Modelling Decimal Multiplication (with practice)

This is meant to help to model decimal multiplication by using the area model of multiplication. It starts with the area model for two digit by two digit multiplication of whole numbers as an optional review (or an introduction). Then it moves to decimal multiplication with an example that you can use to discuss. Both the whole number and decimal divisions have slides with randomly generated questions for students to practice. All of the practice questions are self checking.
