Focus Question: What strategies can I use to multiply decimals?

This is our first year with this new curriculum, Reveal Math.

This sixth unit is all about understanding the different strategies of multiplying decimals by whole numbers and multiplying decimals by decimals. Within this unit, we will look at patterns when multiplying by powers of 10, estimating products, 100's chart to multiply, area model to solve for products, partial products to solve for products, the standard algorithm, and solving word problems.
