hi MathsIsFun

That's a useful little activity that could be a helpful part of a lesson on primes.  smile

Re: Prime Numbers Activity

Hi;

Should illustrate the fact that after you highlight 13 you are done.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Question: do you have to continue marking the whole chart, or can you stop at some point?

I think it's a good teaching point to allow students to think about this themselves.

I agree.

Re: Prime Numbers Activity

Better to start at the beginning isn't it..........  I think it should make a noise when you find a prime.
