6.1.5 Digital Applets: A Parallelogram and its Rectangles, The Right Height

This is an assignable version of the digital applet that goes with Grade 6, Unit 1, Lesson 5: Bases and Heights of Parallelograms. 


In the first applet, students compare and contrast two ways of decomposing and rearranging a parallelogram on a grid such that its area can be found. It serves a few purposes: to reinforce the work done in the previous lesson; to allow students to practice communicating their observations; and to shed light on the features of a parallelogram that are useful for finding area—a base and a corresponding height.

The second applet is a dynamic parallelogram with a height displayed. It allows students to see placements of height in a variety of parallelograms and when any side is chosen as a base.
