Addition Subtraction Lesson Plan for 5th Grade
A ready-to-teach addition subtraction lesson for 5th Grade, built around multi-digit addition and subtraction, decimal addition and subtraction, estimation, missing addend and subtrahend problems. Print the plan, print the practice pages, and you are set.
Approximately 45 minutes
Learning objective
- Find the missing addend when the sum of three terms is known
- Apply inverse operations to solve for an unknown in 3-term sums
- Practice mental strategies for missing addend equations
Materials
- Adding 4 numbers in columns
- Adding 5 numbers in columns
- Adding large numbers, 4 addends
- Adding large numbers, 6 addends
- 4 operations - mixed word problems
- Missing addends (3 terms)
- Pencils, and whiteboard space for the modeled examples
Lesson steps
1. Warm up together (5 min)
Open with a quick count-around or number talk that touches addition subtraction. Ask students where they have seen addition subtraction outside of math class. You are listening for who already has the vocabulary and who does not, so keep it light and let several students answer.
2. Model it (I do) (10 min)
Work two examples of addition subtraction on the board, thinking out loud the whole way. Say the quiet parts: what you notice first, which step you do next, and why. Deliberately make one small error on the second example and let the class catch it.
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 "Adding 4 numbers in columns". 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 addition subtraction retaught in a small group before the class moves on.
Differentiation
Extra support. Students who stall: pull them into a small group and rebuild addition subtraction 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 addition subtraction 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 addition subtraction.
