This SmartBoard lesson is intended to be a whole group/active engagement discussion after students have worked with quadrilaterals, partitioning shapes, and finding area. Students should be able to draw the shapes and talk about the discussion questions. Be ready to talk about fractions, area, and problem solving. After the lesson, students should try problems on their own. I used this assessment http://www.teacherspayteachers.com/Product/Common-Core-Math-Assessment-Grade-3-G2-Geometry-Partitioning-Shapes-495359 to follow the lesson.
