To add two numbers, like 3 + 4, place 3 tiles of one color and 4 tiles of another. There are 7 tiles in total, so 3 + 4 = 7. Explore other ways that two numbers can be added to make 7. To find the missing addend in a sum, like 3 + ? = 5, make a row of 5 tiles and below it a row of 3 tiles. The missing addend is 2 because 2 more must be added to 3 to make 5.
