Content: 6.6A Process: 6.11B Cognitive Level: Understand – students have to choose the angle that can be classified as obtuse and greater than 88.5 Analysis of Distracters Correct Regional Campus/ District Data Answer Data *A/F 85% Correct B/G 6% Greater than 88.5 but not obtuse C/H 5% Greater than 88.5 but not obtuse D/J 3% Not greater than 88.5 or obtuse Instructional Implications: Students in Region 10 were successful for the most part on this question. Students need to be able to classify angles with more than one characteristic. Vocabulary is important (obtuse, acute right). Giving students characteristics and having them write (or show with their hands, arms or bodies) is a great open-ended exercise. Also giving students an angle and having them list and discuss characteristics as a group is also important.

Assist them in understanding the context of the problem by providing visual representations or having students create visual representations. Students need to be able to manipulate the equation given length, width, height, volume or a combination. Students need to work both ways with rules and tables. Given a table, find the rule and given a rule, find a table. Provide opportunities for students to read and interpret information from tables. Provide opportunities for students to build input-output tables and explain the relationships in terms of input-output. Explaining the relationship in terms of input-output is crucial – have them use the words given in their explanation “the volume (128) divided by height (2) will equal length times width”. Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 2014 Grade 6 Mathematics STAAR Reporting Category 1: Numbers, Operations and Quantitative Reasoning Question 6 6.2E (Readiness) The student is expected to use order of operations to simplify whole number expressions (without exponents) in problem solving situations Dual Coding: 6.11A The student is expected to identify and apply mathematics to everyday experiences, to activities in and outside of school, with other disciplines, and with other mathematical topics; Vocabulary: Borrowed, another, equal payments, the rest, repaid, expression When Taught?

Instead took 92-12 then added 16 and divided the sum by 4 Correct Divided 92 by 4 first, then subtracted the sum of 12 and 16 (which would be -5) Divided 92 by 4 first, then subtracted 12 then added 16 Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 Instructional Implications: Students need to be exposed to all ways of representing multiplication and division. Always incorporate situations where subtraction comes before addition and division comes before multiplication (to address the common misconception that you always solve in the order PEMDAS). Also students need to see all types of “groups” – parenthesis, brackets, and in this case the expression 92-(12+16) above the division (fraction) symbol. Giving students a number as the solution, a set of numbers (to use in the expression), a set of parenthesis and instructing them to create a situation is a great problem solving activity for students to increase their conceptual understanding of the effect parenthesis have in different parts of the expression. 2014 Grade 6 Mathematics STAAR Reporting Category 5: Probability and Statistics Question 7 6.10D (Readiness) The student is expected to solve problems by collecting, organizing, displaying, and interpreting data Dual Coding: 6.12A The student is expected to communicate mathematical ideas using language, efficient tools, appropriate units, and graphical, numerical, physical, or algebraic mathematical models Vocabulary: Graph, statement Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 When Taught?

Have students justify their conclusions and evaluate other student conclusions. Provide students with words or sentence stems to use in their conclusions (such as twice, half, the sum of ____ and ____ is greater than _____), so they have practice with that vocabulary and practice with conclusions that are multi-step. Have students label information directly on the table. Use tables and graphs from print or electronic media using contexts students find interesting. Students have seen bar graphs since early elementary school, so always incorporate multiple steps to analyze the information in bar graphs particularly (As in this question where students have to turn number of hours into a start and end time).

Students need to work both ways with rules and tables. Given a table, find the rule and given a rule, find a table. Provide opportunities for students to read and interpret information from tables. Provide opportunities for students to build input-output tables and explain the relationships in terms of input-output. Explaining the relationship in terms of input-output is crucial – in this question a common misconception was that students found a relationship between r and r rather than what the question asked; the relationship between r and g. Students need to be exposed to fractions and decimals within the table and expression (not just integers).

