Use these workmats and optional number and animal cracker cards to have a BLAST decomposing and composing numbers! The directions were not included on the workmat, so you could turn this into a center or a whole group lesson. The page with 2 ten frames could be used to show a number in two ways (ex. 8 the number 8 as 4+4 on the top frame, and then 6+2 on bottom frame) or, you could use the 2 ten frames for the numbers 11-20. We had so much fun using iced, plain, and chocolate animal crackers to decompose numbers as a whole group, and then used the optional picture cards in a center.
