In this unit, students explore our numeration system in depth. Students begin by looking at patterns in our system and then work with other systems to help discover what constitutes a place-value system and a base system. By analyzing the structure of each system and comparing and contrasting different numeration systems, they will gain a deeper understanding of place value and bases and be able to justify why our system is both a place-value system and a base system.
