This geometry error analysis algebra activity will make your students really think about geometric transformations in the coordinate plane. Students identify incorrect statements when presented with rotations, translations and reflections, then fix each error on their answer sheets.
Problems include:
translate up/down, left/right,
reflect over x-axis, y-axis, y = x,
rotate 90 degrees clockwise/counterclockwise about the origin,
rotate 180 degrees.
On each card is a shape to transform and 3 statements. Students need to figure out which of the 3 statements is false (the "lie"), then correct the false statement on their answer sheet.
This activity gives students practice transforming shapes in the coordinate plane, and with recognizing errors when they occur.
There are 10 cards, a student answer sheet and an answer key included.
