#### Fraction Operations and Initial Decimal Ideas

This is a series of lessons from the Rational Number Project (http://www.cehd.umn.edu/ci/rationalnumberproject/rnp2.html) including teacher notes, activities ready to be copied. The Rational Number Project (RNP) is a cooperative research and development project funded by the National Science Foundation. Project personnel have been investigating childrenâ€™s learning of fractions, ratios, decimals and proportionality since 1979. This book of fraction lessons is the product of several years of working with children in classrooms as we tried to understand how to organize instruction so students develop a deep, conceptual understanding of fractions. You may pick and choose the lessons that you would like to try and do not need to complete them all in order.
