The Zeroing in on Number and Operations series features easy-to-use tools for teaching key concepts in number and operations and for addressing common misconceptions. Each book in the series, which is organized by grade level, provides thirty research-based, classroom-tested modules that zero in on the key mathematical strategies and concepts essential for that grade level while highlighting the importance of teacher language in the development of those skills.
The spiral-bound, flipchart format makes it easy to access the important sections in each module, including:
-
Summaries that identify the mathematical focus and associated challenges and misconceptions
-
Instructional strategies and activities that develop conceptual understanding and computation skills
-
Activities and ideas for adjusting activities to meet individual needs
-
Reproducibles for instructional use
-
Resources for further reading
