I am a white, cis-gendered female, social justice oriented high school math teacher who believes that love is love and that Black Lives Matter. Currently, I work at an arts magnet school in New Haven, Connecticut where I serve approximately 100 students. I am currently finishing my first year of teaching in New Haven although it is my 14th year of teaching overall. I have had previous experience at the high school level in The Bronx and at the middle school level in Philadelphia. This unit is intended for any educator interested in weaving number sense from a historical context into an Algebra I classroom using socially just pedagogy. As a member of a seven-person math department I have colleagues who teach similar sections of each of the courses I teach. Cooperative Arts and Humanities High School (CO-OP) is in downtown New Haven, Connecticut. The total 9th-12th grade student population is 630 with a 13:1 student to teacher ratio. More than 84% of the student body is part of the global majority. 66% of students are from low-income families and qualify for the Free and Reduced-Price Meals program. While at CO-OP students participate in one of six arts majors. Students spend 1.5 hours per day studying their major and have their other classes on a every other day block schedule. There is a 94% graduation rate. 34% of students who take AP exams pass and the school has a 24.3% on the College readiness index.16
