Sights, Sounds, and Symbols is a professional development resource that provides activities on the history of numbers and number systems. This resource was created and designed to deepen understanding of our Hindu–Arabic system by investigating many different concrete (sight), spoken (sound), and written (symbol) number systems, and examining past methods of calculating.
Sights, Sounds, and Symbols has easy-to-read information and a wealth of activities that together will make it a valuable resource for every middle to upper primary school teacher.
