What This Standard Means
What Students Need to Do
- Students read pictographs and bar graphs to compare category values. They identify which categories have the greatest, least, or equal amounts and explain their findings with graph evidence.
What Mastery Looks Like
- Students correctly name categories with the greatest, least, and equal values. They state or write a clear comparison and support it with numbers from the graph.
Common Misconceptions
- Students may choose the tallest picture instead of using the pictograph key to find its value. They may overlook ties or confuse the greatest category with the category listed first. Some give an answer without citing values from the graph.
How to Assess It
- Show a bar graph with apples 8, bananas 5, oranges 8, and pears 3. Ask students to name the greatest, least, and equal categories, then support each answer with numbers.

Ways to Teach It
Have students build a class snack-preference graph with linking cubes, then label the greatest, least, and equal categories.
Ask students to write three claims about a graph and cite a number from the graph for each claim.
Play Graph Detective by showing pictographs and awarding points for finding the greatest, least, or tied categories accurately.
Use a cafeteria menu survey, graph the class responses, and write which item should be prepared most and why.
