PTA State Assessment Review 2013 September 12th, 2013
Sample Question - 3thGrade Math • Domain: Operations and Algebraic Thinking • Item: MC • Two groups of students from Douglas Elementary School were walking to the library when it began to rain. The 7 students in Mr. Stem’s group shared the 3 large umbrellas they had with Ms. Thorn’s group of 11 students. If the same number of students were under each umbrella, how many students were under each umbrella?
Alignment & Analysis • Aligned CCLS: 3.OA.8, 3.OA.2 • Commentary: This question aligns to CCLS 3.OA.8 and assesses the student’s ability to solve a two-step word problem using addition and division of whole numbers. It also aligns to 3.OA.2 because it assesses the ability to partition a number into equal groups. • Rationale: The total number of students in the two groups is 18 (7 + 11), so 18 must be divided into 3 equal groups; therefore, 6 students are in each group. Selecting Options B and D could indicate relating of the numbers in the problem with incorrect operations (adding 7 and 3 in B and multiplying 7 and 3 in D) and therefore a lack of understanding of the problem. Selecting Option C indicates that a student had knowledge of how to begin the problem, by adding the two groups together, but then forgot to divide the students into 3 equal groups.
Sample Question - 8th Grade Math • Domain: Functions • Item: CR • A trainer for a professional football team keeps track of the amount of water players consume throughout practice. The trainer observes that the amount of water consumed is a linear function of the temperature on a given day. The trainer finds that when it is 90°F the players consume about 220 gallons of water, and when it is 76°F the players consume about 178 gallons of water. • Part A: Write a linear function to model the relationship between the gallons of water consumed and the temperature. • Part B: Explain the meaning of the slope in the context of the problem.
Alignment & Analysis • Aligned CCLS: 8.F.4 • Commentary: This question aligns to CCLS 8.F.4 because it assesses a student’s ability to construct a function that models a linear relationship from a description of a relationship between two values (x,y) and interpret the rate of change. • Rationale: The correct answer indicates the ability to construct a function to model a linear relationship. Given that water consumption is a function of temperature, the values cited in the problem are understood as coordinate pairs that can be related by a linear function.
