The idea of defining the unit in order to measure the quantity really resonates with me. This concept came to life for me when I took Graham Fletcher’s Foundations of Fraction course. When we can encourage students to measure a quantity of something but in different ways( changing the size of the unit) when can move them to think more flexibly.

I never realized before that I did this back when I taught fractions in Grade 4 (9-10 year olds) using pattern blocks. When we defined one as being the yellow hexagon we limited ourselves to just working with halves, thirds and sixths but when we defined our unit as 2 hexagons, then we were able to explore fourths and eighths.

It’s the same thing with using base-10 blocks. If the cube is always “one” then we can only use that resource in just one way. But if the hundreds flat is defined as “one” then we can use those materials to explore decimals.
