Abercrombie’s Angle Adventure (Angles Untangled!) focuses on supplementary and complementary angles and interior and exterior angles of polygons. Students are guided through five days of common core aligned notes, worksheets, and activities as they join the skateboarder, Abercrombie, in his quest to see what he can discover about angles. The unit assessment is administered after the final lesson.

This unit contains:

Abercrombie’s Angle Adventure – Introduction. This introduces Abercrombie – who he is and the adventures upon which he will embark.

Abercrombie’s Angle Exploration. These illustrated notes refresh the students’ memories on angle terminology, most commonly used angles, and supplementary and complementary angles.

Abercrombie’s Supplementary and Complementary Angle Problems. In this worksheet, students use supplementary and complementary angles to find various angle measures using simple equations, and think critically about how angle measurements can be combined.

Abercrombie’s Polygon Interior Angle Voyage of Discovery. This lesson allows students to analyze interior angle sums for a variety of polygons, then guides them through tabulation of interior angle sum data, a search for patterns, and the eventual derivation of a formula (equation) for the sum of the interior angles of a polygon with n sides.

Abercrombie Uses Interior Angle Sums and Supplementary Angles. In this lesson, students use their new discoveries about interior angle measures and supplementary angles to determine the measures of a number of different angles of polygons using simple equations.

Extension – Interior Angle Measures of Regular Polygons. This is a critical thinking enrichment lesson that may be used for more advanced students. Students apply their knowledge of interior angle sums to polygons in which all angles are congruent. They determine the measures of each interior angle of various regular polygons, and then make conjectures about what happens to these angle measurements as the number of sides gets very large.

Abercrombie’s Skateboarding Adventure. This is the final chapter to Abercrombie’s angle exploration, during which he visits three different parks, skateboards around them, and makes observations about the exterior angles and the exterior angle sum of each of the parks. All that Abercrombie has learned to this point is put to use in this skateboarding adventure.

Abercrombie Skateboarding Adventure Follow-Up Problems - A worksheet where students use exterior angle sums and other concepts from previous lessons to solve a variety of angle problems.

Supplementary/Interior/Exterior Angle Unit Assessment – The end-of-the-unit test. This may also be used as a pre-test!

Detailed teacher instructions and keys are provided for all worksheets and activities. Your students will love Abercrombie and his high-flying angle adventure!
