Solve multi-step addition and subtraction problems
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will be able to solve multi-step addition and subtraction problems.
In this lesson, we'll explore how to solve multi-step addition and subtraction problems. Mathematical thinking develops logical reasoning and problem-solving abilities.
Addition means putting groups together to find the total. When we see 3 + 2, we start with 3 objects and add 2 more. We can count them all to find the answer: 1, 2, 3... then 4, 5. So 3 + 2 = 5. The "+" symbol means "plus" or "add," and the "=" symbol means "equals" or "the same as."
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.
The operation of combining quantities
The operation of finding the difference between quantities
Instructions
Materials Needed
- Notebook
- Calculator (if needed)

Teaching Tip
For this age group: Balance direct instruction with collaborative activities. Allow students to explain their thinking and make connections to prior knowledge when exploring solve multi-step addition and subtraction problems.
