I opened up my teacher edition last night to review the lesson and make some notes. I got to the rules of the absolute value inequalities and froze for a second. The definition was terribly technical. It took me two readings to make sure that I got it and my heart sank a little. I started trying to figure out how I was going to get the kiddos to understand that definition. I started looking through other resources that I had and found an explanation using two cases. After reading that, I created the the following chart:
|I got my examples from the McGraw-Hill Algebra 1 (2012 edition) textbook.|
I left the case 1 and case 2 parts blank and worked them in class along with drawing the graph of the solution. I like the idea of what I did, but I would like to redo it a bit. I would take out the "and" and "or" part by the inequality symbols. I don't think the kiddos got it right away. Next time, I will have them write it by the solutions graph. I am also not happy with the special cases part of the notes. Oh well! Summer is almost here and I am sure I'll find inspiration during it.
