The best thing to do would be to take a data approach to lines so that students understand what the real meaning is of slope (a rate of change) and of y-intercept. Units 1 & 2 of the Investigating Change by Mary Barnes gives a wonderful approach to what I am talking about - present algebra in a context. Dale Seymoour Pub. also has a book called Exploring Linear Relations by Gail Burrill and Patrick Hopfensperger that does a great job of explanation. Pick up ALgebra I experiments. The relationships that exist between any two phenomena is explained using algebra! I do the bouncing ball experiment with my algebra kids and they get involved very much. Students finally ask if they are going to find algebra in everything? The answer is "YES!" If you need more ideas, please write back! -Claudia, for the Teacher2Teacher service
