In this activity, students are given a bingo board with various graphs sketched. They are also given 22 statements such as f ' (a) = 0 and
f "(a) > 0. This means they are looking for a graph on the bingo board that has a zero slope and is concave up. They try to match the 25 graphs with 22 statements which means that there are 3 blank ones too.
This is a good activity to practice the concept of 1st derivative (increasing, decreasing, and 0 slope) as well as 2nd derivative (concave up, concave down, and points of inflection) and how these concepts apply to the graphs.
