# Lesson Plan: Stars (Math - Grade 1)

Subject:  Math

Lesson Objective: To use addition to solve problems

Common Core StandardCCSS.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.

Main:

Say:

• When you add numbers, you are putting them together.  For example, if you are adding 1 + 2, you are putting one of something and two of something together.  What answer would you get?  (Allow the students to answer.  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 addition problems about stars.
• To figure out the answer to the addition problem, you should draw a picture.  You can draw circles or stars, whichever is easier for you.  After you draw a circle or star, you can count the total number.  This is the answer to your addition problem.
• For each of the problems, make sure that you draw a picture and then write the answer down.  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.)
