8th grade · Geometry
Verify experimentally the properties of rotations, reflections, and translations:
2 interactive, auto-graded activities for 8th grade students practising 8.G.A.1. 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.
Rotate shapes on the coordinate plane to discover how orientation changes while size and shape stay the same. In this interactive worksheet, students apply rotation rules for 90°, 180°, and 270° turns about the origin, record new coordinates, and visualize that rotations create congruent figures.
Students take control of a drone mapping a city festival to learn how translations work! They plot the drone’s flight path, move it to new coordinates, and verify that the triangles remain congruent after each translation. Through two real-world missions, students discover that translations slide shapes without changing their size, angles, or orientation—making them perfect examples of rigid motion.
