How this resource helps
Test supporting-line behavior, segment-length scaling, center-distance scaling and angle preservation under positive-factor dilations. Construct and measure enlargements and reductions with a ruler and protractor; keep actual observations separate from ideal predictions. Includes nonorigin centers, the identity case, the fixed center, units and measurement uncertainty. Build understanding through warm-ups, teacher modeling, guided practice, collaborative practice, independent work, targeted reteaching, and exit tickets. A suggested three-session teaching path organizes learning targets and task selection; the full 60-task bank is reusable across additional meetings and is not a requirement to complete every task in three days. Each task is mapped to a learning target. Teacher keys explain reasoning, and multiple-choice keys discuss all answer alternatives. This course-based high-school NC Math 2 packet is not restricted to a single grade. Customer ZIP contains the same approved PDF only. No editable Word file is included. All 142 pages are available in the preview.

Standard or objective
NC.M2.G-SRT.1 NC.M2.G-SRT.1a: Construct and compare segment images, distinguishing same supporting lines from distinct parallels and the identity exception. NC.M2.G-SRT.1b: Measure corresponding segment lengths and verify the image-to-original scale factor using consistent units. NC.M2.G-SRT.1c: Construct points on center rays and measure scaled center distances, including the fixed center without dividing by zero. NC.M2.G-SRT.1d: Measure corresponding angles to test preservation under enlargements and reductions, with honest records and stated uncertainty. Course-based high-school standard; not assigned to a single grade.
