This interactive activity allows students to demonstrate their understanding of right, acute (less than right) and obtuse (greater than right) by sorting angles into the correct columns. This activity also includes an image select game. A variety of angles (mathematical and real life) flash on the screen. The student touches the flashing screen and 3 answers appear. The student must determine whether the picture of the angle is right, acute or obtuse. This activity could be used individually, small group or whole class.
