### Work the Following on Your Own Paper…

Luis mixed 6 ounces of cherry syrup with 53 ounces of water to make a cherry-flavored drink, Martin mixed 5 ounces of the same cherry syrup with 42 ounces of water. Who made the drink with the stronger cherry flavor?

### Let’s Discuss

Looking at some responses…

What is the mathematical evidence?

What makes “good” explanation?

Solving a Simpler Problem
• Create a set of 4 related, but simpler problems
• Each group should work one problem
• Work together
• Make sure everyone in the group can solve the new problem
• Be ready to share the solution and solution strategy
Solving a Simpler Problem
• Share the solution and solution strategy with your new group
• Look back to the original problem and discuss with the group
• Was your thinking correct on the original problem?
• Did you use a similar strategy on the simpler problem and the original problem?
• Can you apply a new strategy?
• A grading rubric is used to show students exactly what the expectations are for a task that is being assessed.
• Rubrics help provide some credit for correct thinking even if the answer to the task is not exactly right.
• Typically, a rubric scores with points ranging from 0 to 4 and includes a description of the characteristics of a response that ranks at each levels.
• Share your characteristics for each level beginning with level 0
• Record each groups’ ideas in one list
• Decide upon a rubric for the whole class
How did you do?
• Assess the following student responses using our rubric.
• As you assess other student work, think about
• What constitutes a complete justification?
• Why is the justification important?
NAEP Scoring Guide
• Compare the rubric your class created to the scoring guide from NAEP
• Compare your scoring of student work to the score NAEP would assign
