This activity is a great way for students to practice adding 1 and 10 to numbers 1-120. Before hand, cut out number cards in strips or individually.
I use this activity as a math center. To make the center more student friendly, I cut the number cards into strips. I feel students will less likely miss a card.
For a whole group activity, divide up the cards among students. Use the cards like a Scoot game and have them change cards every thirty seconds or so.
