Grade 3 Mixed Operations Worksheets
At grade 3, mixed operations means all four operations, with two-step expressions introduced. Below are five worksheets on it — one per format — each in Set A, B and C with keys.
What the grade 3 mixed operations sheets cover
Grade 3 mixed operations comes in five formats (problem counts in brackets): drill (20, straight practice), timed drill (72, timed fluency), missing number (24, find the blank), mixed review (30, mixed shapes), and word problems (8, stories). Set A uses numbers from 1 to 838, 18 column problems that regroup, and 24 fill-in blanks. Problem types: mixed multiplication and division facts, mixed addition and subtraction facts, and all four operations, plus one more. All five come as Sets A, B and C with answer keys, 154 problems per set from 8 to 72 a sheet. From the Set A drill, problem 7: "9 × 2" (answer 18). Common Core: 3.OA.7 and 3.OA.8.

Across the five sheets the generator draws on mixed multiplication and division facts, mixed addition and subtraction facts, all four operations, and two-step expressions. The pages are tagged to Common Core 3.OA.7 and 3.OA.8, and each tag links to the standards index.
Mixed operations continues at grade 1, grade 2, grade 4, grade 5, and grade 6, so a student who finishes the grade 3 sheets can move up without changing topic.
Start with the grade 3 mixed operations drill to see whether the method is in place, use the timed drill only once accuracy is there, and save the word problems for the point where the student can compute without thinking about it.
