Math Illumination ActivitiesBy Stefan Robert
Math illumination activities can involve a large number of different topics on numbers. Find out about math illumination activities with help from an expert in computers, with two degrees in both Computer Science and Applied Mathematics, in this free video clip.
Hi, my name is Stefan. Today, I'm going to be speaking on math illumination activities. One good activity I like to do for kids is, I'll have them pick any number, each student pick any number from one to nine. And then, I have them take that number, we'll call it X, multiplied it by nine. Then I'll say, the product of this number when you're given the two digits, add them together. And then, I'll get a final number, I'll call this Y. And then, I'll tell them if you're number does not equal nine, then you don't have any homework. And then, I'll say, if your number does equal nine, then you have homework. Well, the cool thing about this is, it's always going to equal nine. If you look at the nine times table, nine times one, nine times two, nine times three. You know, you get nine, 18, 27 and the summation of these are always going to equal nine. So, their ending numbers are always going to equal nine. So, they're always going to have homework. And this is a cool math illumination trick that I like to do in class.
