This practice guide presents five recommendations intended to help educators improve students’ understanding of fractions. Recommendations include strategies to develop young children’s understanding of early fraction concepts and ideas for helping older children understand the meaning of fractions and the computations involved. The guide also highlights ways to build on students’ existing strategies to solve problems involving ratios, rates, and proportions.
Build on students’ informal understanding of sharing and proportionality to develop initial fraction concepts.
This practice guide was prepared for the WWC by Mathematica under contract ED-07-CO-0062.
