How this resource helps
An original technology-based sine-modeling lesson interpreting amplitude, period, frequency and vertical position, including parameter experiments, negative/zero cases and contextual model limitations. Standard NC.M3.F-TF.5: Use technology to investigate the parameters, 𝑎, 𝑏, and ℎ of a sine function, 𝑓(𝑥) = 𝑎 ∙ 𝑠𝑖𝑛(𝑏 ∙ 𝑥) + ℎ, to represent periodic phenomena and interpret key features in terms of a context.
What’s Included
- One editable 16:9 PowerPoint with 35 slides and teacher speaker notes on every slide.
- Full standard and all its subparts, unpacking, essential question, learning goals, warm-up, vocabulary and teaching routine.
- Five worked models, guided practice, partner work, five scored independent items, small-group intervention and an open extension.
- Matched blank/completed guided notes, a three-item exit ticket and reflection.
- Editable mathematical diagrams, tables and graphs where relevant. Graphing calculator or spreadsheet activities are included where required by the standard.
