Circle Measuring Device – Degrees

Inclusive of all taxes

The Circle Measuring Device – Degrees is a precision-engineered metal protractor designed for use with Montessori circle fraction materials. This tool allows children to measure the angles of circle fraction pieces in degrees, helping them clearly understand the connection between geometric angles and fractional parts of a whole. As children align the fraction sectors with the protractor, they develop strong visual awareness of how circles are divided, further reinforcing concepts of rotation, angles, and proportional reasoning. This material is especially valuable in the elementary Montessori classroom, where learners transition from concrete fraction manipulatives to abstract geometry and angle measurement. With clear degree markings and a durable metal finish, it supports independent exploration, encourages accuracy in measurement, and helps children build confidence in geometric thinking and real-world math applications. Key Benefits & Learning Outcomes Helps children accurately measure circle fraction pieces in degrees Strengthens understanding of angles, fractions, and circle geometry Encourages independent learning through self-correction Builds visual–spatial reasoning and mathematical confidence Design & Material Material: High-quality, durable metal Markings: Clearly engraved degree indicators for precise angle measurement Function: Designed to measure Montessori circle fraction angles in degrees Age Group: 7+ years (Elementary level)
