Instruction, differentiation, and records

Rational Expressions, Equations & Functions

How do excluded values, asymptotes, holes, and rates of change shape rational expressions and models?

Suggested pacing

Use approximately 15 sessions: concept development, guided practice, application, error analysis, mastery, corrections, and project evidence. Adjust by demonstrated mastery rather than age.

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

Canceling matching terms across addition or subtraction.

Require the learner to identify the first invalid step and provide a rule, verification, or counterexample.
