After showing TIMMS clip from yesterday again. Think for two minutes on your own about how to start the lesson to address the students’ misconceptions and make sure they are ready to move on and how to activate the knowledge kids should have had about exponents.

Given a trapezoid OABC where OA = 4 cm AB = 2 cm OC = 6 cm AO perpendicular to OC M is a point moving on AO Triangle MBC and rectangle MNPO are such that N is on segment BC and P is on segment OC. Find the area of the triangle MBC and the area of the rectangle MNPO. What is the maximum area for the triangle MBC and the rectangle MNPO? When, if ever, will the area of the triangle be larger than the area of the rectangle?
