Today, I'm posting Unit 4's INB pages for Algebra 2. Yes, I realize I'm posting these out of order. I'm becoming less and less of a perfectionist about these things. And, I'm not sure if this is good or bad.
This is a unit I want to do some serious revamping of this summer. These pages have remained basically unchanged since I started teaching sequences and series. I think my teaching has improved; now I need to come up with a way to improve my notes.
A couple of students suggested that I spend more time having them find values recursively before I ever give them formulas. I think this is definitely worth considering! I see the need for the formula. Now, I need to get my kiddos to see the need for the formula.
Ideas for revamping this unit:
Sequence vs Series Card Sort - Some students seem to confuse the definition of series with the definition of arithmetic. Fix this!
Arithmetic vs Geometric Card Sort - Students must determine whether to solve for r or d!
Solve Two Ways - Make a notebook page where students have to solve for a certain term or sum recursively AND using the formula.
Word Problem Practice - Put more word problems and their worked solutions in our notebooks! Students seem to struggle with determining arithmetic vs. geometric from a story problem.
Dice - Have students generate their own sequences somehow. Roll a die. This is a sub one. Roll the die again. This is a sub two. If this sequence is arithmetic, continue it. If this sequence is geometric, continue it.
