Free 100 Number Grid

A fun way for kids to play with numbers, patterns and develop their number sense is with 100 grids. Here are some different patterns that can be colored on the grids.

The first one is all the even numbers or counting by two's.

Counting by three's creates a diagonal pattern.

On this all the double numbers are colored (11, 22, 33, 44,...., 99) which is the same as counting by eleven's.

Try coloring other patterns to see what happens. Try counting by fours starting on the number five  (5, 9, 13, 17.......) or the Fibonacci pattern (add the sum of the two previous numbers in the pattern to get 1,2,3,5,7,12,19,31......).

To make this activity easier I created a Blank 100 Grid and a Filled in 100 Grid.

Please feel free to make use of them.


  1. OH what a great post! I found this in a round-about way, via the hip homeschool moms weekly linkup and would LOVE it if you could share your post on Homeschooling on the Cheap!


    1. Done! Thank you for letting me know about your blog hop. I will check back again in a few days.

  2. Great thinking activity! I keep meaning to have my son do some work on these, but honestly math is not a focus this year. He's only 4, so I don't try to do 'math' every day. I love how this makes numbers visual so they can actually see what is happening! Thanks for linking up to Trivium Tuesdays! Thanks for sharing your grids too!
