The Rational Number Project (RNP) advocates teaching fractions using a model that emphasizes multiple representations and connections among different representations. Fraction Operations and Initial Decimal Ideas includesincludes: (a) a module of 28 lessons related to fraction operations, decimal concepts, order, equivalence and operations with decimals (addition/subtraction); (b) strategies to deepen student understanding as they develop meaning and procedural skill with fraction operations and initial decimal ideas; (c) understanding of the support teachers in urban settings need to teach RNP curricula effectively; (d) an online professional workshop to prepare teachers to use this new module.

The Rational Number Project (RNP) advocates teaching fractions using a model that emphasizes multiple representations and connections among different representations.
Initial Fraction Ideas include developing meaning for fractions using a part-whole model, constructing informal ordering strategies based on mental representations for fractions, creating meaning for equivalence concretely, and adding and subtracting fractions using concrete models. Initial Fraction Ideas do not include formal algorithms, and instruction with formal algorithms was not part of this original RNP curriculum module.
