Subtraction on a number line is like taking a little walk backward! You start at the bigger number and then hop back the number of spaces you're subtracting. The number you land on is your answer! Number lines make subtraction easier to understand because you can see exactly how many spaces you're taking away.
Imagine you're a little frog 🐸 jumping along the number line. You start at your first number, and then you jump backwards based on what you're subtracting. The spot you land on is your answer!
