Today PJ and I had two sessions. In the first session we reviewed yesterday's work on setting up inequalities. We discussed if a student thought of a number less than 17, what would the possible solutions be? PJ said, 15, 14, or even into the negatives. He was correct. I asked could the student be thinking of 17? He answered No since it said "Less than". Then we used a number line to graph the possible solution set. We used an open circle to indicate 17 could not be included and we shaded the line to the left, to indicate all numbers below 17 should be included in the answers.
In the 2nd session, we practiced checking to see if solutions given would solve the inequality given. This exercise was to help PJ visualize the answers.
