What you'll learn

  • Ask a question and collect data to answer it
  • Show data with object graphs, picture graphs, and tables
  • Read a graph to answer questions about the data

Words to know

Data —
information you collect
Object graph —
a graph made with real objects
Picture graph —
a graph that uses pictures
Table —
a chart with rows and columns
Most —

Worked examples

Model ItI do

A picture graph shows 5 apples and 3 bananas. Which fruit has more?

Count the pictures for each fruit. There are 5 apples and 3 bananas. Since 5 is more than 3, there are more apples.

Try It TogetherWe do

Using the same graph, how many more apples than bananas are there?

There are 5 apples and 3 bananas. Subtract to compare: 5 - 3 = 2. There are 2 more apples than bananas.

Now YouYou do

Using the same graph, how many pieces of fruit are there in all?

Add the apples and bananas together. Check your answer in the back of this chapter.
