Go Math! Kindergarten, Chapter 3: Represent Count and Write Numbers 6 to 9
In this unit, your child extends counting to 6, 7, 8, and 9. Kindergartners show each number as 5 and some more, count larger groups without losing track, and practice writing these new numerals, which can be tricky to form. The comparing work from the last unit still applies, and next your child gives special attention to the number 10.

What is my child learning in Chapter 3?
- Writing the numerals 6, 7, 8, and 9 and matching each one to a group of that size. Learn more: Writing numbers from 0 to 20
- Counting groups of 6 to 9 with one number for each object, and seeing that 8 is one more than 7. Learn more: How counting tells you how many
- Showing 6 to 9 as 5 and some more, on fingers or in a row, and counting out that many objects. Learn more: Counting groups of up to 20 things
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
How many apples do you see?
- 9
- 7
- 8
How you can help
- Show numbers 6 to 9 with one full hand and some more fingers, and let your child say how many fingers are up.
- Ask your child to count out 8 spoons or 9 socks, moving each one aside as it is counted so none get counted twice.
- Write 6, 7, 8, and 9 on sticky notes, stick them on doors around the house, and let your child knock that many times on each door.
Where kids can get stuck
- Mixing up 6 and 9 when reading or writing them, since the numerals look so alike.
- Skipping an object or counting one twice in a group of 9, without moving each one aside.
- Recounting all 6 objects after one more is added, instead of knowing the new total is 7.
Practice makes perfect
Bobby's Math Club has practice problems that adapt to your child’s level, each with a detailed explanation and an easy-to-follow video, so your child can build confidence in these skills one step at a time.
Words your child will hear
- numeral
- The written symbol for a number, like 7.
- count

- one more
- The next number when counting; one more than 6 is 7.
