We ended our unit on radicals in Algebra 2 with rational exponents and converting between radical form and rational exponent form. I created a visual summary of the process for my students to glue in their interactive notebooks as a sort of rational exponents graphic organizer.
I gave this page to my students, and I instructed them to choose a variable of their choice for the index of their radical and for the exponent of their radicand. One of my students thought it would make sense to use the variable e for the exponent and the variable i for the index. When you convert to rational exponent form, the exponent goes over the index in the fraction that forms the exponent. Exponent Over Index. EOI.
The standardized tests that Oklahoma high school students take at the end of the year are known as End-Of-Instruction (EOI) tests. So, this mnemonic device really only has special meaning to Oklahoma high school students. But, I was so proud of my student for creating something to help her remember something she deemed important and sharing it with the class. I was so impressed, I shared the idea with my other Algebra 2 period. They didn’t seem too thrilled or impressed, but I saw some students writing “EOI” on their quizzes. So, I think it helped.
I’m thinking that you could maybe find a way to relate it to Old MacDonald??? “Old MacDonald Had a Farm. E I E I O.” Okay, maybe that’s stretching it.
