This course is in two parts. Today
we focus on pre-fraction ideas
i.e. ideas learnt in the early
grades which are important in
the learning of fraction as well as
basic concept of fractions. We
will also examine fraction topics
typically taught in lower primary
levels i.e. grades one to three.

We discussed visualization and looking for patterns. Also we discussed generic competencies including
metacognition and collaboration.
