Teacher's field guide

What Students Need to Do: Students sort items or responses into groups and record one tally mark for each. They draw a picture graph with one picture for each item and label the groups.
What Mastery Looks Like: Given a small set of votes, a student makes a tally chart and picture graph with matching counts. They label each group and can check each picture against a tally mark.
Common Misconceptions: Some students make one tally mark for a whole group instead of one per item. Others draw one picture for each group instead of each item, or leave groups unlabeled.
How to Assess It: Give students 4 apples, 2 pears, and 3 bananas. Ask them to make a labeled tally chart and a picture graph with one picture for each fruit.

Lesson moves
