Introduction—End

Lesson 1—Get Ready 1 I will add in any order.

Lesson 1—Get Ready 2 addend

Vocab 1

Lesson 1—Get Ready 3

Lesson 1—Teach Create an addition problem using 2 blue and 5 red connecting cubes. What are the two addends?addends 2 and 5

Lesson 1—Teach = 7 What number sentence do the cubes show?

Lesson 1—Teach = 7 Move the blue cubes to the other end. What number sentence do the cubes show now?

Lesson 1—Teach How are the number sentences different? = = 7 The addends are in a different order.

Lesson 1—Teach = = 7 Did the sum change when we added in a different order? no

Lesson 1—Teach

Lesson 1—Check Which numbers are the addends? 4 and = 9

Lesson 1—Check Use counters to show the addition is correct = 9

Lesson 1—Check Write a number sentence that changes the order of the addends = = 9

Lesson 1—Check Use counters to show the new sentence = 9

Lesson 1—End

Lesson 2—Get Ready 1 I will count on to add.

Lesson 2—Get Ready 2 count on

Vocab 2

Lesson 2—Get Ready 3

Lesson 2—Teach Model the problem with connecting cubes = __

Lesson 2—Teach What are the addends? 3 and = __

Lesson 2—Teach Which number is less? = __

Lesson 2—Teach Which number is greater? = __

Lesson 2—Teach When you add these numbers by counting on, which number should you start from? counting on = __

Lesson 2—Teach Why is it easier to begin with the greater number? You do not have to count on as many numbers = __

Lesson 2—Teach How many cubes will you count on? = __ 3

Lesson 2—Teach What is the sum? = __

Lesson 2—Check Start with the greater number. Count on to add = __

Lesson 2—Check Start with the greater number. Count on to add = __

Lesson 2—Check = __ = __ = __ Start with the greater number. Count on to add.

Lesson 2—End

Lesson 3—Get Ready 1 I will use models to act out and solve problems.

Lesson 3—Get Ready 2

Lesson 3—Teach 49

Lesson 3—Teach What do I need to find? Circle the question. 50

Lesson 3—Teach How will I solve the problem? 51 Act it out.

Lesson 3—Teach Should you add or subtract to find how many cans Marcy collected? add

Lesson 3—Teach How many cubes should you show for Sam? 6 cans

Lesson 3—Teach How many more cubes will you show for Marcy? 4 cans

Lesson 3—Teach How many cans did Marcy collect? = 10 cans

Lesson 3—Teach Look back. Does my answer make sense? =

Lesson 3—Check Carlos has 6 model planes. His sister gives him 4 more. How many planes does Carlos have now? 10 planes

Lesson 3—End

Lesson 4—Get Ready 1 I will add 1, 2, or 3.

Lesson 4—Get Ready 2

Lesson 4—Teach Which color has more cubes? red

Lesson 4—Teach What is the sum? Start with 3 and then add the yellow cube = 4 3 4

Lesson 4—Teach Why did we begin with the three red cubes? 3 is the greater number, and we only had to count on 1 instead of starting with 1 and counting on 3.

Lesson 4—Teach Adding 1 is just finding the next number.

Lesson 4—Check = __ Circle the greater number. Then count on to add

Lesson 4—Check = __ Circle the greater number. Then count on to add

Lesson 4—Check Circle the greater number. Then count on to add = __ = __ = __ 8 7 6

Lesson 4—End

Lesson 5—Get Ready 1 I will use a number line to add.

Lesson 5—Get Ready 2

Lesson 5—Teach Start at 4. 3 jumps How many jumps to 7?

Lesson 5—Teach Start at 2. 4 jumps How many jumps to 6?

Lesson 5—Teach Use the number line to add. 7 Which addend is greater? = __

Lesson 5—Teach How many will you count on from 7? 3 What is the sum? = __ 10

Lesson 5—Teach Why is it best to count on from 7? It is faster to start with the greater number (7) and count on only 3 than to start with 3 and count on = __ 10

Lesson 5—Teach How does a number line help you find the sum of two numbers? You can start at the greater number and point to the numbers as you count on or add = __ 10

Lesson 5—Check Use the number line to add = __ 11

Lesson 5—End

Lesson 6—Get Ready 1 I will add using doubles.

Lesson 6—Get Ready 2 doubles

Vocab 3

Lesson 6—Get Ready 3

Lesson 6—Teach Why is this a doubles fact?doubles The addends are the same = 6

Lesson 6—Teach What is the related subtraction fact? 6 – 3 = = 6

Lesson 6—Teach How are the number sentences the same? They use the same numbers = 6 6 – 3 = 3

Lesson 6—Teach How are they different? One is an addition fact and one is a subtraction fact = 6 6 – 3 = 3

Lesson 6—Check Find the sums. Circle the doubles facts = __ = __ = __ = __ = __ = __

Lesson 6—End

Lesson 7—Get Ready 1 I will add using doubles plus 1.

Lesson 7—Get Ready 2 doubles plus 1

Lesson 7—Get Ready 3

Lesson 7—Teach = __8 Find the sum using counters. Add one more counter.

Lesson 7—Teach What is the new number sentence? = 9

Lesson 7—Teach How is different from a doubles fact? = 9 It has one addend (5) that is greater by 1.

Lesson 7—Teach When the addend gets bigger by 1, what happens to the sum? It gets bigger by 1, too = 9

Lesson 7—Teach Why is called a doubles plus 1 fact? It is a doubles fact with 1 added to one of the addends = 9

Lesson 7—Check What doubles fact can be used to find this sum? = = __

Lesson 7—Check Find the sum. Since is a doubles plus 1 fact, and = 12, then this sum is 1 more than = __

Lesson 7—End

Lesson 8—Get Ready 1 I will choose a strategy to solve problems.

Lesson 8—Get Ready 2

Lesson 8—Teach What do I need to find? Circle it.

Lesson 8—Teach How will I solve the problem?

Lesson 8—Teach

One way is to act it out. Use a counter for each feather.

Lesson 8—Teach How many feathers does Amy have?

Lesson 8—Teach How many feathers does Bill have?

Lesson 8—Teach How many more feathers does Bill need? 2 feathers

Lesson 8—Teach Look back. Does my answer make sense? = yes

Lesson 8—Check Choose a strategy. Solve. Jamal collected 8 sea shells. His sister collected 3 sea shells. How many more sea shells does his sister need to collect to have as many as Jamal? 5 sea shells

Lesson 8—End

Chapter Review 1 ____________ are two addends that are the same number. ____________ are the numbers being added together. addends doubles Complete the sentences. Doubles Addends

Chapter Review 2 Circle the greater number. Then count on to add = __ = __ = __ = __9

Chapter Review 3 Find the sum. Circle the doubles facts = __ = __ = __ = __9
