Title: Learning Target Exit Slip: Perimeter and Area on the Coordinate Plane
Description:

In this activity, students will complete an exit slip using Google Forms. Students will begin the activity by rating their understanding of computing perimeters of polygons and the area of triangles and rectangles in the coordinate plane. Finally, students will respond to a short answer question in order to demonstrate mastery of the content standard.

This activity was created as a result of the ALEX Resource Development Summit.

Subject: Mathematics (9 - 12)
Title: Word Expert: Perimeter and Area on the Coordinate Plane
Description:

In this activity, students will work in groups to create posters using Google Slides. Each poster will demonstrate an understanding of geometry words/skills that are prerequisites for computing the perimeters of polygons and the area of triangles in the coordinate plane. Students will complete this activity by providing constructive feedback to their peers via a virtual gallery walk.

This activity results from the ALEX Resource Development Summit.

Subject: Mathematics (9 - 12)
Title: Perimeter and Area on the Coordinate Plane
Description:

In this lesson, students will use the distance formula and dynamic geometry software to compute the perimeter and area of polygons. Students will use the distance formula to calculate the length of each side of the given polygon.  Students will then compute the perimeter and area of each polygon.  All computations will be verified using a Geogebra applet.

This activity results from the ALEX Resource Development Summit.
