Variations and Extensions

There is a very different and separate presentation for this work at the elementary level. AMI albums do not have a primary level presentation on this material.

In elementary, children work with dividing fractions by fractions using these fraction skittles. They are quickly introduced to the concept of which is which (what is described here as the "primary presentation", and they catch on quickly. The primary presentation does not seem necessary.
