I covered solving absolute value equations with my freshman today. It is a concept that students typically catch on quickly to. The only new part is setting the equation inside the absolute value bars to the same and opposite to the number that the equation is equal to. Once again, for these topics I like to end the class with an interactive activity rather then drill and kill problems. I found the game modeled after "Who Wants to be a Millionaire." I divided my class into 2 groups and then showed the site on my projector and we played! To make things easier on me, I assigned one person in each group to be the official answer. I just listened to that person. The game is great and my students enjoyed it. The one snag...it was easy so once a team got picked they got all the questions right and never switched to the other team. I guess it is a good problem to have--the team that won the coin toss got all the problems right!
1) Will have students play against each other 1 to 1 in the computer lab
2) Will have all students write and work out each problem
Enjoy!I have attached a copy of the notes that I distributed to my students.
