Product Description

This activity will lead middle school students through constructing triangles and rectangles that are related to each other to determine a method for finding the area of a triangle.

There are three parts of the investigation:

• Finding the area of triangles where there is one horizontal and one vertical side

• Finding the area of triangles where there is one horizontal or one vertical side

• Finding the area of triangles where the vertices at (0,0), (b,0), (c,d).

The investigation ends with the students summarizing what they have discovered.

The directions are given in two formats:

• All four parts on one page, or

• All four parts on four half sheets of paper.

A full set of suggested answers is included.

Comments from buyers:

  • I love using hands on lessons with my middle schoolers, and they love it as well.
  • Good
  • Awesome
  • Great Resource - thank you!
  • Great for a hands on activity
  • While this was challenging for my ELL fifth graders to work through alone, it was a perfect way to help me explain how to find the area of triangles using a tool they know--the geoboard! They wanted to know how to do this after our discussion of areas of rectangles, squares, so I used this whole class. Great job on this...I'm sure your middle school students love this.
