Grade 4 G/T Expressions and Equations

5.OA.1

About the Math

Full Standard

Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.

 

Learning Targets (I can)

  • Determine how parentheses and brackets affect expressions.
  • Use parentheses and brackets to group an expression within a multi-step expression.
  • Evaluate expressions with parentheses and brackets.

 

About the Math

  • Determine how parenthesis and brackets affect expressions.
  • Use parenthesis and brackets to group an expression within a multi-step expression.
  • Evaluate expressions with parenthesis and brackets.

Grouping symbols and the order of operations in general affect expressions. Students should learn about this by evaluating the same expression in different ways (correctly and incorrectly) to determine why the order of operations matters. 

Order of Operations When evaluating expressions, it is necessary to use the order of operations.
The order of operations is a convention that standardizes how we evaluate expressions. Students need to discover that the following is the order:

  1. Grouping symbols
  2. Exponents
  3. Multiplication and Division (left to right)
  4. Addition and subtraction (left to right)

Essential vocabulary for this standard includes: parenthesis, expression, evaluate, bracket, and variable. Visit the online dictionary Links to an external site. or visual math dictionary Links to an external site. vocabulary support.

Instructional Tasks

TASKS

These tasks can be used with small group or whole group instruction.

  • Ty says that 16 - (4 + 4) = 8. Jade says it equals 12. Who do you agree with?
  • Do these two equations have the same solution? Why or why not? (18 + 5) x 2 AND 18 + (5 x 2)
  • Given 12 ÷ 4 + 2, where should the parentheses be in this equation to make it equal 2?
  • Write a numerical expression with at least two operations so that when evaluated it equals 18.
  • Why do we need order of operations? What might happen if we didn't have order of operations?

 

SLIDE-BASED TASKS 

 These links are HCPSS created instructional tasks. These tasks are provided in Google slides. These tasks should be used for inspiration and resources, but instruction should start with students having the opportunity to engage with the math first (often involving physical and/or visual models) followed by discussion and explicit instruction to ensure student understanding.

Assessment

Learning Targets

rubric

  • Determine how parentheses and brackets affect expressions.
  • Use parentheses and brackets to group an expression within a multi-step expression.
  • Evaluate expressions with parentheses and brackets.

 

Learning targets identify what students should be able to do. The resources below can be used to measure student understanding of the standard. This rubric can be applied to tasks and observations for assessment and/or grading.