Teach students to write number sentences or equations before performing the operation in a word problem. Have students use a problem solving strategy such as draw a picture, work a simpler problem (re-read it with simple numbers to better understand the context and write a number sentence), or act it out. Consider choosing a problem solving system as a campus to use across grade levels. Practice consistently with benchmark fractions (such as 25%, 20%, 50%, 10% etc) so that students can convert them quickly and easily when embedded in a word problem.

A great introduction through inquiry or discovery is to teach students to measure with a protractor, have them measure the angles and find the sum of the angles in multiple different quadrilaterals and then draw their own conclusions about the relationship with their peers (with triangles as well). Another activity to have students draw their own conclusions is to “challenge” them to draw a quadrilateral with 3 acute angles or 3 obtuse angles (which they will find is not possible). Have them justify in their own words why angles in a quadrilateral have a sum of 360.

Emphasize the importance of finding the total since circle graphs show a part to whole relationship. Provide opportunities for student to think aloud and talk through the decisions they make and the steps they take to solve. With circle graphs, encourage them to communicate their reasoning with and without using specific percentages for parts of the graph – for instance “I knew there would be more chairs than tables because of the ratio 3 to 2” or “the part representing desks would have to be less than half the circle, because 20/80 is less than half of 80” to increase their problem solving and reasoning skills. Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 2014 Grade 6 Mathematics STAAR Reporting Category 1: Number, Operation and Quantitative Reasoning Question 22 6.1B (Readiness) The student is expected to generate equivalent forms of rational numbers including whole numbers, fractions, and decimals Dual Coding: Vocabulary: Length, fraction, equivalent When Taught? Content: 6.1B Process: Cognitive Level: Apply – Students apply their understanding of equivalent fractions, whole numbers, and decimals. Analysis of Distracters Correct Regional Campus/ District Data Answer Data A/F 15% 84/10 is not equivalent to eighty four hundredths B/G 3% 92/500 = 0.184 *C/H 52% Correct D/J 30% Instructional Implications: Provide opportunity for students to represent numbers in different ways but always understand that their values don’t change. Provide opportunities for students to correctly read and write numbers to help them learn place value. Emphasize and expect the formal vocabulary when naming numbers. Don’t say or allow students to say “one point eight four”, read “one and eighty four hundredths” – with fractions as well, don’t accept “92 over 500”, hold out for “92 hundredths”. Have a place value chart in your classroom to reference when asking students to selfcorrect using the formal vocabulary. Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 2014 Grade 6 Mathematics STAAR Reporting Category 4: Measurement Question 23 6.8B (Readiness) The student is expected to select and use appropriate units, tools, or formulas to measure and to solve problems involving length (including perimeter), area, time, temperature, volume, and weight Dual Coding: 6.11C The student is expected to select or develop an appropriate problem-solving strategy from a variety of different types, including drawing a picture, looking for a pattern, systematic guessing and checking, acting it out, making a table, working a simpler problem, or working backwards to solve a problem Vocabulary: Weighed, combined, ratio, closest Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 When Taught?

Have students estimate first to check for reasonableness (and eliminate unreasonable answers in multiple choice questions). Teach students to find the whole when given a ratio that is part to part and emphasize the importance of the whole. Provide students information embedded in images, and diagrams as well as graphs and table. Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 2014 Grade 6 Mathematics STAAR Reporting Category 1: Number, Operation and Quantitative Reasoning Question 24 6.2E (Readiness) The student is expected to use order of operations to simplify whole number expressions (without exponents) in problem solving situations Dual Coding: 6.11A The student is expected to identify and apply mathematics to everyday experiences, to activities in and outside of school, with other disciplines, and with other mathematical topics Vocabulary: Decreased, another, expression, determine When Taught?

