Subtraction by Crossing out
This is the basics of subtraction like they do in picture subtraction.
Reinforce that when we subtract one from any number the answer is the number that comes before.
Explain the concept of zero to reinforce the concept. Reinforce that when we subtract zero from any number the answer is the number itself. Make sure that you teach your child that zero has no value. So adding zero and subtracting zero to any number the answer is the number itself. Thus, we have 1 – 0 = 1.

To make the kids understand this concept when you subtract a number from the same number, the answer is zero teach them by objects. For example, Hema has 6 balloons and all 6 balloons burst out. So how many balloons are left?

Subtraction Using the Number Line
To add using the number line, you jump forward. To subtract using the number, you jump backward. give repeated practice to the children to draw a number line for different subtraction problems.
