Math encompasses language and gives learners the skills and confidence they need to succeed in the workforce and higher education. This is the first of a series of courses designed for ESOL teachers who would like to deepen their understanding of math and learn how to integrate math and numeracy skills in their ESOL classrooms. Lessons provide conceptual understanding of math topics around whole numbers, including cultural differences in procedures and notation, and offer strategies for making math accessible for all levels of ESOL learners.
