Key Concepts

  • Number line representation
  • Addition as moving to the right on a number line
  • Understanding the plus sign (+) and equals sign (=)

Learning Objectives

  • Students will be able to identify and construct a number line.
  • Students will be able to use a number line to solve addition problems with sums up to 10.
  • Students will be able to explain how moving to the right on a number line represents addition.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about numbers and counting. Show the YouTube video "Learn Grade 1 - Maths - Addition Using Number line". Ask them to pay attention to how the number line is used.
  • Building a Number Line (10 mins)
    As a class, create a large number line on the board or using tape on the floor. Start with 0 and go up to 10. Emphasize equal spacing between the numbers. Have students practice counting aloud along the number line.
  • Adding with the Number Line (15 mins)
    Explain that addition means putting numbers together. Demonstrate how to use the number line to add. For example, for 2 + 3, start at 2 and hop 3 spaces to the right. Where you land is the answer! Do several examples together as a class. Use the examples from the video.
  • Practice Time (15 mins)
    Give each student a worksheet with simple addition problems (e.g., 1 + 4, 3 + 2, 5 + 1). Have them use the number line to solve each problem. Walk around the room to provide assistance as needed.
  • Wrap-up (5 mins)
    Review the main concepts of the lesson. Ask students to share what they learned about using a number line for addition. Reiterate that addition means moving to the right on the number line.

Interactive Exercises

  • Number Line Hop
    Use a number line on the floor. Call out addition problems and have students physically hop along the number line to find the answer.
  • Drawing Number Lines
    Have students draw their own number lines and use them to solve addition problems you provide. This reinforces the concept of creating and using a number line independently.

Discussion Questions

  • What is a number line and how can it help us?
  • How does moving to the right on the number line help us add numbers together?
  • Can you think of a time when you might use addition in your everyday life?

Educational Standards

CCSS.Math.Content.1.OA.C.5:Relate counting to addition and subtraction (e.g., by counting on 2 to add 2). 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.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).
