Measuring and understanding units of measure, such as inches, centimeters, degrees, pounds and miles is an interesting concept for children to grasp. Think about it, it’s a lot. Encourage them to become familiar with the tools to help them succeed in the classroom. Included here is a 6” clear plastic ruler and a protractor. The protractor fits in the contour of the arc in TemplaytesⓇ Yellow Puzzle. Children learn through open-ended exploration. Allow them to play with measuring lengths and angles, counting the numbers, noticing the equal increments. Support STEM fields and get kids excited about math!
