## Unit 1: Number and Operations in Base Ten

Unit 1: Number and Operations in Base Ten

- MGSE3.NBT.1 Use place value understanding to round whole numbers to the nearest 10 or 100.
- MGSE3.NBT.2 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.

In this unit, students will learn to estimate by rounding numbers to the nearest ten or hundred. Additionally they learn strategies to add and subtract numbers within 1000. We also review place value and the properties of addition.
