Reviews

[Simone Konner · Rating 4 out of 5]

An excellent way to add reading to the math classroom. Students will groan at first, but once they get into the story, they attend to learning trig and seem to have a deeper understanding of the material.

[Robert D]

A very creative and whimsical story-approach to learning trigonometry.
