 * **Number** || **Topic** || **Time** || **Comments** || **Approved by** ||
 * 1 || Fractions - Multiply || (2:26) || The whole video is 2:26, but the first 55 seconds solely focuses on multiplying fractions. || Denise ||
 * 2 || Fractions - Multiply (Mixed) || (5:08) || The video is a bit long. I don't overly like the method he uses to simplify the answer, but the strategy he uses to multiply the mixed fractions is very through. || Denise ||
 * 3 || Fractions - Divide (Mixed) || (4:52) || I would have liked if the video explained why the "flip and multiply" rule works for diving fractions, but this video has some great details. || Denise ||
 * 4 || Visual Division of Fractions || (11:05) || mmm pizza!, good visuals for breaking down fractions, a bit long but you can watch it fully and just use certain sections || Justin ||
 * 5 || Graphing - Coordinate Grid || (5:02) || Does a good job at visually showing all the components of a corrdinate grid. Colourful :) || Justin ||
 * 6 || Graphing - Reflections || (3:39) || tenmarks videos, a bit boring but well explained! on reflections of x and y axis || Justin ||
 * 7 || Graphing - Rotations || (5:38) || .Good starting example, but could become more complicated when having to explain rotating by angles that aren't 90 degrees. || K.V. ||
 * 8 || Graphing - Translations || (3:46) || Showed each translation of the polygon. Could have explained why translating by a negative number would make it go left or down (depending on coordinate). || K.V. ||
 * 9 || Integers - Multiply || (4:47) || Short, straight to the point and covers all 4 cases. Made sure to make all positive numbers green and all negative numbers red - complimentary colours are nice. || K.V. ||
 * 10 || Integers - Divide || (3:23) || This video is pretty clear on the two main rules of dividing integers, and does a good job of giving relevant examples. The numbers are written by hand on the screen and are a little messy, but still legible. || Peter ||
 * 11 || Interest || (3:51) || A very good introduction to simple interest. He explains the basic concept, then defines the important terms, and finally ties it in to a formula for calculating simple interest. || Peter ||
 * 12 || Order of Operations || (9:40) || This one is a little long, but it explains the concepts well. He starts out by explaining why we need a set of mutually agreed-upon order of operations, then explains the way BEDMAS works (they call it PEMDAS in this video) || Peter ||
 * 13 || Percents - Calculating || (2:01) || Great connection to why it should matter to students. || Andrew ||
 * 14 || Prime Factors || (2:01) || Quick explanation of factor tree method. A little distracting because she can write backwards on glass. || Andrew ||
 * 15 || Ratio Problems || (3:54) || This video is rather simple compared to Kahn, but it goes at a pace where the student can follow along, and uses actual problems to go through. || Andrew ||
 * 16 || Sales - Commissions || (2:00) || Student made video with real world examples || Lukas ||
 * 17 || Sales - Discounts || (3:08) || Discount formula, example, and resulting 'sale price' explained || Lukas ||
 * 18 || Sales - Tax || (3:06) || Problem with step by step instructions || Lukas ||
