Hi, my name is Stefan. Today, I'm going to be speaking on interactive math games for grades 9 through 12. A good way to get the students to interact in game is break them up into groups. You'll have around 4 people in a group and what we'll do is I'll start off with a number and I'll have the first person, I'll say "okay, take the number and multiply it times 3". So the person one's job is to multiply it times 3. And then I'll have the second person multiply the same number by 20 , and the third person I'll have them take the square root of the number. And then the fourth person I'll have them divide the number by 4. And breaking them up into groups I'll have the first group to give me the correct answer of the initial number I gave, they'll be the winner. This is good because it'll have the students interact with each other. They'll pass the number onto this person, then they'll pass the number onto this person and so on. So they all have to work in order to get the correct answer.
