Order of Operations Worksheets — PEMDAS Practice
Order of operations is the rulebook that makes math unambiguous. These worksheets start with the simplest conflict — addition vs. multiplication in one expression — so students master "multiply before you add" before brackets and exponents arrive. The answer key shows the intermediate step so students can see where they diverged.

Teaching tips for order of operations
- •Teach PEMDAS as a memory anchor, but emphasize that multiplication/division and addition/subtraction are done left to right within their tier.
- •On a simple a + b × c problem, ask students to underline the multiplication first — a visual cue that it happens before the addition.
- •Have students write the intermediate value: 2 + 3 × 4 → 2 + 12 → 14. Seeing the middle step written down builds the habit.

Grade & standards alignment
These order of operations worksheets target the Grades 5–6 band of the Common Core State Standards for Mathematics (CCSSM). The relevant CCSS math domains are:

The CCSSM are public, open-license standards; this alignment is provided for planning and is not an official endorsement by the standards authors.
How these worksheets are built (accuracy & trust)
- •Problems are generated by a deterministic engine using exact integer and rational arithmetic — answers are reduced to lowest terms and never rely on floating-point rounding, so they match the matching UnitFig converter.
- •Grade presets follow the CCSSM progression above; pick a grade to get age-appropriate number ranges.
- •Content is reviewed for accuracy and refreshed each year (2026). Worksheet copy and examples are original and written for classroom use.
Safe for classrooms — zero data collection
UnitFig collects no personal information from children or any visitor. Worksheets run entirely in the browser: no account, no name or email, and student answers never leave the device. We follow a COPPA-aligned, zero-collection design so teachers and parents can use these sheets without a signup wall or privacy concern. See our Privacy Policy.
Frequently Asked Questions
What grade is order of operations taught?
Simple "multiply before you add" appears in grade 3–4, and full PEMDAS including parentheses and exponents is formalized in grade 5 (5.OA.A.1) and grade 6 (6.EE.A.1).
Why only addition and multiplication?
This sheet isolates the single most common mistake — adding before multiplying — so students master it before parentheses and exponents add more moving parts.
Is there a harder version?
Yes — increase the number range to make the arithmetic harder while the rule stays the same, then move to sheets with parentheses as the next step.
