The Math & Astronomy Toolset

Coordinate System Board Game

An engaging board game with a grid centered at (0,0), and -10 to +10 in X and Y directions. Players use two 20-face dice (white for Y, black for X) to determine coordinates. Students plot points and calculate the distance from the origin using the Pythagorean theorem, enhancing their understanding of coordinate systems and mapping.

Trig Ruler: Trigonometry in Motion

A unique ruler with Hypotenuse, Base, and Perpendicular scales, each 1 unit (100 smaller units) long. The Base and Perpendicular scales pivot on the Hypotenuse. A 0-360° circular disc is also attached. Students form a right-angle triangle by adjusting the Hypotenuse to an angle (0-90°). Cosine and Sine values are read directly from the Base and Perpendicular scales at their intersection.

Thread Ruler & Multi-Function Drafting Instrument

A single versatile instrument for drawing circles, ellipses, and parallel lines, doubling as a protractor, ruler, and drawing compass. It features a slide ruler holding a marking device and a stem with a thread. The thread attaches to the main ruler body for drawing ellipses. Usable on paper, drafting tables, chalkboards, and dry erase boards.

Sky Tracker Planisphere: Global Star Locator

Our unique Planisphere combines a circular overlay star chart with a circular stereographic Earth map, connected at the center for free rotation. This allows users to view the night sky from any part of Earth by aligning the Right Ascension on the star chart with any Earth longitude on the stereographic map.

Elliptical Bubble Leveler: Precision Angle

This innovative bubble leveler features a unique elliptical tube, unlike traditional designs. Its precisely curved tube ensures the bubble moves proportionally to the angle of inclination, directly indicating the exact angle on a clearly marked elliptical scale. This provides unparalleled accuracy and responsiveness for measuring angles on any surface.

3D-Compass: Pointing to Celestial Objects

A tool to point to objects in a spherical coordinate system, like stars. Made of two semi-circle protractors (-90° to +90°), one for Declination/Zenith angle and the other for Right Ascension/Horizon, folded perpendicularly. The RA half has a magnetic compass, and the Dec half has a sliding arrow. Aligning the compass needle with RA and rotating horizontally places the Dec half in the star's plane; sliding the pointer to the star's declination then points to its direction.
