Before Friday's assessment I used the Hot Seat to review what would be on the assessment. I like how students pointed out that the unit rate couldn't be 8/3 because where x=1 the y axis was between 0 and 1.
After each student's turn on the hot seat, I ask volunteers to explain the answers before I advance to the next slide with the answers. I then see who got 2 points on the Hot seat and how many groups all correctly answered it. I encouraged students who weren't sure to ask their group and those that knew to check on their teammates.
