Quadratic Formula and Imaginary Solutions Coloring Sheet
By Carol K.
A Halloween-themed coloring sheet paired with a short worked-example reading on solving quadratics with imaginary roots using the quadratic formula. Designed for 10th-grade Algebra 2 students, it reinforces discriminant analysis and simplifying expressions with i = √(-1).
Customize for your classroom
Teacher Guide & Tips
- Use as a low-stakes warm-up or end-of-week reward, with the worked example read aloud or silently before students color.
- Discussion question: Why does a negative discriminant guarantee two complex solutions rather than no solution?
- Scaffold for struggling readers: have them first identify a, b, and c on a separate scratch sheet, then check each step of the worked example before coloring.
- Extension for advanced students: ask them to find a quadratic with imaginary roots of 3 ± 2i and verify it by expanding.
- Estimated time: about 15 to 20 minutes, including the reading and coloring.
