Geometry Curriculum Unit 10: Area

Geometry Unit 10 covers area in high school geometry with guided notes, practice and activities. It includes everything you need to teach the area of triangles, quadrilaterals, regular polygons, composite figures and shaded regions, along with area relationships in similar figures.

The unit is ready to use and structured to cut your planning time. Students build a concept-driven understanding of area and get multiple opportunities to practice through notes, guided examples, independent practice and activities.

What’s included

• Unit prep materials: pacing guide, vocabulary lists, pre-assessment, warm-ups, exit tickets and lesson plan templates
• 7 complete lessons, listed under Topics covered
• Editable version to customize for your specific needs
• Assessments: quizzes, end-of-unit study guide and unit exam
• Answer keys for all practice pages, activities and assessments

The following activities are included:

• Area and Perimeter of Similar Figures Practice – Geometry Partner Activity
• Area of Composite Figures and Shaded Regions Maze – Geometry Activity
• Area of Quadrilaterals Geometry Activity for Rectangles, Trapezoids & Kites
• Circumference and Area of Circles Maze – Geometry Activity
• Perimeter – Self-Checking Geometry Activity for Polygons & Right Triangles
• Polygon Area Coloring Activity – Apothem, Radius, and Side Length Practice
• Triangle Area Matching Geometry Activity with Trig & Coordinate Problems

Topics covered

The 7 lessons:

• Perimeter
• Circumference and area of circles
• Area of triangles (including trig-based formulas)
• Area of quadrilaterals (parallelograms, trapezoids, kites, rectangles, squares)
• Area of regular polygons (using apothem, radius and perimeter)
• Perimeter and area of similar figures
• Area of composite figures and shaded regions

Good to know

• You must have PowerPoint to edit the editable version.
• The notes are detailed and scaffolded, which cuts your prep time.
• The activities require real thinking and go beyond plugging numbers into formulas.
• The assessments are written to measure understanding.
• Clear pacing keeps the unit manageable and predictable.
• The unit was written by an experienced geometry teacher who knows what works in the classroom.
