Description
Solving for a missing addend can be a tough concept for kids to grasp. These robots are here to help and are need of some help themselves! In this activity pack robots are in need of some help to find their missing parts. Students will practice using part-part-whole to solve for those missing parts (or addends).
Included in this activity pack:
- Missing parts worksheet (front and back)
- Using subtraction to solve missing parts worksheet (front and back)
- Part-Part-Whole Robot activity mat
- Spinners for determining Whole and Part numbers
- A center activity for continued practiced

CCSS1.OA.B.3
Apply properties of operations as strategies to add and subtract. If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
CCSS1.OA.B.4
Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
CCSS1.OA.C.6
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
