Pre-K-2, 3-5, 6-8, 9-12
Use this tool to create a spinner to examine experimental and theoretical outcomes.
3-5, 6-8
This applet allows you to examine various two-dimensional figures to determine which ones can be folded into a cube.
6-8
Use this tool to determine how the length of the base and the height of a
triangle, parallelogram, or trapezoid can be used to determine its area.
Pre-K-2, 3-5, 6-8
This tool allows you to create any geometric shape
imaginable. Squares, triangles, rhombi, trapezoids and hexagons can be created,
colored, enlarged, shrunk, rotated, reflected, sliced, and glued together.
9-12
Explore the amplitude, period, and phase shift by
examining the graphs of various trigonometric functions.
