EL Education Curriculum vs Illustrative Mathematics

EL Education Curriculum is a free, web-based K–8 Language Arts curriculum for educators and schools. It is standards-aligned and includes teacher tools and built-in assessments. The design draws on the science of reading and the science of learning and development. Students use complex, grade-level texts by diverse authors while building science and social studies knowledge. Original research and interdisciplinary investigations develop inquiry, analysis, critical thinking, and craftsmanship. Differentiated opportunities address English language learners, economically disadvantaged students, students with disabilities, and advanced learners. Connections to students’ communities support compassionate leadership and thoughtful citizenship. Grade-level index pages provide downloads such as Teacher’s Guide PDFs and Teacher Supporting Materials or Student Workbook Word documents. Creating an account provides access to hundreds of free resources. EL Education offers coaching and strategic planning for guided curriculum pilots. The digital resources plan costs nothing; some resources require an account. A 2025 K–5 professional learning course costs $350, paid once and provides 365-day access.

Illustrative Mathematics provides IM Math, a problem-based core mathematics curriculum for transitional kindergarten through grade 12. The IM Math v.360 sequence runs from transitional kindergarten through Algebra 2. Lessons ask students to solve meaningful problems, explain their reasoning, compare strategies, and connect mathematical ideas across lessons, units, courses, and grades. Built-in resources include discussion routines, support for English learners and students with disabilities, unit assessments, session checkpoints, and lesson cool-downs. AccessIM provides the complete curriculum online for free, with implementation resources and downloadable, printable PDFs for teachers and students, without a time limit. The curriculum aligns with the Common Core State Standards for Mathematics. Schools can obtain print materials and enhanced digital platforms through IM Certified partners such as Imagine Learning, Kendall Hunt, and Kiddom. Partner platforms may add rostering, assignments, reporting, and progress monitoring.
