Pictograph

Union Elementary School is collecting cans to recycle. The principal made a picture graph to

show how many bags of cans were collected by each grade level. Use the graph to answer the

following questions.

How many bags of cans did the fourth grade collect?

Answer explanation

Make sure to look at the key at the bottom of the graph. It tells you that each can is worth 10 bags, so fourth grade collected 40 bags of cans. 10+10+10+10=40

How many grades collected more than 40 bags of cans?

How many more bags of cans did second grade collect than first grade?

Answer explanation

Second grade collected 70 bags of cans. First grade collected 30 bags of cans. To find out how many more that second grade collected than first grade, you have to take 30 bags away from 70 bags. 70-30=40 so second grade collected 40 more bags than first grade.

How many bags of cans did third grade and fourth grade collect together?

Answer explanation

Third and fourth grade both collected 40 bags of cans. We have to add 40 bags plus 40 bags to figure out how many they collected all together. 40+40=80 Think doubles!!

If Kindergarten collected 20 more bags of cans, how many pictures would need to be

added to the graph?

Answer explanation

Since one picture of a can is 10 bags, and 10+10=20, kindergarten would need to add two more pictures if they collected 20 more cans.
