Today Carson and I continued working with the Pythagorean Theorem. We worked with Coffee stirrers. Carson cut them in lengths of 3cm, 4cm, 5cm, 6cm, 7cm, 12cm, and 13cm. We practiced putting them together to create a right triangle. What we noticed is that some lengths were too short or too long. But then we found that 3,4,5 worked together. I had Carson check that 3^2+4^2=5^2 when he checked it worked. So we proved that those side lengths would create a right triangle. Next we worked with 5, 12, 13 and found this also created a right triangle when we checked the pythagorean theorem. Next we discussed what happens when the side length isn't a perfect whole number. For example if we got sqrt 72, we discussed how we would used the factor tree to break it down into a product of primes and then reduce.
