Addition can be thought of as combining two quantities and finding the total. To add 2 + 5, combine 2 yellow counters and 5 red counters. There are 7 counters in total, so 2 + 5 = 7. Addition can also be thought of as combining two parts to make a whole. A part-part-whole model can be used to discover different ways that two numbers sum to 7.
