Lesson steps

1. Warm up together (5 min)
Open with three quick mental problems on multiply in columns, 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 multiply in columns 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 "2-digit by 1-digit". 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 multiply in columns retaught in a small group before the class moves on.

Differentiation

Extra support. Students who stall: pull them into a small group and rebuild multiply in columns 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 multiply in columns 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 multiply in columns.