Provide opportunities for students to work multi-step problems using order of operations. Have students communicate their thinking and explain why certain operations must be performed first. Giving students a number as the solution, a set of numbers (to use in the expression), a set of parenthesis and instructing them to create a situation is a great problem solving activity for students to increase their conceptual understanding of the effect parenthesis have in different parts of the expression. Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 2014 Grade 6 Mathematics STAAR Reporting Category 1: Number, Operation and Quantitative Reasoning Question 25 6.1B (Readiness) The student is expected to generate equivalent forms of rational numbers including whole numbers, fractions, and decimals Dual Coding: 6.13A The student is expected to make conjectures from patterns or sets of examples and nonexamples Vocabulary: Sets, statement, equivalent, each When Taught?

Analysis of Distracters Able to accurately solve for equivalence when given a mixed number, but not with the improper fractions. Correct Mistakes seven tenths in the fraction form for seven hundredths in decimal form and incorrectly converts improper fractions Mistakes seven tenths in the fraction form for seven hundredths in decimal form Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 Instructional Implications: Provide opportunity for students to represent numbers in different ways but always understand that their values don’t change. Provide opportunities for students to correctly read and write numbers to help them learn place value. Emphasize and expect the formal vocabulary when naming numbers. Don’t say or allow students to say “eight point seven”, read “eight and seven tenths” – with fractions as well, don’t accept “92 over 500”, hold out for “92 hundredths”. Have a place value chart in your classroom to reference when asking students to self-correct using the formal vocabulary. 6.13A The student is expected to make conjectures from patterns or sets of examples and nonexamples Students need to be exposed to this process skill with more than just equivalent fractions. They should be able to group types of numbers and identify non-examples. Provide opportunities for this and for students to think aloud and talk through the decisions they make. Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 2014 Grade 6 Mathematics STAAR Reporting Category 3: Geometry and Spatial Reasoning Question 26 6.6C (Readiness) The student is expected to describe the relationship between radius, diameter, and circumference of a circle Dual Coding: 6.11D The student is expected to select tools such as real objects, manipulatives, paper/pencil, and technology or techniques such as mental math, estimation, and number sense to solve problems Vocabulary: Line segment, passes through, center, circle, coordinate grid, equation, circumference When Taught? Content: 6.6C Process: 6.11D Correct Answer *A/F B/G Regional Data 65% 26% Campus/ District Data Cognitive Level: Apply - Students must use the information provided in the coordinate grid and apply the formula for circumference of a circle Analysis of Distracters Correct Uses the formula for circumference given the radius, but incorrectly inputs the value for diameter (60). Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 C/H 5% 60x2=120, and uses the formula that would solve for radius, not circumference 60/2 would solve for radius, not circumference D/J 4% Instructional Implications: Provide opportunities for students to know and understand the relationships that exist between the radius, diameter and circumference. They should calculate: circumference with radius, circumference with diameter, diameter with circumference, radius with circumference, diameter with radius, and radius with diameter. Have students explain what the components of various equations mean in relationship to finding the diameter, radius or circumference. Provide opportunities for students to know and understand the formulas used for circumference and manipulate these formulas. When using coordinate grids, have students find the distance between two points. Use a variety of increments so they have the experience and exposure working with various values in coordinate grids.

Analysis of Distracters Cannot be correct because 2 1/3 – (5/6 + ¾) is less than 1 ½ Cannot be correct because 2/3 < ¾ Cannot be correct because 5/6 + 5/6 + ¾ is 2 5/12 not 2 1/3 Correct Region 10 Item Analysis – 2014 6th Grade Math STAAR, Part 1 Instructional Implications: Provide opportunities for students to work multi-step problems, especially with fractions, decimals and percent. Teach students to write number sentences or equations before performing the operation in a word problem. Have students use a problem solving strategy such as draw a picture, work a simpler problem (re-read it with simple numbers to better understand the context and write a number sentence), or act it out. Students need to be comfortable with reading long questions, identifying multiple informational elements within the question, plan and carry out a solution. Consider choosing a problem solving system as a campus to use across grade levels. Have students communicate their thinking.
