Number Concepts
In Chapter 1 we 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.  
** write an equation to express an even number as a sum of two equal addends.
** count within 1000; skip count by 5s, 10s, and 100s.
** read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
