Long Division Lesson Plan for 4th Grade

Learning objective

• Practice division facts written in the standard long division format
• Apply familiar facts using the long division bracket and notation
• Build comfort with long division layout using known fact fluency

Materials

• 2-digit divided by 1-digit (no remainder) - Bike
• Division facts (long division format)
• 2-digit by 1-digit, no remainder
• 2-digit by 1-digit, remainder possible
• 3-digit by 1-digit, no remainder
• 3-digit by 1-digit, remainder possible
• Pencils, and whiteboard space for the modeled examples

Lesson steps

1. 1. Warm up together (5 min)

   Open with three quick mental problems on long division, hands down, answers called out together. You are checking who has recall and who is reconstructing every time.

2. 2. Model it (I do) (10 min)

   Solve two long division problems on the board, narrating the step most students skip. Then solve one wrong and ask the class to find where it broke.

3. 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. 4. Independent practice (you do) (15 min)

   Hand out "2-digit divided by 1-digit (no remainder) - Bike". 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. 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 long division retaught in a small group before the class moves on.

Differentiation

Extra support. Students who stall: pull them into a small group and rebuild long division 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 long division 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 long division.
