I created this True or False Math Center to reinforce CCSS 1.OA.7.
I made six facts for each number 1-10 for subtraction and for addition. On each page you will find three false and three true number sentences. I also included a page of blank cards so you may create your own or additional facts. Students need to match the addition or subtraction number sentences with either the True or False card.
In my room, I printed the papers on card stock and then laminated them for math centers.
I also have 12 practice papers to go along with the center. I use these as morning starter papers after the math center has been up and running for a while.
