Sub-goal D: Create and use unit fractions as measures
Fractions as measures comes from knowing fractions as quantities being produced from iterations (i.e., connected copies) of a unit fraction. A unit fraction becomes known as having a 1 to n multiplicative relationship with the whole. Unit fractions then become fractional units that are the building blocks for other fractions. This can be the basis for determining a unit fraction from a given whole, re-creating the whole from a unit fraction, and creating non-unit fractions from a unit fraction. Fractions as measures also provides the basis for fractions on a number line. The instructional resources provide opportunities for students to engage with fractions as measures.
