What’s different about CCSS? These Standards are not intended to be new names for old ways of doing business. They are a call to take the next step. It is time for states to work together to build on lessons learned from two decades of standards based reforms. It is time to recognize that standards are not just promises to our children, but promises we intend to keep. — CCSS (2010, p. 5) Briars, June 2011 12

Fraction Equivalence Grade 4: – Explain why a fraction a/b = na/nb using visual models; generate equivalent fractions – Compare fractions with different numerators and different denominators, e. g. , by creating common denominators or numerators, or by comparing to a benchmark fraction such as ½.
