## Description

An inquiry-based approach to this course allows future teachers to learn through exploration and group work, leading to a deeper understanding of mathematics. Known for her contributions in math education, **Sybilla Beckmann** writes the leading text for this approach. In Mathematics for Elementary Teachers with Activities, students engage, explore, discuss, and ultimately reach a true understanding of mathematics.

The **Fourth Edition** provides a new full-color design, making the math come alive. For the first time, the content and activities are combined into the same text, creating a self-contained resource for this course and beyond. Common Core State Standards are integrated to complement the National Council of Teachers of Mathematics (NCTM) Focal Points and Standards that appear where appropriate. New *From the Field* features highlight the latest research, *Integrating Mathematics and Pedagogy* (IMAP) videos (available separately), children’s literature, views from the classroom, and lesson planning to prepare future teachers for their teaching careers.
