Geometric series

Ahhhhh! It's that time of year when you hear RUMORS of students actually being enrolled in your classes, but you have scattered evidence. If it's not sickness, it's field trips or EOC exams or fill-in-the-blank reasons. Or if they ARE in class, some of them are NOT in class. If you know what I mean. Welcome to my Precalculus preAP experience. Because of this, I was trying to give this recently-absent child a run down of all things Sequences and Series. I sketched the following roughly on…

One of my last Algebra 2 units before state testing was arithmetic and geometric sequences and series. Our students are given the formulas for the nth term and the sum of the first n terms, but they are given no explanation for what each variable represents. So, I like to spend an entire class period discussing what each variable represents. Then, we look at word problems and label all of the information with the correct variable. The kids hate it, but it really helps them in the long run…

This is a full guide to finding the general term of sequences. There are examples provided to show you the step-by-step procedure for finding the general term of a sequence.

Learn the general form of the arithmetic series formula and the difference between an arithmetic sequence and an arithmetic series. Discover the partial sum notation and how to use it to calculate the sum of n terms.

Since I'm not that good at (as I like to call it) 'die-hard-mathematics', I've always liked concepts like the golden ratio or the dragon curve, which are easy to understand and explain but are

Exploring shapes, colors and expressions through illustration series of geometric style, creating lovely, intricate flat images based on colorful combinations and minimal shapes.

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 go

I created these arithmetic and geometric sequences and series foldables to help my Algebra 2 students to help them keep track of what each variable in the
