Lesson Plan: Snowflakes Math (Gr1)

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:
- What is addition? (Allow the students to answer.)
Main:
Say:
- Addition is adding numbers or putting them together. Why would you need to add? (Allow the students to answer.)
- We might need to add to figure out how many pieces of candy you were given, how many toys you have or how many points you earned in a game.
- Addition helps us so that we do not need to count all of the time. For example, instead of adding 2 points to 3 points and getting 5, you would have to count every point you earned. (Write this problem on the board- 2 + 3 =5. 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. You do this by reading the addition word problem. The word problem will give you a scenario. There will be a question at the end that uses words such as all together or how many total. This means that you should add.
- After you understand what you are supposed to do, you should write the addition problem down and draw a picture to help you solve 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.)
