Math Unit 2!

Unit 2: Addition Within 200

In this unit we will be working with place value, representing numbers in different ways, and comparing numbers. We will be adding two, three, or four digits numbers, sometimes resulting in new tens or new hundreds, with sums to 200.

The big ideas within this unit include:

Representing numbers using base-ten numerals, expanded form, and word form

Visually showing numbers to 200 in different ways

Applying addition concepts and strategies to real world situations, and solve 2-digit addition problems. 

Money and fluency for addition within 100
