Overview
theorem and know how to proof. We will use Kerpoof to
help student understand this theorem.
Students can understand the relationship between the
Objective
angles and edges of a right triangle.
[Cognitive objectives]
Standards
(1) Know and understand the Pythagorean Theorem and
use it to find the length of the missing side of a right
(Taiwan)
triangle and the lengths of other line segments. Use
direct measurements to test conjectures about
triangles.

(1) Explain the Pythagorean theorem and show one of the
proofs of this theorem.
(2) Students use Kerpoof to draw right triangles, then
draw squares on each edge .
Procedure
(3) The students will be asked to measure the areas of
each square.
(4) Analyze the patterns that the students have drew and
make a conclusion:
A2+B2=C2
C

After being taught about the Pythagorean theorem, the
students will be quizzed on what they have learned and

should have learned. They will know and understand the
Pythagorean Theorem A2+B2=C2.
