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.

Common mistakes to watch for

✗ Adding before multiplying (2 + 3 × 4 = 20).
✓ The answer key shows 2 + 12 = 14 — compare where the steps diverged. The "underline the multiplication" trick prevents this.
✗ Forgetting left-to-right within the same tier.
✓ In these worksheets every expression has exactly one multiplication, so left-to-right within a tier is not tested yet — a deliberate ramp into harder sheets.

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.
