I created this free printable prime numbers chart that features all of the prime numbers under 100 for my Pre-Calculus students to reference while simplifying radicals recently. I think it would be useful for a much wider range of math students, though. My students were looking for a quick way to tell if a number was prime since they knew that prime radicands would never simplify.

I actually ended up combining this prime numbers under 100 chart with several other charts and creating a reference chart booklet for my students, but I will have to share that a different day!
