I made these number cards because I wanted to have the kiddos use them for higher level thinking and order of operations. I print them out on regular paper, affix them to card stock or colored paper and laminate them so they last a long time. I use them for center work, manipulatives and teaching as well as game time. For some things I prefer them over playing cards because I can color code them for easy clean up and they have the operation signs as well.
Enjoy my freebie!!!
