Any ideas out there for prime and composite numbers, square numbers as in with an exponent, factors, and prime factorization? Thanks

As a second grade teacher, the only thing I can possibly offer is an idea for a gesture for SQUARE: Have you seen the older Nationwide Insurance commercials where the policy holders make a frame with their hands around their face? It's kinda like a square. OK, that's it. Thank heavens I don't have to teach the rest of that! LOL:cheer:
