Subject:  Math

Grade: 1

Lesson Objective: To use addition and subtraction to solve word 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.




  • What is addition?  (Allow the students to answer.)



  • 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?



  • Who would like to share your answers?  (Allow the students to share.)
