8th grade · Geometry
Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.
2 interactive, auto-graded activities for 8th grade students practising 8.G.A.3. Mini Labs put the standard to work in a real scenario; Skill Practice builds fluency on the standard alone. Every one is randomized per student, so each learner gets their own numbers.
Dilate a Mini Park on the coordinate plane using a scale factor of 2! Students apply the rule (x, y) → (2x, 2y) to enlarge multiple park structures and watch the scaled map appear as they enter correct coordinates. A hands-on way to explore similarity, scale factors, and dilations in 8th-grade geometry.
Labs run 2 to 4 class periods and connect several standards into one project.
-Turn the Pythagorean theorem into a treasure hunt. In this story-driven Grade 8 lab, students decode a navigator's secret map, measure a hidden island, repair a ship, and triangulate buried treasure. Five auto-graded activities, ~4-5 class periods, covering 8.G.A.3, 8.G.B.6, 8.G.B.7, and 8.G.B.8. Run it right after introducing the theorem.
