Read and Interpret Scaled Picture Graphs

Students will read picture graphs where each picture represents more than one object (e.g., each symbol = 2 or 5). They will answer questions about the data including how many more/fewer, totals, and comparisons.

Pictures in a graph stand for more than one.

The key tells the value of each picture.

Read it: Each picture is worth the key

This picture graph shows books read each day. The key says each picture stands for 2 books, so a row is worth more than its pictures.

Read the key first: each picture stands for 2 books.
Count a row by 2s: Tue has 6 pictures, so 2, 4, 6, 8, 10, 12 books.
Compare two rows: Tue 12 and Wed 2 are 10 apart.

One picture for every 2 books keeps a big count short enough to draw.

Counting by the key turns pictures into books: 6 pictures of 2 is 12.

How many more is the gap between the rows' values: 12 take away 2 is 10.

Find the key, count each row by the key, then compare.

Reading Tue as 6 books because the row has 6 pictures, and forgetting the key.

Each picture is 2 books. Count by 2s: Tue shows 12 books.

In a picture graph, each picture stands for 4 birds. One row has 5 pictures. How many birds does that row show? — 20. 5 pictures, each 4: count by 4s to 20.

Favorite Fruits picture graph (each 🍎 = 2 votes)

Class voted for their favorite fruit. We made a picture graph to show the votes.

Look at the key first. Each apple picture stands for two votes — not just one!

Three fruits: apples, bananas, and grapes. Each row shows how many people picked it.

Apples has four pictures. Let's count by twos: two, four, six, eight.

So eight people voted for apples.

Bananas has three pictures. Two, four, six. Six votes for bananas.

Grapes has two pictures. Two, four. Four votes for grapes.

Question time! Look at the graph. How many more people picked apples than grapes?

Grade 3 · Each picture stands for more than one

Apples got eight, grapes got four. We subtract to compare.

Eight minus four is four.

Four more people picked apples than grapes. Great job reading the scaled graph!

Now you try. Use the key. Type how many Apples. How many Apples are shown?
