#### MAT-04.OA.03

 MAT-04 Targeted Standards(OA) Domain: Operations and Algebraic ThinkingCluster: Use the four operations with whole numbers to solve problems. MAT-04.OA.03 Solve multistep word problems posed with whole numbers and having whole-numbers answers using the four operations, including problems in which remainders must be interpreted. 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.

## Student Learning Targets:

### Reasoning Targets

• I can interpret the meanings of remainders.
• I can decide if my answer makes sense using mental math, estimation, and rounding strategies.

### Skills (Performance) Targets

• I can solve multistep word problems using the four operations.
• I can represent problems using equations with a letter standing for the unknown quantity.

## Rubric / Proficiency Scale

 Score Description Sample Activity 4.0 Advanced Criteria is Under Development In addition to Score 3.0 performance, the student demonstrates in-depth inferences and applications regarding the more complex content - 3.5 In addition to Score 3.0 performance, the student demonstrates in-depth inferences and applications regarding the more complex content with partial success. 3.0 Student is able to use the four operations to solve multi-step word problems, write equations using a symbol for the unknown, interpret remainders, and use estimation strategies to assess the reasonableness of the answer, without error. I can use any of the four operations to solve two-step 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. I can interpret remainders in problems with division. Student is able to do all tasks without error. 2.5 No major errors or emissions regarding 2.0 content and partial knowledge of the 3.0 content. 2.0 Student is able to use the four operations to solve multi-step word problems, write equations using a symbol for the unknown, interpret remainders, and use estimation strategies to assess the reasonableness of the answers.  Student work contains some errors. I can use any of the four operations to solve two-step word problems, with few mistakes. I can represent the problem using an equation with a letter for the unknown, with few mistakes. I can use mental math, estimation strategies, and rounding to decide in my answer makes sense, with few mistakes. I can interpret remainders in problems with division, with few mistakes. Student has 2 errors in a single problem or has the same error among all problems. 1.5 In addition to 1.0 content, student has partial knowledge of the 2.0 and/or 3.0 content. 1.0 Student is able to demonstrate understanding of solving word problems, but there are multiple errors on more than one problem. I can solve word problems using the four operations, but I may have mistakes. I can write equations that represent the problem, but I may have mistakes. Student shows some understanding of solving problems and writing equations, but strategies lead to incorrect answers. Student is unable to assess the reasonableness of their answers. 0.5 Limited or no understanding of the skill is demonstrated.
