This is an activity you can use in two ways!
First you can have students cut the cards, sort them into their matches, and then glue on chart paper.
Or you can make a few sets and place in a center as a sorting activity or a concentration game.
12 standard form cards are included. Each card has a matching word form, expanded form, and base ten blocks.
This matches standard 2.NBT.3
My classroom pictures and how to directions are included
