Equivalence is a concept that comes up across the entire K-12 grade span and in many different areas of mathematics. Students who are bureaucratically designated as "English Learners" can explore equivalence across their K-12 academic careers while developing language to connect ideas. Drawing on what is known generally from theory and research about equivalence, this brief identifies what educators can do to challenge and support English Learners in this area. The ideas explored in this brief emerged from field trials of a summer bridge program designed to challenge and support rising 9th grade students making the transition from middle to high school. The authors of this brief were part of the team that developed the bridge program, Reimagining and Amplifying Mathematics Participation, Understanding, and Practices (RAMPUP), through the National Research and Development Center to Improve Education for Secondary English Learners at WestEd. Drawing from the RAMPUP field trials, this brief gives examples of students' reasoning about and explorations of equivalence, and provides three specific actions that educators can take specifically to support English Learners.
