Eureka Math Kindergarten, Module 5: Numbers 10-20 and Counting to 100
In this unit, your child's numbers grow past 10. Kindergartners see each teen number as ten ones and some more ones, notice that each counting number is exactly one more than the one before, count on from any number, and count to 100 by ones and tens. The number pairs from the last unit help here, and the year ends with comparing and building shapes.

What is my child learning in Module 5?
- Counting to 100 by ones and tens, and noticing that the tens follow the same pattern as 1, 2, 3. Learn more about counting to 100 by ones: Counting to 100 by ones · Learn more about counting to 100 by tens
- Counting on from a number other than 1, such as 14 or 52, to keep a count going. Learn more: Counting on from any number
- Understanding that each number in the count is one more than the number before, so 16 is 15 and one more. Learn more: How counting tells you how many
- Showing teen numbers as ten ones and some more ones with objects, drawings, and equations like 10 + 7 = 17. Learn more: Teen numbers as ten and some more

Question 1 of 3
What comes next? 10, 20, 30, 40, __
- 60
- 50
- 41
How you can help
- Line up 10 shoes and add one more at a time, asking your child each time what the new number is without recounting from 1.
- Hold up both hands and count by tens with your child, 10, 20, 30, flashing all ten fingers for each number until you reach 100.
- Start counting from a teen number on a walk, such as 13, and let your child continue the count until you reach the next corner.
Where kids can get stuck
- Recounting all 12 objects after one more is added, instead of knowing the new total is 13.
- Freezing when asked to start counting from a teen number, such as 13, though starting at 4 is easy.
- Showing 15 with 1 block and 5 blocks, thinking the 1 stands for one object.
