Come one, come all! This circus-themed geometry game provides a unique and entertaining way for fourth graders to practice estimating and measuring angles. In order to help the circus clowns hit the target, young mathematicians must identify the angle and aim the cannon correctly before sending Bozo flying across the tent. Perfect for students working on lines and angles, Circus Angle Measurement is a fun way to help kids grasp benchmark angles, such as 30, 90, or 180 degrees.
