Illustrative Mathematics vs Khan Academy

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.
