Chautauqua:
The Medicine Wheel
Math: Investigation 3.2- Students find angle sums and then form conjectures about the relationship between the
number of sides and the angle sum of any polygon.
Investigation 3.3-Students look at regular polygons and figure out which regular polygons will tile a plane by themselves or in combinations by usinginformation about the corner angle.
Investigation 4.1-Students use Polystrips to build triangles given three side lengths. They observe that the sum of two side lengths of a triangle must be greater than the third side length and for three lengths that work there is exactly one triangle that can be built.
Investigation 4.2- Students use Polystrips to build quadrilaterals given four side lengths. They find that to make a quadrilateral, the sum of three side lengths must be greater than the fourth side length. If a
quadrilateral can be built, they also learn that different combinations of the side lengths will produce different shaped quadrilaterals.
