Great analysis activity for students. Four problems on each page, 3 of which have the same answer. Student work to identify which problem does not fit with the others and to explain why. Good activity for use as a review, warm up or as part of an assessment.
Resource includes 12 different sheets: 3 pages each of 4 different levels of difficulty. The first level requires knowledge of theorem, Level two : two steps Level 3: Pythagorean Theorem Level 4: Pythagorean Theorem plus one step.
When I have used in the classroom, I demonstrate with one of the pages and double side the other two in a version for the students.
