Ch 8: Quadrilaterals: Homeschool Curriculum

About This Chapter

The Quadrilaterals unit of this High School Geometry Homeschool course is designed to help homeschooled students learn about parallelograms and other 4-sided figures. Parents can use the short videos to introduce topics, break up lessons and keep students engaged.

Who's it for?

This unit of our High School Geometry Homeschool course will benefit any student who is trying to learn about parallelograms and other 4-sided figures. There is no faster or easier way to learn about quadrilaterals. Among those who would benefit are:

  • Students who require an efficient, self-paced course of study to learn about the properties of parallelograms, rhombuses, kites, trapezoids and more traditional quadrilaterals.
  • Homeschool parents looking to spend less time preparing lessons and more time teaching.
  • Homeschool parents who need a math curriculum that appeals to multiple learning types (visual or auditory).
  • Gifted students and students with learning differences.

How it works:

  • Students watch a short, fun video lesson that covers a specific unit topic.
  • Students and parents can refer to the video transcripts to reinforce learning.
  • Short quizzes and the Quadrilaterals unit exam confirm understanding or identify any topics that require review.

Quadrilaterals Unit Objectives:

  • Illustrate and explain the construction of rectangles.
  • Learn to apply the area formula for rectangles.
  • Define squares and discuss their properties.
  • Discuss why quadrilaterals qualify as parallelograms or rhombuses.
  • Compare the properties of kites and rhombuses.
  • Learn to measure the area of trapezoids.
  • Use Heron's formula, and illustrate with examples.
