Eight core concepts form a trajectory of learning that moves generally from foundational to more complex ideas. The trajectory is designed to help students form strong schemas and mental representations of fractions, allowing them to work with increasingly difficult fractions ideas with understanding. This resource will help students to develop a deep understanding of unit fractions (the base of all fractions); and the eight core concepts (the keys to unlocking fractions understanding). For educators, this resource will help you to assess students’ understanding and possible misconceptions via the use of targeted, field-tested questions and recommended next steps that reveal student understanding; and respond to student needs (with precise and differentiated tasks and instruction).
