Finding Missing Parts in Whole Numbers

The video tutorial explains how to find missing parts in a part-whole model using simple counting techniques. It provides multiple examples where the whole is given, and students need to determine the missing part by counting on from a known part. The video includes interactive elements to engage students in solving the problems themselves.
