Add three numbers

Key points :

Understanding Addition:

  • Explain that addition means putting together or combining numbers.
  • Use simple language to describe what it means to add.

Concept of Three Numbers:

  • Introduce the concept of adding three numbers by using examples (e.g., 2 + 3 + 4).
  • Emphasize that we can add them in any order (commutative property).

Visual Aids:

  • Use objects (like counters, blocks, or fruits) to visually demonstrate adding three numbers.
  • Draw pictures or use number lines to illustrate the addition process.

Step-by-Step Process:

  • Show how to add numbers step-by-step:
    1. Add the first two numbers.
    2. Add the result to the third number.
  • Example: For 2 + 3 + 4:
    • Step 1: 2 + 3 = 5
    • Step 2: 5 + 4 = 9

Learn with an example

🖊️Add: 2 + 5 + 2 =

Hint: Start by adding a double.

First, add the doubles 2 and 2 to make 4:

2 + 5 + 2 = ?

4 + 5 = ?

Now add 4 and 5:

4 + 5 = 9

The sum is 9.

🖊️Add: 1 + 2 + 1 =

Hint: Start by adding a double.

First, add the doubles 1 and 1 to make 2:

1 + 2 + 1 = ?

2 + 2 = ?

Now add 2 and 2:

2 + 2 = 4

The sum is 4.

🖊️Add: 3 + 2 + 2 =

Hint: Start by adding a double.

First, add the doubles 2 and 2 to make 4:

3 + 2 + 2 = ?

3 + 4 = ?

Now add 3 and 4:

3 + 4 = 7

The sum is 7.
