Actually, I just taught a "discovery" lesson on the Pythagorean Theorem this
past week to my 6th grade gifted and my 5th grade resource kids. All groups
(high and low) had a great time completing the task and discovering why the P.
Theorem actually works.
1. You need 3 triangles with the following angles: 1. right, 1 acute, 1
obtuse
2. It works best if you use 3 different colored sheets of paper, keeping each
"leg" the same color and the hypoteneuse the same color.
3. We had 12 x 18 " construction paper to glue our triangles on.
So, here's what we did. The resource kids we did together, the gifted kids, I
gave them the directions and let them run with it.
Easy "guided" version
Measure the hypoteneuse (c) of triangle 1, make a squard using that measurement;
for example, if the hypoteneuse measured 5 cm, students would make a 5 cm
squard. Glue it on your paper.
Measure leg a of your right triangle. Let's say it's 3, make a 3 cm square.
Glue on top of hypoteneuse square to cover the area.
Measure leg b of your right triangle. Let's say it's 4 cm, make a 4 cm square.
Glue it on top of hypoteneuse paper, you will have to cut it to make it fit.
Leg a squared plus leg b squared will cover the entire square of hypoteneuse
c.
Repeat the same procedure of the acute and obtuse angled triangles.
Results: acute: too much and will have extra
obtuse: not enough to cover the square of the hypoteneuse.
Time to complete activity: 30 minutes.
