What does base 10 mean?

Base 10 means we use 10 digits to count everything, like counting apples or steps.

Imagine you have a bag of 10 different colored marbles, and every time you run out of one color, you switch to the next. That’s kind of how base 10 works! We start with 0 through 9, and once we reach 9, the next number is 10, like adding a new marble bag.

Think about your fingers. You have 10 fingers, right? That’s why humans often use base 10. When you count on your fingers, after 9, you use both hands to make 10.

Now imagine you're counting cookies. If you have 12 cookies, that means:

• You’ve used 1 full bag of marbles (or 10 cookies).
• And you have 2 extra cookies left, like having 2 more marbles in your hand.

So, base 10 is just a fun way to count with our favorite number of digits, 10! Base 10 means we use 10 digits to count everything, like counting apples or steps.
