New York City Selects Houghton Mifflin Harcourt’s GO Math! As Recommendation for Elementary Math District-wide

NEW YORK – Global education leader Houghton Mifflin Harcourt’s (HMH) comprehensive  Common Core aligned mathematics program, GO Math!, has been selected by the New York City Department of Education as a recommended curriculum for grades K-5.  As one of the elementary math programs endorsed, GO Math! will be used widely throughout the district, which serves about 1.1 million students in over 1,800 schools, in classrooms starting this fall. 

Specifically written to provide thorough coverage of the Common Core State Standards (CCSS) with an emphasis on depth of instruction, GO Math! provides exceptional support for students and teachers as they work to meet the mathematics standards’ objectives.  Lessons begin with concrete, context‐based situations and, through the use of models, math talk, sample questions and other tools, progress toward more abstract problems, creating a natural, progressive learning environment to help students successfully engage with complex ideas.  

“New York City is leading the charge in ensuring that its schools are well-equipped with best in class curricula, professional development tools and a broad spectrum of community resources to support teachers, administrators, students and parents throughout the transition to Common Core-based learning,” said Linda K. Zecher, President and Chief Executive Officer, HMH.  “We are immensely proud that GO Math! has been designated as the highest quality elementary math curriculum, and that the program’s resources will aid the city in a successful implementation process that will serve as a positive model for districts throughout the nation.”

New York City is the first and largest urban school district to recommend Common Core aligned curricula for use in its schools. The Department of Education conducted a thorough review of numerous programs in order to select the highest quality materials for endorsement.  Using the “Publishers’ Criteria,” a set of rigorous guidelines intended to aid curriculum developers in aligning materials to the Common Core, teacher-leaders from across the city worked with central staff to evaluate a wide array of programs.  

GO Math! received the top scores on the Publishers’ Criteria rubric, garnering praise for its depth of instruction, equal emphasis on conceptual understanding, procedural fluency and a focused and coherent articulation across grade levels.  Based upon feedback from the New York City Department of Education’s review, HMH is now working closely with district administrators on specialized GO Math! program components that directly support the unique curriculum needs of New York City’s students and teachers, including performance tasks at each grade-level with scoring rubrics and samples of student work for teachers to reference.
