Ratio Rig Facilitation Guide
A comprehensive 2-page facilitation guide for teachers, including learning objectives, a detailed instructional routine (Engage, Explore, Explain, Apply), common misconceptions, and a progress monitoring rubric for the Ratio Rig lesson.
Ratio Rig Slides
A 5-slide visual presentation using a blueprint theme to introduce triangle similarity, side identification (Opposite, Adjacent, Hypotenuse), and the formal definitions of sine, cosine, and tangent with the SOH CAH TOA mnemonic.
Side Sleuths Worksheet
A 2-part scaffolded worksheet designed to guide students through calculating side ratios in similar right triangles, identifying sides relative to a reference angle, and applying SOH CAH TOA to find trig ratios.
Trig Talk Vocab Map
A visual vocabulary map for students defining the three primary trigonometric ratios (sine, cosine, tangent) and illustrating how to label the sides of a right triangle relative to a reference angle.
Trig Check Exit Ticket
A quick 3-question progress monitoring tool for the end of the lesson, covering side labeling, ratio setup, and a conceptual check on ratio consistency.
