Chapter 3:
Essential Question: 
 How can you use patterns and strategies to find sums and differences for basic facts?

In this chapter, students will add and subtract within 20 using mental strategies.  They will represent and solve problems involving addition and subtraction within 100 to solve one and two step word problems involving situations of adding  to, taking from, putting together, taking apart, and comparing with unknowns in all positions.  Finally, students will work with equal groups of objects to gain foundations for multiplication.

Chapter 2:
Essential Question:
How can you use place value to model, write, and compare 3-digit numbers?

In this chapter, students will understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones.  They will read and write numbers to 1000 using base-ten numerals, number names, and expanded form.  Students will mentally add 10 or 100 to a given number 100-900, and mentally subtract 10 or 100 from a given number 100-900.  Students will also compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using symbols to record the results of comparisons.

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.
