Distributive Property and Expressions

This lesson, led by Mr. Hul, focuses on writing products as sums and sums as products. It begins with a problem involving dividing money between George and Ben using a ratio, solved through tape diagrams. The lesson progresses to explaining rectangular arrays and their application in representing expressions. The distributive property is introduced and applied to calculate areas and expand expressions. Advanced examples and exercises are provided to reinforce the concepts, emphasizing visualization techniques like tape diagrams and arrays.
