Mental Multiplication Lesson Plan for 4th Grade
A ready-to-teach mental multiplication lesson for 4th Grade. Everything below is classroom-tested structure: an objective, a 45-minute sequence, a way to check who got it, and 6 printable practice pages.
Approximately 45 minutes
Learning objective
- Recall multiplication facts for all tables from 2 through 10
- Apply fast recall of products to complete table exercises fluently
- Build automatic fact fluency across all multiplication tables to 10
Materials
- Multiplication tables 2-10, missing factor
- Multiplication tables 2-12, missing factor
- Commutative property
- Associative property
- Distributive property
- Multiply 1-digit by whole tens
- Pencils, and whiteboard space for the modeled examples
Lesson steps
1. Warm up together (5 min)
Open with three quick mental problems on mental multiplication, hands down, answers called out together. You are checking who has recall and who is reconstructing every time.
2. Model it (I do) (10 min)
Solve two mental multiplication problems on the board, narrating the step most students skip. Then solve one wrong and ask the class to find where it broke.
3. Practice together (we do) (10 min)
Work three more problems as a class. Ask a different student to supply each step rather than the whole answer. If a step stalls, drop back to concrete objects or a drawing before moving on.
4. Independent practice (you do) (15 min)
Hand out "Multiplication tables 2-10, missing factor". Students work independently while you circulate. Note who is fluent, who is counting on fingers, and who has not started, because that grouping drives tomorrow's small group.
5. Close the loop (5 min)
Pull the class back. Ask one student to explain a problem they got right and one to name something that is still confusing. End on the confusion, not the success, so students learn that naming a gap is normal.
Check for understanding
Collect the practice pages and sort them into three piles: fluent, developing, and not yet. Any student in the third pile needs mental multiplication retaught in a small group before the class moves on.
Differentiation
Extra support. Students who stall: pull them into a small group and rebuild mental multiplication with concrete materials or a simpler text before asking for the written work again. Do not send the page home as homework, it will just rehearse the misunderstanding.
Extension. Students who finish early: ask them to write their own mental multiplication problem for a partner to solve, then check the partner's work. Creating a problem is harder than solving one and it surfaces whether they really understand mental multiplication.
