One activity that may fill in the gap for a couple of days are missing addend flashcards. I included addition sentences with missing start, change and end numbers. I used numbers that were a little less friendly and a little larger to make it a bit more challenging. I also laminated them so they could use an Expo marker and be able to use them many times.

Students also began to learn about the commutative property of addition - 8 + 3 = 11 and 3 + 8 = 11.
There is also just something about being able to use markers that kids find irresistible!
