Update: Here is my blog post with a bit more on graphing calculators.
I am a big advocate for tech, especially graphing calculators for Math. I’m helping my husband, Rob, develop an Algebra 2 class for our Co-op. I know how to teach; Rob understands Math. He is using Glencoe Algebra 2, the 2005 edition. Why? Math does not change much; the 2005 edition is cheap used. Happily, this Algebra 2 edition has graphing exercises for TI 83/84. Guess what? Good Will online has used TI 83 calculators. My target price is around $15 for a TI 83 calculator. I try to pay $35-40 for a TI 84 calculator. Why should you learn how to graph with a graphing calculator? You may need to use one in college. Many public and private schools use graphing calculators in class. I introduce graphing in Chemistry, Physics, and Statistics for that reason. Kids should be exposed in high school. The textbook has instructions. Here are additional instructions. Feeling adventurous? TI 83/84 Plus has more exercises. Be sure the book has the CD. Use the TI Graphlink to download the apps from the CD directly to the calculator. Instructions are in the graphing book. You can do this!
