Lesson Planet
This Module 7: Connecting Algebra and Geometry unit plan also includes:
The coordinate plane links key geometry and algebra concepts in this approachable but rigorous unit. The class starts by developing the distance formula from the Pythagorean Theorem, then moves to applications of slope. Activities justify the properties of geometric shapes in algebraic fashion, and investigate the translation of functions in geometric ways. A rare lesson that will appeal to both young geometers and algebra enthusiasts in your class.

Instructional Ideas
- Use a map as a coordinate grid for more practice finding the distance between points (with the added skill of scale factor)
- Good lesson for the end of a geometry course, to refresh needed algebra 2 skills
- Useful for remediation of algebra skills when necessary
Classroom Considerations
- Teaching notes available separately, under Included Materials
- English language learners might need additional supports, based on the vocabulary of the lesson (perpendicular, parallel, shape names, etc. all used without introduction)
Pros
- Unique approach strengthens both algebra skill and geometry intuition in learners
- Reinforces the key skills of graphing points, segments, and functions throughout the unit
- Lessons make for great supplements of existing curriculum or a full stand-alone unit
Cons
- No summative assessment available for lesson as a whole
- No answer keys provided
