**Chapter 1: **

Essential Question: How do you use place value to find the values of numbers and describe numbers in different ways?

In this chapter, students will determine whether a group of objects (up to 20) has an odd or even number of members, by pairing objects or counting them by 2s, or by writing an equation to express an even number as a sum of two equal addends.

Students will read and write numbers to 1000 using base-ten numerals, number names, and expanded form. They will also count within 1000, and skip count by 5s, 10s, and 100s.
