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.)
