25. Lesson 1—Teach 2 + 5 = 7 5 + 2 = 7 Did the sum change when we added in a different order? no

26. Lesson 1—Teach

27. Lesson 1—Check Which numbers are the addends? 4 and 5 4 + 5 = 9

28. Lesson 1—Check Use counters to show the addition is correct. 4 + 5 = 9

29. Lesson 1—Check Write a number sentence that changes the order of the addends. 4 + 5 = 9 5 + 4 = 9

30. Lesson 1—Check Use counters to show the new sentence. 5 + 4 = 9

31. Lesson 1—End

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

59. Lesson 3—End

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

61. Lesson 4—Get Ready 2

62. Lesson 4—Teach Which color has more cubes? red

63. Lesson 4—Teach What is the sum? Start with 3 and then add the yellow cube. 3 + 1 = 4 3 4

64. 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.

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

66. Lesson 4—Check 4 + 2 = __ Circle the greater number. Then count on to add. 6 56 4

67. Lesson 4—Check 3 + 5 = __ Circle the greater number. Then count on to add. 8 678 5

68. Lesson 4—Check Circle the greater number. Then count on to add. 6 + 2 = __ 3 + 4 = __ 5 + 1 = __ 8 7 6

69. Lesson 4—End

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

71. Lesson 5—Get Ready 2

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

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

74. Lesson 5—Teach Use the number line to add. 7 Which addend is greater? 3 + 7 = __

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

76. 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 7. 3 + 7 = __ 10

77. 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. 3 + 7 = __ 10

78. Lesson 5—Check Use the number line to add. 2 + 9 = __ 11

79. Lesson 5—End

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

81. Lesson 6—Get Ready 2 doubles

82. Vocab 3

83. Lesson 6—Get Ready 3

84. Lesson 6—Teach Why is this a doubles fact?doubles The addends are the same. 3 + 3 = 6

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

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

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

88. Lesson 6—Check Find the sums. Circle the doubles facts. 2 + 2 = __ 5 + 1 = __ 0 + 0 = __ 4 + 6 = __ 5 + 5 = __ 3 + 4 = __ 4 6 0 10 7

89. Lesson 6—End

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

91. Lesson 7—Get Ready 2 doubles plus 1

92. Lesson 7—Get Ready 3

93. Lesson 7—Teach 4 + 4 = __8 Find the sum using counters. Add one more counter.

94. Lesson 7—Teach What is the new number sentence? 4 + 5 = 9

95. Lesson 7—Teach How is 4 + 5 different from a doubles fact? 4 + 5 = 9 It has one addend (5) that is greater by 1.

96. Lesson 7—Teach When the addend gets bigger by 1, what happens to the sum? It gets bigger by 1, too. 4 + 5 = 9

97. Lesson 7—Teach Why is 4 + 5 called a doubles plus 1 fact? It is a doubles fact with 1 added to one of the addends. 4 + 5 = 9

98. Lesson 7—Check What doubles fact can be used to find this sum? 6 + 6 = 12 6 + 7 = __

99. Lesson 7—Check Find the sum. Since 6 + 7 is a doubles plus 1 fact, and 6 + 6 = 12, then this sum is 1 more than 12. 136 + 7 = __

100. Lesson 7—End
