first unit. This unit also included better prepared outlines of modifications for differentiated
instruction that allowed me to implement them more effectively. I also feel that the Post-Test
assessment was better prepared for this unit and allowed for the test to effectively measure student
learning gains.
2. Reflect on your teaching effectiveness. What are your teaching strengths? What can you change
to enhance student learning? What would you do differently? *
I feel that the teaching was effective because of the observed and quantitative improvements in
students’ skills from the Pre-test to the Post-test. After the unit, students understand the necessary
vocabulary and possess the skills needed to evaluate probability, odds, and other data analysis
problems. I feel that my teaching strengths include a mastery of the content, sufficient
preparedness, and the ability to answer questions effectively. I feel that my understanding of
mathematics is more than sufficient for teaching at this level. I also feel that my preparation before
teaching the unit makes my teaching effective because I am able to focus more on responding to
student needs rather than scrambling for what to do next. My effectiveness at answering students’
questions is effective because I can explain again or explain in a different way so that students can
understand. Time management is an area that I have struggled with for some time. I feel that I have
improved my time management of the classroom as I have become more familiar with the settings. I
feel that this area could still improve, but has improved greatly since the first unit. To improve my
time management I will observe other teachers to learn some of the ways they manage time.
