**Focus: *MP4: Modeling and MP6: Attend to Precision**

What did Chris do well?

Sample answer: Chris drew clear pictures of the 5 cups and divided them well into groups of ¾.

What could Chris do better next time?

Sample answer: Chris mistakenly said that there was ½ left over. This is incorrect because there are 2 of 3 parts left over, not ½ left over, so it would be 6 full containers and 2/3 of a container left.
