Groovy+Math

Hey, students! Go to Mathtrain and find a cool video. Find the Embed portion, copy it, go to this page, hit the edit page button, hit the TV icon, hit the Other HTML link, paste the HTML code from the video, hit save, and add it to this page! media type="custom" key="3444434" This one is about adding and subtracting integers (whole numbers that are either negative or positive). media type="custom" key="3444468" This one is useless but downright fabulous! media type="custom" key="3444534" This is not the way I would have done the problem, nor is it the way I was taught as a kid. However, changing the fractions into improper fractions works at least as well in this example as rewriting the first fraction so that subtraction is possible. Interesting....
