25, 78, 100

I know these are the composite numbers, because they can be put into equal  groups.
I also have them colored in as composite numbers on my hundreds chart.


These are the  prime numbers:
79

I know this is a prime number because it can only be divisible by one or itself.
I also have it colored in as a prime number on my hundreds chart.
