Complete instructional sequence
Detailed Lessons
Lessons include objectives, formulas, concept development, worked examples, guided and independent practice, differentiated pathways, application, misconception analysis, mastery evidence, reflection, and local completion.
Graphical Solutions of Linear–Nonlinear Systems
A system may have zero, one, or several solutions. Graphing gives estimates and structural insight; exact algebra confirms when possible.

Lesson 02Solving Nonlinear Systems by Substitution
Substitution reduces a nonlinear system to one equation. Each resulting input must be paired with its output and checked.

Lesson 03Polynomial, Rational & Radical Systems
Polynomial, rational, and radical systems may create extraneous candidates or high-degree equations. Technology can support but not replace verification.
Open detailed lesson
Lesson 04Matrix Vocabulary, Dimensions & Operations
Matrix dimensions control which operations are defined. Multiplication is not generally commutative and represents composition of transformations or linked systems.
Open detailed lesson
Lesson 05Matrix Equations, Row Reduction & Systems
Augmented matrices organize elimination. A row of zeros may signal dependence; an impossible row signals inconsistency.

Lesson 06Determinants, Inverses & Transformation Models
The determinant indicates invertibility and area-scale behavior for 2D transformations. Inverse matrices reverse nonsingular linear transformations.
