A matching task designed to develop fluency in finding the area and perimeter of circles. There are three cards that do not match the rest of the cards. An extension is to make the cards that fit these distracters; in some cases this will require starting with the circumference or the area and working backwards.
Answers are provided for the matching pairs.
The print out for the matching task is pre-jumbled so you do not need to worry about cutting them out prior to the lesson.
