Using Estimation Strategies

Topics for Today:

Today we discussed some strategies for estimating the answers to numeric expressions.  Students were asked to consider both how to estimate as well as the reasons why we use estimation.  We will spend a lot of discussion time this school year on number sense, and determining if our solutions to problems make sense.
