5 days · 15 printables (7 unique worksheets) · ✅ Answer key on every worksheet
Day 1 — Start: factors and multiples
Tap any worksheet to open it and print.
Five minutes of division facts to see who is fluent and who needs a fact card on their desk this week.
Lesson / classworkFactor PairsBuild the idea that multiplication and division are two views of the same factor pair. Model the first few with arrays on the board.
HomeworkMultiples, Factors, Prime, and CompositeExtends tonight what we started with factor pairs. Tell students it is fine to list factors in the margin to decide prime or composite.
Day 2 — Practice: multiplying big numbers
Tap any worksheet to open it and print.
Same sheet as Monday, but time it and have students beat their own score.
Lesson / classworkBig MultiplicationWork the first half together with area models before letting students try the standard algorithm on the rest.
HomeworkBig MultiplicationSend home the problems you did not reach in class. Ask families to check that place-value zeros are showing in each partial product.
Day 3 — Practice: long division
Tap any worksheet to open it and print.
Quick factor recall primes students for the divide, multiply, subtract rhythm coming next.
Lesson / classworkLong Division Step by StepGo step by step and have students say each step aloud. Expect a slow first page; accuracy matters more than speed today.
HomeworkDivision Facts PracticeFact practice at home, since shaky facts are the number one reason long division breaks down.
Day 4 — Stretch: order of operations
Tap any worksheet to open it and print.
Mixed addition and subtraction to keep regrouping sharp before a multi-step day.
Lesson / classworkPEMDAS PowerStretch sheet from Grade 5. Stick to expressions with multiplication, division, and one set of parentheses, and let strong students push further.
HomeworkLong Division Step by StepA second pass at long division now that the steps have had a night to settle.
Day 5 — Review: mixed operations
Tap any worksheet to open it and print.
Final timed round for the week. Have students compare with Monday to see their growth.
Lesson / classworkMultiples, Factors, Prime, and CompositeRevisit in class what students did as Monday homework, and use partner checks to clear up prime versus composite mix-ups.
HomeworkBig MultiplicationWeekend review of the big skill of the week. A good sheet to glance over before starting next week.
Classroom use: teachers may print and copy these worksheets for their own students — homework, classwork, centers, sub plans, all fair game.
