Champaign Unit #4

The case study examines the implementation of Everyday Mathematics, a comprehensive Pre-K–Grade 6 mathematics program aligned with the Common Core State Standards. The study focuses on Champaign Unit #4 School District, a large public school district in Champaign County, Illinois, serving 12 elementary schools across suburban and rural areas. The district enrolls 10,060 students, with 55% classified as low-income and 10% as limited English proficient.  

Champaign Unit #4 adopted Everyday Mathematics in 2015 to enhance math instruction and align with rigorous Illinois Learning Standards. The program employs a spiral curriculum and distributed practice methodology, which revisits key concepts in varied contexts over time to promote long-term mastery. Outcomes were measured using state summative assessments (PARCC), comparing student performance before and after implementation.  

Results showed steady improvement in math proficiency across Grades 3–5. Between 2015 and 2016, the percentage of students meeting standards increased substantially: Grade 3 (34.4% to 40.3%), Grade 4 (30.1% to 38.2%), and Grade 5 (29.6% to 38.2%). By 2017, Champaign students performed at or above statewide averages in math proficiency. For example, Grade 5 students outperformed their peers statewide (33.3% vs. 29.5%). Teachers and administrators credited the program’s alignment with standards, clarity in instructional design, and professional development support for these outcomes.  

The report highlights the district’s collaborative partnership with McGraw Hill, which provided ongoing training and access to program authors.
