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

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

This eighth unit is all about understanding the different strategies of dividing decimals. Within this unit, we will look at patterns when dividing, estimating quotients, partial products, standard algorithm (long division), and solving word problems.
