Adding 1

key notes :

Understanding Addition:

  • Explain that addition is the process of putting numbers together to find out how many there are in total.

Introducing the Concept of Adding 1:

  • Start with the idea that adding 1 means counting up by one number. For example, if you have 2 apples and add 1 more, you now have 3 apples.

Number Line Use:

  • Introduce a number line and demonstrate how to add 1 by moving one step to the right.

Counting Objects:

  • Use real objects like blocks, counters, or fingers to physically add one more and see the result.

Simple Addition Facts:

  • Practice with simple equations such as 1+1=2, 2+1=3, 3+1=4, and so on.

Learn with an example

🗼 Add. 0+1=

When you add 0 to a number, the number stays the same.

0+1=1

🗼 Add. 6+1=

  • You can count on to find 6+1.
  • Start at 6 and count on 1 time.
  • You end at 7.
  • 6+1=7

🗼 Add. 1+4=

  • You can count on to find 1+4.
  • It is easier to start with the larger number. So, start at 4. Count on 1 time.
  • You end at 5.
  • 1+4=5
