Bouncing Barney
– an exploration of paths of lines inside a triangle from a point on one
side of the triangle to another side of the triangle, that is parallel to
the third side of the triangle.
Inner
Secants – an exploration of the relationship of the measure of an angle
formed by two secants that intersect outside the circle and two arcs
created by the secants.
Orthocenters –
an exploration of the orthocenter of a triangle. This includes an exploration into how the orthocenter
moves in and around the triangle.
Quadrilaterals – an
exploration of the relationship between an original quadrilateral and a
smaller quadrilateral created by connecting the midpoints of the original
quadrilateral.
Pythagoren
Theorem – an exploration of the Pythagorean Theorem using GSP to
manipulate triangles.
Lesson Plans
Arc length and area of a sector – this
lesson plan uses GSP to help students explore the relationships between the
arc length and the circumference, the area of a sector and the area of a
circle, and the measure of a central and the area of the circle.
Pythagorean Thoerem – this lesson
uses GSP to help students explore how the measure of an angle affects the
relationship between the sum of the squares of the adjacent sides and the square
of the opposite side.
