Description: Students will review sums through 12 while finding the missing addend in a number sentence by dividing a group into two parts. There are 22 cards. The students will look at a number sentence with a missing addend. They will see a line of turkeys. The number of turkeys shown is equal to the sum. This deck will help the students understand how two parts (addends) equal the whole (sum). They will work with a part and a whole to find the missing part. How to Use the Deck: - The students will drag a bar to divide the group of turkeys using the known addend from the number sentence. - They will use the bar to separate the line of turkeys so the number of turkeys for an addend is on one side and the other addend on the other side. - They will type the missing addend to complete the number sentence. - Recorded instructions are provided to work through a sample problem and for the first problem. - The number sentence is large and contains a box for the missing addend. The students will type the addend in the box. "Boom™ is the trademark of Boom Learning.
