- explain (how properties of operations help solve addition and subtraction problems) #dok3
Learning Targets
- I can show how to use the properties of operations when adding or subtracting two or three numbers. #dok2
- I can use properties of operations to add or subtract numbers in any order. #dok2
- I can recognize and explain how the order of numbers may not change the sum when adding (commutative property). #dok2
- I can explain how I use properties like the commutative and associative properties to add or subtract. #dok3
- I can solve addition and subtraction problems by using properties of operations. #dok2
Big Ideas
- Mathematical properties such as the commutative and associative properties can help make addition and subtraction easier.
- Using properties of operations allows numbers to be added or subtracted in different ways to simplify problem solving.
Essential Questions
- How can you use properties of operations to help you add or subtract numbers?
- Why does the order that you add numbers sometimes not matter?
- What is the commutative property and how does it help in solving problems?
- How do properties of operations make math problems easier to solve?
- Can you find more than one way to solve an addition or subtraction problem using properties of operations?
