EdReady offers some math study components in Spanish.
EdReady does not have Spanish translations of English materials, but does provide supports that will be useful for teachers working with ESL (English as a second language) students and ELLs (English language learners). Please see more details HERE.

The default study tools include an alternate version of the Topic Text and Glossary in Spanish, and the Presentations are closed captioned in Spanish. However, all questions for the diagnostic, unit-level tests, and topic-level tests are in English.
