Students create different shapes by putting light on different objects. They change the distance from the object, the light source and angles to make the shadows different. They are to describe the relationship between the light, object...

Eighth graders use a meter stick that is placed on a horizontal surface and an object is moved along it so that the shadow length can be measured at different distances from the light source. They solve real-world problems involving...

In this geometry learning exercise, 10th graders use right triangle trigonometry to find the missing angle measure.  The two page learning exercise contains fourteen problems.  Answers are provided. 

Students use similar triangles to find missing heights.  In this using similar triangles to find missing heights lesson, students use proportions to find the heights of missing side lengths.  Students find the height of trees...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

In this algebra activity, students calculate the rate of change as it relates to height and length. This is a word problem with 3 specific math questions as to how Frank S. Key came up with the song "Me and My Shadow"

This applet helps students visualize the shapes of shadows cast by a cube with a light coming from different angles. This helps students visualize shapes from different angles and to identify, sketch and classify the cross-sections of...
