*For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.*

**Subject Area:**Mathematics

**Grade:**5

**Domain-Subdomain:**Operations and Algebraic Thinking

**Cluster:**Level 1: Recall

**Cluster:**Write and interpret numerical expressions. (Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

**Date Adopted or Revised:**02/14

**Date of Last Rating:**02/14

**Status:**State Board Approved

**Assessed:**Yes

**Assessment Limits :**

Expressions may contain whole numbers or fractions with a denominator of 10 or less. Expressions may not include nested parentheses. Multiplication cross symbol is the only acceptable symbol for multiplication. The multiplication dot (•) may not be used. When grouping symbols are part of the expression, the associative property or distributive property must be found in the expression.**Calculator :**No

**Context :**No context

Students are asked to write an expression requiring more than one operation and the use of parentheses to model a word problem.

Students are asked to model an expression that is a multiple of a sum and to compare the expression to the sum.

Students are presented with a verbal description of a numerical expression and are asked to write the expression and then compare it to a similar expression.

## Problem-Solving Tasks

This task asks students to exercise both of these complementary skills, writing an expression in part (a) and interpreting a given expression in (b). The numbers given in the problem are deliberately large and "ugly" to discourage students from calculating Eric's and Leila's scores. The focus of this problem is not on numerical answers, but instead on building and interpreting expressions that could be entered in a calculator or communicated to another student unfamiliar with the context.

Type: Problem-Solving Task

The purpose of this task is to help students see that 4×(9+2) is four times as big as (9+2). Though this task may seem very simple, it provides students and teachers with a very useful visual for interpreting an expression without evaluating it because they can see for themselves that 4×(9+2) is four times as big as (9+2).

Type: Problem-Solving Task

The purpose of this task is to generate a classroom discussion that helps students synthesize what they have learned about multiplication in previous grades. It builds on 3.OA.5 Apply properties of operations as strategies to multiply and divide and 4.OA.1 Interpret a multiplication equation as a comparison.

Type: Problem-Solving Task

This problem allows student to see words that can describe the expression from part (c) of "5.OA Watch out for Parentheses." Additionally , the words (add, sum) and (product, multiply) are all strategically used so that the student can see that these words have related meanings.
