Introduction:

In this lesson, we are going to be learning about addition and subtraction. Math is an important part of our lives and addition and subtraction are the basics of math. We can use addition and subtraction to solve challenging problems, which is really cool! Let’s get started!

Lesson Outline:

1. Introduce the concepts of addition and subtraction. - Watch a video to help explain the basics: https://www.youtube.com/watch?v=Nnnzz0r0KQQ

2. Introduce basic addition and subtraction facts. - Have students practice with worksheets. Here is a sample worksheet: https://www.math-drills.com/addsub/adding_subtracting_three_numbers_practice.pdf

3. Introduce the concepts of carrying the 1 and regrouping. - Show the students how to carry the 1 and regroup using a worksheet. Here is a sample worksheet: https://www.k5learning.com/sites/all/files/worksheets/grade-3- Carry-1-subtract-1-worksheet-4.pdf

4. Practice more complicated addition and subtraction. - Watch a video and use worksheets: Video: https://www.youtube.com/watch?v=gphZaagXszs Worksheet: https://www.education.com/worksheet/article/addition-subtraction/?grade=3

Questioning: The teacher should ask questions throughout the lesson such as: - What do we use addition and subtraction for? - How do we solve for carrying the 1 and for regrouping? - What strategies can we use for more complicated addition and subtraction equations?

Assessment: Assess student understanding by having them answer questions about what they have learned, or having them solve complicated addition and subtraction word problems.

Differentiation: Allow students to work at their own pace by breaking them up into groups and having them answer different worksheets of varying difficulty.

Plenary: Have the students present the solutions to a few examples of more complicated addition and subtraction equations, and help them explain their understanding of the concepts learned in the lesson.
