Three Skills to Improving Students

Score

Understanding the Rubrics

Recognizing the actions

Completing each action

Understanding the Rubrics

Ensuring students understand:

– the language of the rubrics using the Cues for Students

– the difference between ECR and BCR rubrics

BCR RubricLevel 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.

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!

Cues for StudentsANALYSIS

•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.

Cues for StudentsREPRESENTATION

•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 = perimeter P = 2(18 feet) + 2(12 feet)Let l = length l = 18 feet Let w = width w = 12 feet

12 feetWanda’s garden

Cues for StudentsAPPLICATION

•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 feetP = 60 feet

EXAMPLE:It will take 60 feet of fencing to enclose the entire garden.

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.

Cues for StudentsJUSTIFICATION

•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 feet60 = 60

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?

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
