Use this sheet for a variety of addition activities. I often use this sheet in centers for a "fishing" game. Set out a basket of magnetic numbers with some "fishing rods" (paper clips tied to some string). Students fish for 2 numbers and record their results on this sheet.
For example, if a student caught a red 2 and a blue 6, he or she would draw 2 red dots (or fish) and 6 blue dots, and then record the number sentence 6+2=8.
