The Council of the Great City Schools, Illustrative Mathematics, and Achieve collaborated on the development of an online professional development module to deepen understanding of the fraction progression across grades 3-5 - a critical focus in the college-and career-readiness standards.  Access to available materials is provided through the Illustrative Mathematics website using the links below:
