Illustrative Mathematics Kindergarten, Unit 8: Putting It All Together
In this unit, the year ends by bringing everything together. Your child revisits counting to 100, adding and taking away, teen numbers as ten and some more, measuring, and naming shapes and where they are, often through games and projects. After the measuring unit, this review helps each skill feel secure and shows how kindergarten math fits together, so your child heads to first grade confident.

How you can help
- Count by tens to 100 on a walk or ride, then count back down to a teen number and name it as ten and some more.
- Set up a toy shop with price tags from 1 to 5, and let your child add the prices of two toys together.
- Describe something in the room by its shape, size, and position, such as 'a tall rectangle beside the window,' and let your child guess what it is.
Where kids can get stuck
- Mixing up 'taller' and 'longer,' or using 'big' for every difference in size.
- Getting stuck at the end of a group of ten, saying 'sixty-ten' instead of seventy.
- Adding both numbers in a story even when some of the things went away.
