We have ten fingers and ten toes because our bodies are built to count using these body parts as tools, just like you might use blocks or apples when learning how to count.
How Our Bodies Count
Imagine your hands are like little counting machines. Each finger is a number, so with both hands, you can count up to 10. That’s why people often use their fingers when they’re trying to add or subtract, it's a natural way to help them think.
Why Ten?
Think of the numbers on a clock face: there are ten digits we usually use every day, from 0 to 9. Having ten fingers and ten toes gives us a handy tool for counting, just like having two hands makes it easy to hold things or clap.
It’s like you have your own little number system right in your body, ready to help you learn and play!
