Part-Part-Whole Model Problems

The video tutorial explains the concept of missing addends using a part-part-whole model. It provides examples and practice problems involving balloons to illustrate how to find a missing part by either adding or subtracting known values. The tutorial emphasizes understanding the whole and known parts to determine the missing part, encouraging practice to master the concept.

What does the top part of a part-part-whole model represent?
