## Reflection: Developing a Conceptual Understanding Rounding and Estimation, Day 2 - Section 4: Elevator Speech

Rounding and Estimating - put together - is a GREAT TOOL. Make sure you teach it well. It is essential for checking work. It is great for testing. Do not underestimate the power of rounding and estimating.

When I first started teaching I didn't understand why it was important. Now I take extra time, if needed, to make sure my students have a firm grasp of the concept. We use it all the time!

These place value lessons are taught first every year. Do not assume your students understand place value. It is the cornerstone of the whole year. Games are a great way for students to work with place value and extract a real understanding of the concept. My students LOVE learning in this environment.

You don't have to just use these games, get creative. Think dice, cards, anything you can think of to get them excited. Check you local game store, or even thrift stores. There are a lot of games that use place value. Or take a old game and give it new rules!

Do not short change place value. It is too important for the students to not have a solid knowledge of what it means!
