Ending Our Unit Of Measurement On Radicals

My Algebra two students lead keep moved into logarithm territory, then I gauge it's best fourth dimension I post the residual of our interactive notebook pages regarding radicals.  We form of got off to a bad showtime alongside logarithms.  I seriously blame it on the wintertime weather.  But, I think most of my students lead keep lastly caught on too realized that logarithms exclusively await scary.  But, to a greater extent than most them inwards a hereafter post.

Radicals.  Earlier, I posted pictures of the pages nosotros made that dealt alongside prime number factorization, parts of a radical, simplifying radicals, adding too subtracting radicals, too multiplying radicals.  The latter one-half of our unit of measurement covered dividing radicals, rationalizing the denominator, too converting betwixt radical shape too rational exponent form.

I shared alongside my students the argue why standardized tests require them to rationalize the denominator.  I gave them a long segmentation occupation to create yesteryear hand.  It was non pretty.  They cannot divide.  At all.  If I had to a greater extent than time, I would lead keep had them write a persuasive newspaper over whether students should live required to rationalize the denominator inwards this 24-hour interval too historic menstruation of technology.  I loathe the fact that I lead keep then much to comprehend inwards Algebra 2.  The bulk of my students' Algebra 1 background is extremely lacking, however.  So, I've had to create around necessary reteaching.  Plus, I silent lead keep to brand certain I instruct all of the Algebra two standards.  It's a lot to do, merely I'm doing the best that I can.

I gave this page to my students, too I instructed them to select a variable of their selection for the index of their radical too for the exponent of their radicand.  One of my students thought it would brand feel to role the variable e for the exponent too the variable i for the index.  When you lot convert to rational exponent form, the exponent goes over the index inwards the fraction that forms the exponent.  Exponent Over Index.  EOI.  The standardized tests that Oklahoma high schoolhouse students accept at the halt of the twelvemonth are known every bit End-Of-Instruction (EOI) tests.  So, this mnemonic device actually exclusively has exceptional pregnant to Oklahoma high schoolhouse students.  But, I was then proud of my pupil for creating something to assist her recall something she deemed of import too sharing it alongside the class.  I was then impressed, I shared the thought alongside my other Algebra two period.  They didn't appear besides thrilled or impressed, merely I saw around students writing "EOI" on their quizzes.  So, I think it helped.  

I'm thinking that you lot could possibly abide by a means to relate it to Old MacDonald???  "Old MacDonald Had a Farm.  E I due east I O."  Okay, possibly that's stretching it.
