Suggested pacing
Use approximately 10 sessions: concept development, guided practice, application, error analysis, mastery, corrections, and project evidence. Adjust by demonstrated mastery rather than age.
Instruction, differentiation, and records
Nonlinear Systems & Matrices
How can multiple equations, matrices, and graphical intersections describe systems with several interacting constraints?
Three pathways
Foundation: prerequisite retrieval, scaffolded steps, tables and graphs. Core: complete unit targets. Extended: proof, parameter analysis, modelling, and pre-calculus connections.
Assessment evidence
Use lesson checks, practice explanations, the randomized mastery check, corrections, project rubric, oral explanation, and representative work together. Do not infer mastery from one score alone.
Key misconception
Reporting x-values without corresponding y-values.
Require the learner to identify the first invalid step and provide a rule, verification, or counterexample.
