Effective mathematics teaching promotes understanding, which provides a sound basis for skill development, all resulting in better learning retention.

Designed with a user-friendly format, the authors of this resource stress that when mathematical information is connected to what students already know about mathematics, it is easier for them to learn and recall. To that end they present the development of mathematical content based on a small number of easy-to-understand and easy-to-teach "big ideas."

The book emphasizes that effective mathematics teachers plan lessons that include a more complete development of mathematical ideas, use visuals supporting mental imagery, present opportunities for kinesthetic learning activities, provide chances for children to communicate their understanding of mathematics, and allow for continual monitoring of student learning. Lessons include straightforward, easy-to-use learning activities illustrating specific mathematical concepts and skills, visuals to help develop mental imagery, and opportunities for active student learning.
