These numbers show how many books students read last month: 2, 4, 1, 3, 2, 5, 4, 2. Which number of books appears most often?

You asked classmates to name their favorite snack. The choices were crackers, fruit, yogurt, and popcorn. What kind of graph would be a good way to show these category data?

A pictograph shows books read this week. Each book picture stands for 1 book. Ana has 3 book pictures, Ben has 5 book pictures, and Cam has 2 book pictures. How many books did they read in all?

A line plot shows the number of pets students have. There is 1 X above 0 pets, 3 Xs above 1 pet, 2 Xs above 2 pets, and 1 X above 3 pets. How many students have 1 or 2 pets?

A class recorded how students get to school. Bus = 6, walk = 4, bike = 2, and car = unknown. If 15 students answered in all, how many students came by car?
First add the numbers you know. Then subtract from the total.
Three students came by car. The known total is 6 + 4 + 2 = 12, and 15 - 12 = 3. - 14

A class collected data about favorite playground games: tag = 9, swings = 6, slide = 4, and jump rope = 5. Write a good title and labels for a bar graph of these data.
A graph title tells what the graph is about. Labels tell what the categories and numbers mean.
A good title is Favorite Playground Games. The labels should be Games for the categories and Number of Students for the counts.
