4. Three Skills to Improving Students Score Understanding the Rubrics Recognizing the actions Completing each action

5. Understanding the Rubrics Ensuring students understand: – the language of the rubrics using the Cues for Students –the difference between ECR and BCR rubrics

6. BCR Rubric Level 3 The response indicates application of a reasonable strategy that lead to a correct solution in the context of the problem. The representations are essentially correct. The explanation and/or justification is logically sound, clearly presented, fully developed, supports the solution, and does not contain significant mathematical errors. The response demonstrates a complete understanding and analysis of the problem.

7. ECR Rubric The response indicates application of a reasonable strategy that leads to a correct solution in the context of the problem. The representations are correct. The explanation and/or justification is logically sound, clearly presented, fully developed, supports the solution, and does not contain significant mathematical errors. The response demonstrates a complete understanding and analysis of the problem. Level 4

8. Cues for Students Puzzle 1. Lay out the words in all capital letters! 2.Sort the strips in each individual envelope and place the strips next to the words that best explain the AREA J categories!

9. Cues for Students ANALYSIS Consider what the question asks you to do. What information is given in the problem? What information do you need to solve the problem? Think about what you would do to solve the problem. EXAMPLE: To solve this problem, I must: -find out how many feet of fencing it will take to enclose Wanda’s garden. -use the formula for perimeter of a rectangle, because I know it has one side of 18 feet and one side of 12 feet and that would make a rectangle shaped garden.

10. Cues for Students REPRESENTATION Write an equation or inequality. Define the variables. Let x = ____ and/or let y = ____. Create a graph, chart, or table. Include titles, axes, labels, and scales. Create a drawing or construction. EXAMPLE: Let P = perimeterP = 2(18 feet) + 2(12 feet) Let l = length l = 18 feet Let w = widthw = 12 feet 12 feet Wanda’s garden

11. Cues for Students APPLICATION Solve the problem. Write the answers in the context of the problem. Be sure you answer what is asked for in the problem. Check to see if the answer is reasonable. P = 2(18 feet) + 2(12 feet) P = 36 feet + 24 feet P = 60 feet EXAMPLE: It will take 60 feet of fencing to enclose the entire garden.

12. Cues for Students EXPLANATION Write or describe the steps you used to solve the problem. EXAMPLE: If Wanda’s garden is 18 feet long and 12 feet wide, then P = 2(18 feet) + 2(12 feet), and that equals 60 feet.

13. Cues for Students JUSTIFICATION Use mathematics (definitions, theorems, reasoning, principles) to support your solution and/or process. Write the mathematics concepts you used. Tell why you solved the problem as you did. Demonstrate that the solution is correct. EXAMPLE: I know 60 feet is a correct answer because, I used the formula to find the perimeter of a rectangle,. 60 = 2(18 feet) + 2(12 feet) 60 = 36 feet + 24 feet 60 = 60 

14. AREA J Respond to all BCRs and ECRs using AREA J ANALYSIS: WHAT IS THE PROBLEM ASKING AND WHAT MATHEMATICAL METHOD DO I USE TO SOLVE THE PROBLEM? EXPLANATION: WHAT DID YOU DO TO SOLVE THE PROBLEM. ANSWER THE ORIGINAL QUESTION IN A COMPLETE SENTENCE. USE MATHEMATICAL TERMS. APPLICATION: SOLVE THE PROBLEM. SHOW ALL THE WORK. REPRSENTATION: GRAPH, TABLE, DRAWING, EQUATIONS WITH VARIABLES DEFINED JUSTIFICATION: HOW DO YOU KNOW YOUR ANSWER IS CORRECT?

15. Explanation refers to the student using the language of mathematics to communicate HOW the student arrived at the solution Justification refers to the student using mathematical principles to support the reasoning used to solve the problem or to DEMONSTRATE the solution is correct This could include the appropriate definitions, postulates and theorems Knowing the Difference Explanation and Justification
