This number sorting resource is perfect for children learning about the different representations of teen numbers.

A hands-on way to learn about number that can be used over and over and over again to help support your classroom teaching of number and all the different ways numbers can be represented. With multiple representations included for all the numbers from 11-20, pick and choose the cards you want your children to sort. Choose from number words, ten frames, tally marks, number lines, tens and ones, MAB blocks, dots, dice and more.

This sorting activity is a fantastic addition to your math centers or morning work!

Alternatively use the cards alone as a game of Snap! Or use them to display in class as posters.

  • number mats 11-20 (2 designs - full color + print friendly color border/white background) - 2 per A4 page
