Copyright © 2016 Melanie LiCausi All Rights Reserved Name ___________________ Date (Pretest)__________ (Posttest) __________ Assessment Operations and Algebraic Thinking 1.OA.3. Apply properties of operations as strategies to add and subtract. Examples: 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.) I understand that adding or subtracting zero doesn’t change a number. a) 12 + 0 = _________ b) 15 - 0 = _________ c) 0 + 4 = _________ d) 9 - 0 = _________ e) 10 + 0 = _________ f) 20 - 0 = _________ Copyright © 2016 Melanie LiCausi All Rights Reserved Name ___________________ Date (Pretest)__________ (Posttest) __________ Assessment Operations and Algebraic Thinking 1.OA.3.
