This Instructional Activity is a part of the Lesson 5, Unit 1, Grade 6. Previously, students saw numerical examples of a base and a height of a parallelogram. This activity further develops the idea of base and height through examples and non-examples and error analysis. Some important ideas to be uncovered here: In a parallelogram, the term "base" refers to the length of one side and "height" to the length of a perpendicular segment between that side and the opposite side.
