Georgia 5.NR.5

5.NR.5 is a Georgia mathematics standard. These are the expectations under it.

• 5.NR.5.1

  Write, interpret, and evaluate simple numerical expressions involving whole numbers with or without grouping symbols to represent actual situations.

01

What Students Need to Do

Students turn real situations into expressions using numbers, operation symbols, and grouping symbols. They explain what each part means and find the expression’s value using the correct operation order.

02

What Mastery Looks Like

A student writes an expression that matches the quantities and relationships in a problem. The student evaluates it accurately and explains what each number and operation represents.

03

Common Misconceptions

Students may add an equal sign when only an expression is needed. They may work strictly left to right, ignore grouping symbols, or choose an operation that does not match the situation.

04

How to Assess It

Give this exit ticket: “Each supply bag holds 8 pencils and 2 erasers. Write and evaluate an expression for the total items in 3 bags. Explain the parentheses.”

1. 01

   Give pairs 3 cups with 4 red and 2 blue counters in each, then have them write and evaluate a matching expression.

2. 02

   Ask students to write different stories for 3 × (4 + 2) and 3 × 4 + 2, then compare the meanings.

3. 03

   Use a card sort with situation cards, expression cards, and value cards, and have teams match each complete set.

4. 04

   Give students a simple snack menu and budget, then ask them to write and evaluate an expression for one group order.

• 6.PAR.6.3

  Write and read expressions that represent operations with numbers and variables in realistic situations.

• 6.PAR.6.1

  Write and evaluate numerical expressions involving rational bases and whole-number exponents.

• 6.PAR.6

  Identify, write, evaluate, and interpret numerical and algebraic expressions as mathematical models to explain relevant situations.
