Tuesday: complete Pythagorean Tree performance task

11/25/2014

 
Notes:
  • Groups chose the question they wanted to answer.  Every group either looked for the area of the tree or the area of the triangles (found in the negative space).
  • In both classes 3 groups found nearly exact answers, 2 groups were significantly far from the target and 2 were somewhere in the middle
  • Methods used: building scale models, measuring from the projected image, and finding that the largest leg created an area 64% of the hypotenuse area, and the smaller leg created a square 36% of the area.
  • Only one student used Pythagorean Theorem to solve the problem
  • Next year, I will teach the Pythagorean directly before this PT.  This year, after direct instruction, we will revisit this PT by creating a Pythagorean Tree Fractal for a bulletin board.
