NCTM Dynamic Angle Project

Erell Germia, Apr 29, 2024

This module includes interactive tools for elementary students to explore and make mathematical meanings about dynamic angles. Dynamic angles integrates multiple natures of mathematics of angles such as its qualitative nature (an angle as a union of two rays), quantitative nature (an angle with measurable attribute illustrated by a wedge), and multiplicative nature (an angle as an iterative amount of rotation).
