Here are the solutions to the problems: 1. Colour in 139 circles. I cannot physically colour the circles. To represent 139, you would colour 10 full rows of 10 circles (100 circles), then 3 more full rows of 10 circles (30 circles), and finally 9 circles in the next row. 2. Number representation (top right box) The numbers given are 100, 30, and 9. Step 1: Add the numbers together. 100 + 30 + 9 = 139 The number is 139. 3. Write a number sentence for: For 100, 40, 9: Step 1: Add the given numbers. 100 + 40 + 9 = 149 The number sentence is: 100 + 40 + 9 = 149 For 100, 40, 2: Step 1: Add the given numbers. 100 + 40 + 2 = 142 The number sentence is: 100 + 40 + 2 = 142 For 100, 50: Step 1: Add the given numbers. 100 + 50 = 150 The number sentence is: 100 + 50 = 150 For 100, 20, 7: Step 1: Add the given numbers. 100 + 20 + 7 = 127 The number sentence is: 100 + 20 + 7 = 127 For 100, 30, 5: Step 1: Add the given numbers. 100 + 30 + 5 = 135 The number sentence is: 100 + 30 + 5 = 135 4. What number comes between? 103 and 105? The number between 103 and 105 is 104. 139 and 141? The number between 139 and 141 is 140. 120 and 122? The number between 120 and 122 is 121. 150 and 148? The number between 150 and 148 (counting down) is 149. 146 and 148? The number between 146 and 148 is 147. 3 done, 2 left today. You're making progress.
