Teaching Fractions with Understanding: In addition to those listed above who are the currently the most active members of the RNP, several past and current graduate students have also contributed to our work. Discrete wholes - sweets, marbles, cherries, beads etc. So, sharing three chocolate bars between four children would be achieved by first halving all the bars. For example with the very young, it might be necessary to begin with a number-free approach;.Introduction to Part Part Whole
Fractions as operators. This might be achieved through questions inviting learners to describe the same fraction in different ways or by identifying problems with equal answers. In fragmenting the child treats the parts as individual unit items.

The part-whole use of fractions applies in other practical contexts involving physical quantities, such as length, volume and groups of objects.
Same denominator. Finally, we look at some ways of teaching fractions more effectively that arise from Grace's work.
At this point a teacher might ask the child "How much has each person got? We have been fortunate to have had many productive groups of faculty and graduate students working together at different stages of this project. Chelsey Fagerlund, Ph. Dynamic fractions.
