Prime Numbers Activity
Make your own prime number chart!
Click on any number to have it:
- marked gold (a possible prime number),
- and all its multiples marked blue (definitely composite numbers).
Keep marking numbers, until finally you will have a list of only prime numbers and composite numbers
Oh, and 1 is neither prime nor composite, so you can't mark it.
Question: if you could choose "1", what would happen?
Question: what if you don't mark the first part of the chart?
Question: do you have to mark the whole chart, or can you stop somewhere?
