What This Standard Means
What Students Need to Do
- Students sort or collect information into categories and count each group. They show those counts with pictures or bars placed in labeled categories.
What Mastery Looks Like
- Students organize category counts and represent each amount accurately. Their graph has clear category labels, equal units, and bars or pictures that match the data.
Common Misconceptions
- Students may draw bars with gaps that do not match the categories or start bars at different baselines. They may also count pictures incorrectly or use pictures of different sizes as different amounts.
How to Assess It
- Give students these results: cats 4, dogs 2, fish 3. Ask them to make one picture graph and one bar-type graph with labels.

Ways to Teach It
Survey favorite fruits, stack linking cubes for each choice, then draw bars that match the cube stacks.
Display a class graph and ask, "How do you know each bar shows the correct number?"
Give pairs category cards and count cards, then have them race to build an accurate graph with tiles.
Track sunny, cloudy, and rainy days for two weeks, then make a graph for the class weather board.
