Key Concepts

  • Addition
  • Counting
  • Number combinations

Learning Objectives

  • Students will be able to add three single-digit numbers together.
  • Students will be able to use counting to find the sum of three numbers.
  • Students will be able to solve simple addition problems involving three numbers.

Educator Instructions

  • Introduction (5 mins)
    Start by asking students if they like goldfish or other pets. Introduce the idea of counting pets to find the total number. Explain that today we will learn how to add three groups of things together, just like counting different bowls of goldfish.
  • Video Viewing (7 mins)
    Play the "Learn Grade 1 - Maths - Addition of Three Digit Numbers" video. Encourage students to count along with the video and observe how the numbers are added.
  • Practice Together (8 mins)
    After the video, write a few addition problems on the board, such as 2 + 1 + 3 = ?. Ask students to count on their fingers or draw pictures to find the answer. Work through each problem together as a class, explaining each step.
  • Independent Practice (10 mins)
    Give students a worksheet with similar addition problems. Have them work independently to solve the problems. Circulate to provide assistance as needed.

Interactive Exercises

  • Counting Objects
    Provide students with small objects like blocks or counters. Give them problems like: "Put 2 blocks, then 3 blocks, then 1 block together. How many blocks do you have in all?"
  • Drawing Pictures
    Have students draw pictures to represent addition problems. For example, for the problem 1 + 4 + 2, they could draw 1 circle, then 4 circles, then 2 circles, and then count all the circles to find the answer.

Educational Standards

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). 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.
