1. Draw a diagram and write an explanation of the distributive property using 4×8=4×5+4×3 as an example.
2. Explain how to use your favorite version of the multiplication by 9's trick, and explain why it works.
3. Draw an array diagram for 36x24, and show how it corresponds to the expanded algorithm for multiplication.
