MAT03 Targeted Standards (OA) Domain: Operations and Algebraic Thinking Cluster: Solve problems involving the four operations, and identify and explain patterns in arithmetic. Multiply and divide within 100.
MAT03.OA.08 Solve twostep word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity; assess the reasonableness of answers using mental computation and estimation strategies including rounding.
The size of the numbers should be limited to related 3rd grade standards (3.OA.7 and 3.NBT.2). Adding and subtracting numbers should include numbers within 1000 and multiplying and dividing numbers should singledigit factors and products less than 100.
Student Learning Targets:
Reasoning Targets
I can judge the reasonableness of my answer.
Skills (Performance) Targets
I can use any of the four operations to solve twostep word problems.
I can represent the problem using an equation with a letter for the unknown.
I can use mental math, estimation strategies, and rounding to decide in my answer makes sense.
