Key Concepts
-When students understand the properties of a rectangle and how to calculate the area, they can apply this to learn the area of a parallelogram.
When you know the properties of rectangles, parallelograms you can figure out the area formulae of both shapes
I can calculate the area of a rectangle.
I can use what I know about the properties of parallelograms, while knowing how to calculate the area of a rectangle to find the area of parallelograms
(Virtually students can work on the Geoboard app to create their shapes)
Teacher notes: Students can be given two short and two long straws. Some of them will consider only polygons, whereas others may allow for other sorts of shapes as well.
Some students will investigate what they can do only with the given straw lengths. For example, given two 10 cm and two 12 cm straws, they could make a parallelogram of specific dimensions. However, other students might generalize to what happens with any two pairs of side lengths. Some students will assume that four straws must be used and others will consider the possibility of using only three of the straws or maybe even only two of them (to create angles). Every student in the class will be able to attack the problem at some level.
