Lesson Plan: Hibernation Math (Gr 1)

Subject: Math
Grade: 1
Lesson Objective: To use addition and subtraction to solve word problems
Common Core Standard: CCSS.MATH.CONTENT.1.OA.A.2- Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
Materials:
Starter:
Say:
- Why do we add numbers? (Allow the students to answer.)
Main:
Say:
- We add numbers so that we can figure out how many of something we have. If we did not add numbers, we would end up counting a lot. For example, instead of adding 2 pieces of candy to 4 pieces of candy and getting 6, you would have to count every piece of candy. (Write this problem on the board- 2 + 4 =6. You can use your fingers to show them adding.)
- When figuring out an addition problem, it is a good idea to draw a picture to help you. If you were adding 1 + 2, you could draw one circle and then two more circles. (Demonstrate this)
- You would then be able to count all of the circles by pointing to each one as you count. You would see that there are 3 circles. So, you know the answer to 1 + 2 is 3.
- Today, you are going to be solving word problems.
- To solve a word problem, you first need to figure out what numbers you need to be adding.
- After you understand what you are supposed to do, you should write the addition problem down. Next, you should draw a picture to help you solve the problem or to show how you solved the problem.
- For each of the three word problems, make sure that you write down the addition problem and then draw a picture. When you are done, we will go over all of the answers.
- Does anyone have any questions?
Feedback:
Say:
- Who would like to share your answers? (Allow the students to share.)
