Go Math! Grade 1, Chapter 10: Represent Data
In this unit, first graders collect data, or information, by asking questions and counting answers. They sort it into up to three categories and show it with tally charts, picture graphs, and bar graphs. Then they read the graphs to find totals and how many more or fewer. After measurement in the last unit, this uses counting to answer real questions, and next they study solid shapes.

What is my child learning in Chapter 10?
- Making tally charts, picture graphs, and bar graphs with up to three categories, then reading them to answer how many more or fewer. Learn more: Sorting, tallying, and reading simple charts
Sample questions to try together
These are real questions from our practice. Tap the speaker to hear one read aloud, or the light bulb for a hint, and talk about the answer together.
Question 1 of 3
The bar graph shows students' favorite fruits. How many students chose bananas as their favorite fruit?
- 4
- 3
- 5
How you can help
- Ask family and friends a question with three answers, like their favorite season, and keep tally marks. Count the tallies by fives together.
- Turn the tallies into a bar graph on paper, coloring one square for each vote. Ask which category has the fewest votes.
- Sort a basket of toys or socks into three groups and ask how many there are altogether and how many fewer are in the smallest group.
Where kids can get stuck
- Reading the tallest bar's number when asked how many more it has than another bar.
- Miscounting bundled tally marks, counting the slash in a group of five as a sixth.
- Adding only two groups when asked how many there are in all three categories.
