SlopeoMeter

The Slopeometer™ is a simple device that gives students a concrete visual as they learn to measure and demonstrate positive and negative slope. Place the Slopeometer on any magnetic surface and the arrow will smoothly move back and forth to show the precise measurement of slope from 0 to infinity, positive and negative. A great teaching tool for simple slope-intercept (y = mx + b) equations to the complex sketching of derivatives in a calculus class. Measures 14" x 7-3/8" and is made of durable, transparent plastic to easily view the coordinate graph behind it.
