How this resource helps
Determine amplitude, midline, range and period from sine parameters and graphs. Use reproducible technology investigations to isolate and explain effects of a, b and h. Build and interpret sine models of periodic phenomena using contextual units and timing. Check angle mode, graph windows, model limitations and exceptional cases. The suggested 3-session pathway covers: Parameters and radian-mode evidence; Periodic models in context; Validate technology and model limits. Seven instructional sections move from warm-up and modeling through guided, collaborative and independent practice to small-group reteach and exit tasks. Select tasks based on student evidence; the reusable 60-task bank is not intended to be assigned in full within the suggested sessions. Require the model or settings, angle unit, a numerical trace/table or labeled sketch, a parameter explanation and a contextual check. Separate a viewing-window error from a model error. Record first independent reasoning before supplying a worked key. Download contains one 124-page PDF in a ZIP. No editable Word or PowerPoint files are included. Course-aligned, not an invented grade-specific standard. Review the full SAMPLE-watermarked preview before purchasing.

Standard or objective
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.
