Interactive video lesson plan for: How to write out the full series from its sum! (KristaKingMath)

Activity overview:

Sometimes you'll be given a sum in summation notation, and asked to expand the sum into a sum of individual terms.

What this really means is that you're going to look at the index, which is where the sum begins and ends, and then plug all of those values into the function, adding each value to the next, to create an expanded sum. Really all you're doing here is listing out the terms of the sum, instead of having them consolidated into one sum.

The expanded sum will represent exactly the same thing as the summation notation that you started with.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
