This document includes instructional tips on: (1) Building on students' informal understanding of sharing and proportionality to develop initial fraction concepts; (2) Helping students recognize that fractions are numbers that expand the number system beyond whole numbers, and using number lines to teach this and other fraction concepts; (3) Helping students understand why procedures for computations with fractions make sense; and (4) Helping students develop proportional reasoning skills before exposing them to cross-multiplication. It provides educators with how-to steps for carrying out these evidence-based recommendations from Institute of Education Sciences Educator's Practice Guides. The tips translate these recommendations into actions that educators can use in their classrooms. These tips are supported by research evidence that meets What Works Clearinghouse design standards and are based on a practice guide authored by a panel of experts.
