🔢 Topic Summary
Subtraction is taking away a number from another. When we use our fingers, we can start with the bigger number and then count down by the smaller number. For example, if we have 5 - 2, we start with 5 fingers up and then put down 2 fingers. The number of fingers left is the answer!
Using fingers is a great way to visualize and understand subtraction, especially for grade 1 students. It makes learning math hands-on and interactive. Let's get started with some practice!
