One of my high school math students’ most used math reference sheets is this free printable factors chart for the numbers from 1 to 100. I give my algebra and pre-calculus students a copy of this 1-100 factors chart at the beginning of the school year, and we end up referencing them a lot. This …

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 …

I took this idea and ran …

I created this prime factorization graphic organizer for my Algebra 1 students to summarize two different methods for finding prime factorization: the factor tree method and the birthday cake method. I teach my Algebra 1 students to simplify radicals through prime factorization because it works no matter what the index of the radical is. This …

Before I teach my algebra students to rationalize the denominator, I try to answer the looming question: why do we rationalize the denominator? I realize that rationalizing the denominator has gone out of fashion as a result of the Common Core State Standards, but the topic is still required by the Oklahoma math standards. I …
