Subtracting by counting back is a strategy where you start with the larger number and count backward to find the answer. This helps when subtracting small numbers, especially with facts up to 20.
Always begin with the bigger number and count backward the smaller number of steps.
You can use counting back when the numbers are small and the subtraction is easy to track on your fingers or in your head.
If the number being subtracted is very small (like 1, 2, or 3), counting back is quick and reliable.
A number line can help you see subtraction. Start at the bigger number and hop back the smaller number of steps.
Using a number line is helpful if you lose track when counting in your head. It shows the jumps clearly.
It helps to think of subtraction in word problems. Counting back works well in real-life situations.
Always connect subtraction to real-world examples. It makes the strategy easier to understand and remember.
