Exponential Functions & Growth Models

How do repeated multiplication, percent change, and continuous growth create exponential patterns and decisions?

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

Reading b=0.8 as 80% decay; it represents 20% decay.

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