More Numbers

Here are some number cards for 11-20. You can use these for a variety of things, but I will make a copy for each set of partners in my class. Students will lay the cards out on the floor. One partner will close their eyes while the other partner removes a card. The student has to open their eyes and determine which number is missing. You can also have your students scramble the cards for their partner and then they must put them back in order.
