This card game (created on Word) is a printable activity that has many uses. There are 20 cards with pictures of angles on a protractor. There are 20 cards with the measurement of the angle to match up to the pictures. There are additional cards included that just say Acute, Obtuse, or Right Angle that can also be copied and used. My thought was to deal out the 20 angle picture cards and put the measurement (answers) cards in a pile. Students pick a card from the top of the pile and try to make a match with an angle picture in their hand. It can also be played like a memory game and to make it more difficult, you could copy the additional Acute, Obtuse, Right angle cards and they would have to make a 3 way match for points. Each matched set also has a point value so students can add their points to determine winner. I would recommend copying this on card stock. Could be used all year...and for many years to come. This skill never changes.
