This math error analysis activity will make your students really think about slope. Students identify incorrect statements about slope shown on graphs, in tables and in ordered pairs. Students are then asked to fix each error.
On each card there is a graph, a table and a pair of coordinates, as well as 3 statements about each representation's slope. 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 reading graphs and finding slope from tables and ordered pairs. It also offers practice recognizing errors when they occur.
There are 10 cards, a student answer sheet and an answer key included.
