Score & Description  
 
 

In this question the student was asked to compare the sale price of a stereo, after 3 weeks, based on two different ways for reducing the price. In one store, the price was reduced each week by a fixed amount (10% of $100, or $10). In the other store the price was reduced each week by a varying amount (10% of the current price, which is less each week). To earn full credit, the student needed to indicate that the price would be less at the first store after 3 weeks and explain how the solution was obtained. Students were permitted to use a calculator.

Scoring Guide 
Solution: Maria will win the game. The following reasons may be given:
Scoring Guide In this question a student needed to use number skills to understand place value and compare numbers. Since Carla placed her number 1 tile in the hundreds place, the greatest number she could have after subtracting would be less than one hundred. Maria could have used the number 2, 3, or 4 tile in the hundreds place and her difference would always be larger than Carla's. For an extended response, the student needed to answer Maria and demonstrate understanding of place value by generalizing a comparison of the possible differences that Carla could obtain to the possible differences that Maria could obtain. ("Generalize" means that the student indicates that since Carla placed her number 1 tile in a place so that she would never win, Maria would always win, no matter how she placed her 2, 3, and 4 tiles.) For a satisfactory response, a student needed to demonstrate understanding that Maria could make a larger top number than Carla, but the response did not generalize Maria's and Carla's possible differences. For a partial response, a student had to provide an explanation that was only partially correct; however, those types of responses did recognize that Maria would have the greater number after determining the difference. A minimal score was earned by responses that indicated that Maria would win, but did not offer an explanation for how Maria would win the game.

Solution: Brian (constant difference) Scoring Guide In this question, a student has to use mathematical reasoning to construct different justifications that support Darlene’s and Brian’s claims. In this realworld problem, students have to construct an appropriate method for supporting each claim in the question. One such method uses proportional thinking as well as percentages to explain how a conclusion could be reached, while the other involves comparing differences in growth by subtraction. Partial credit is earned if a student just gives a correct justification for Brian’s or Darlene’s claim, but not both, or shows a limited understanding of how to proceed with the problem.

Scoring Guide 
Solution: They will both reach points A and B at the same time because their rates are equal. Scoring Guide In this question, a student needed to use proportional thinking to solve this problem. The student should have reasoned that both Victor’s rate and Sharon’s rate are equal. To earn full credit the student needed to answer both parts of the question correctly with the correct justification for each. To earn partial credit, a student could have just answered one part correctly with the correct justification or answered both parts with no justification or incorrect justifications.

Solution: Treena's fixed expenses will be 7 × 45 = $315 for the 7 days. Therefore, she has 1000  315 = 685 to spend for instruction and travel. The group plan will cost 7 × 40 = 280 while the individual plan will cost 7 × 60 = 420. Treena has three options: Group and Train: 280 + 125 = 405
(720)$280 left She cannot choose the individual plan and travel by plane because her total expenses would be $1,070 which is greater than the allotted scholarship. (This can be considered as a valid conclusion but can only be counted in a score of Minimal or Partial.) Any full credit response clearly communicates that Treena has three options, what the three options are, and how the student arrived at the three options.
