Reply To: Lesson 3 – Why The Unit Of Measure Matters – Discussion

[John Sasko]

“Numeral responses alone are not enough.”

Quantity has a context…

The idea of iterating and partitioning in fractions is something I learned from Marian Small’s work and it has helped me a great deal when working with teachers and students.

Division of fractions! You need to have a firm grasp of unit to be able to think through these problems. One half divided by three-fourths? How many units of three fourths are in one-half? Two thirds of a unit that is three-fourths. The language gets messy to write/type, but you have to be clear when expressing the relationship.
