# Pythagoras Theorem

There’s some resources below, but first… a nice desmos activity to help introduce the concept with a fun task first before introducing Pythagoras to students.

HANDS ON/PRACTICAL:

See this link to using an origami activity to teach Pythagoras! (scroll to bottom of article)

DEMONSTRATION:

Nice visual water demonstration seeing how pythagoras works: http://blogs.rosebank.nsw.edu.au/slotter/2014/04/16/pythagoras-theorem-water-demo/

Desmos titles this one “Pythagorean Theorem Proofs without words!”

ONE OF DAN MEYER’S QUESTION SCENARIOS:

Need to use Pythagoras and some thinking to work it out!

WORKSHEET:

PythagorasPracticeSheet

Used for year 8, for students to practice being able to find both hypotenuse and short sides – to solve a riddle!

Another golf desmos activity – once they have the hang of Pythagoras or to check understanding maybe?

Can use the Taco Cart activity on Desmos as well for an application once they understand it.

NB: Robert K has this scarecrow activity as an intro… but not sure the context will capture interest?

How about this video – from about the mid-point – to inspire/challenge some thinking!! Talking about the pursuit of the perfect cuboid. An interesting video anyway discussing what mathematicians generally do (problem solving!)

And for an extension – check out the Q in the image below:
