Key Concepts

  • Addition
  • Counting
  • Word Problems

Learning Objectives

  • Students will be able to add three whole numbers with a sum less than or equal to 20.
  • Students will be able to solve word problems involving the addition of three numbers.
  • Students will be able to count and identify quantities of objects up to 20.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about addition. Show them the Boddle Learning video. Tell them that they will be learning how to add three numbers together.
  • Counting Fruits (10 mins)
    Watch the first part of the video where Irene counts the fruits. Pause the video after each type of fruit is counted. Ask the students to write down the number of apples, oranges, and strawberries. Then, have them add the numbers together to find the total number of fruits. Discuss the answer as a class.
  • Toy Counting (10 mins)
    Watch the next part of the video where Irene counts her toys. Again, pause the video after each type of toy is counted. Have students write down the number of cars, dolls, and balls. Have them add the numbers to find the total number of toys. Share answers as a class.
  • Flower Counting (10 mins)
    Watch the final part of the video about the flowers. Have students follow along with the addition problem as it is shown in the video. Then, create similar flower-addition problems on the board and have students solve them independently or in small groups.
  • Wrap-up (5 mins)
    Review the main concepts of the lesson. Ask students to share what they learned and how they can use addition in their daily lives.

Interactive Exercises

  • Fruit Basket Addition
    Provide students with pictures of different fruits (apples, bananas, grapes). Assign a number to each fruit (e.g., apple = 2, banana = 3, grapes = 1). Have students create their own fruit baskets with different combinations of fruits and add the numbers together to find the total value of their basket.
  • Toy Store Math
    Set up a pretend toy store with different toys (cars, dolls, blocks). Assign a number value to each toy. Give students a certain amount of pretend money and have them choose three toys to buy. They need to add up the cost of the three toys to see if they have enough money.

Discussion Questions

  • Can you think of a time when you needed to add more than two things together?
  • What are some different ways we can add numbers together to make it easier?
  • How does knowing how to count help us add?

Educational Standards

CCSS.Math.Content.1.OA.A.1:Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. 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. CCSS.Math.Content.1.OA.C.6:Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
