TED-Ed: One is one or is it? - Christopher Danielson

The video tutorial explores the concept of units in mathematics, emphasizing the importance of understanding what constitutes 'one' in different contexts. It explains how units can be composed and partitioned using everyday examples like apples, eggs, and toaster pastries. The tutorial highlights the significance of units in understanding whole number and decimal place values, as well as fractions. It concludes by relating these ideas to mathematical concepts, illustrating how numbers like 10 and 100 can represent different quantities depending on the unit.
