Let’s Learn!

Amelia collected data from her classmates. Data is information collected by asking questions. Here is her data:

We can organize Amelia’s data by using tally marks. Tally marks are a way of counting by drawing lines. They look like this:

The fifth tally mark crosses over a group of four tallies to make a bundle. Tally marks help us count quickly.

Let’s make some tallies! How many students like strawberry ice cream?

Now let’s use our tally marks to create a bar graph. A bar graph is a graph that uses bars to show numbers so that we can easily understand them.

This is an empty graph. We will use Amelia’s data to make bars inside it!

5 students like strawberry ice cream, so let’s color a bar up to the number 5.
