**Title:** I Can Determine The Height Of A Rocket!

**Description:**
The lesson is intended to give students a fun real-world experience in applying their math skills. They will use trigonometric ratios to calculate heights of tall structures. They will also use the Internet to convert their calculations from standard to metric units and visa versa.

**Standard(s): **

[TC2] CA2 (9-12) 11: Critique digital content for validity, accuracy, bias, currency, and relevance.

[MA2013] AL1 (9-12) 4: Use units as a way to understand problems and to guide the solution of multistep problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays. [N-Q1]

[MA2013] AL1 (9-12) 5: Define appropriate quantities for the purpose of descriptive modeling. [N-Q2]

[MA2013] AL1 (9-12) 6: Choose a level of accuracy appropriate to limitations on measurement when reporting quantities. [N-Q3]

[MA2013] ALC (9-12) 8: Determine missing information in an application-based situation using properties of right triangles, including trigonometric ratios and the Pythagorean Theorem. (Alabama)

[MA2013] ALT (9-12) 39: Define the six trigonometric functions using ratios of the sides of a right triangle, coordinates on the unit circle, and the reciprocal of other functions. (Alabama)

[MA2013] GEO (9-12) 15: Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain using similarity transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides. [G-SRT2]

[MA2013] GEO (9-12) 18: Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures. [G-SRT5]

[MA2013] GEO (9-12) 19: Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle leading to definitions of trigonometric ratios for acute angles. [G-SRT6]

[MA2013] GEO (9-12) 21: Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.* [G-SRT8]

[MA2013] GEO (9-12) 39: Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder).* [G-MG1]
