About this worksheet
Three number trains with empty cars. Kids count on and write the missing numbers in big boxes.
What kids practice
Counting out loud in order is the very first number skill. Kindergartners start by counting to 20 without skipping or repeating, then learn to count by tens to 100. By the end of the year most kids can count to 100 by ones too.
Watch for
- Skipping a number or saying one twice, especially in the teens.
- Saying "eleventeen" or "tenty". The teen and ty names take practice.
- Getting stuck at a decade change, like going from 29 to 30.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full counting to 20, then to 100 guide for kindergarten.
