I have found that getting students to understand the concepts of slope and y-intercepts is difficult, but can be made easier for the teacher by having the students do more observation and problem-solving than by simply listening to the teacher lecture.
I wrote this worksheet so that my students could walk away with a basic idea of slope and y-intercept. One weakness of this worksheet is that each square is automatically one unit, which can throw students off if the grid counts by 2's or 5's or some other multiple.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
