Summary
Students were provided with vertices for different polygons and then asked to find corresponding vertices to complete given shapes. The activity allowed us to explore how we define polygons including squares, non-square rectangles, parallelograms and right triangles.
Ultimately the purpose of the activity was two-fold:
1. To get students to realize that orientation of a polygon does not change its properties. (That is, an upright square and a tilted square are both squares)
2. To eventually understand that if we know the area of a square, we will know the length of its sides, regardless of its orientation. This allows us to find the length of diagonal lines which is a skill that has eluded us thus far.
As a side note, students should have developed a method for finding vertical/horizontal distances using only ordered pairs without the use of a map or grid. Ask your child to demonstrate this skill to you.
