Patent attributes
Devices and methods for hands-on learning of mathematical parabolic concepts are provided. For example, a device for teaching mathematics includes a base having a plurality of channels for accepting vertical rods of varying lengths; a lever movably attached to the base at a pivot, the lever passing through the plurality of channels; and a plurality of vertical rods, each of the plurality of vertical rods located at least partially in one of the plurality of channels and resting on the lever; wherein the plurality of vertical rods are sized and arranged so that the tops of the vertical rods illustrate a parabolic function; and wherein moving the lever about the pivot moves the plurality of rods within the plurality of channels and illustrates changes to the parabolic function represented by the vertical rods.
