Students will be able to find summations and use these to find areas under curves.
In the beginning problems, students will be able to find summations with small upper bounds, then they will be able to use formulas to find sums with large upper bounds.
Eventually they will use this along with limits to find infinite sums, and hence find areas under curves.
This video introduces the vocabulary and notation of summations.
Bobby, Alec, and I do a few problems involving summations.
