I’m a high school math teacher finishing off my geometry class (9th and 10th graders) with a unit on probability. I’m requiring students to use fractions in their calculations, and that is of course a struggle for many students.

My question is whether you think that most of these students never understood basic fraction arithmetic (+, -, x, /, lowest terms) or they understood at one point, but have totally forgotten?

I am painfully aware of how difficult it is for many of my students to remember much of anything. But it’s hard to tackle math if little to nothing ever goes into your long-term memory. Thoughts?
