Simple way to learn Maths subtraction

Simple way to learn Maths subtraction.

I bought these cute “stick marker” from the 12 dollars shop in Aeon, and stuck magnets at the back of each animals. That’s it.

I randomly selected 10 animals out. We worked our way from subtracting 1 to all 10.
So for example, “10 take away 5” we would “bend” 5 animal stickers and so J can count the remaining animals to work out the answer.
