This card sort activity asks students to match a real-world situation with expressions that mathematically model those situations. Card sorts are great collaborative activities that offer something different from pen-and-paper work. Raise the stakes by offering a prize to the group that correctly matches the cards first!

By completing this worksheet, students will become comfortable with the concepts of Sine, Cosine, and Tangent. Students will become comfortable identifying the hypotenuse as well as the opposite and adjacent sides in relation to an angle in a right triangle.

This problem set assesses students' ability to use proportions to find missing side lengths in similar triangles.

This short exercise set assesses students' ability to apply the theorems for special right triangles (45-45-90 and 30-60-90) to find missing side lengths. Can be used as in-class practice, homework, or a quiz.
