Addressing the reality that English Language Learners (ELLs) need additional support in classes where math instruction is in English, this lesson-based series gives teachers the essential tools for meeting math content goals and language development goals simultaneously. With a deep appreciation for the unique linguistic experiences and diverse cultural traditions that ELLs bring to a classroom, each model lesson takes teachers step-by-step through ways to actively involve ELLs in learning math. Teachers will get a wealth of strategies and activities for modifying their instruction to improve the success of ELLs, suggestions for determining the linguistic demands of math lessons, answers to frequently asked questions including multi-language and multi-level situations, and instant-use reproducibles. Contents cover geometry, number sense, data analysis, algebra, and word problems.
