When teachers talk with students about their number sense and computational skills, they're bound to uncover some surprising gaps in their understanding. Knowing how to identify and bridge those gaps is essential for helping students at all levels advance as mathematical thinkers.
The Zeroing in on Number and Operations series, which aligns with the Common Core State Standards and the NCTM Standards and Focal Points, features easy-to-use tools for teaching key concepts in number and operations and for addressing common misconceptions. Sharing the insights they've gained through decades of mathematics teaching and research, Anne Collins and Linda Dacey help you focus on what students really need to know and understand at each grade level.
The 30 modules for Crades 7-8 are organized into three sections: Number Theory and Integers, Fractions, Decimals, Percents; and Ratio and Proportionality. Each module begins with the identification of its Mathematical Focus and the Potential Challenges and Misconceptions associated with those ideas. In the Classroom then suggests instructional strategies and specific activities to implement with students. Each activity is supported by a reproducible (located in the appendix). Meeting Individual Needs offers ideas for adjusting the activities to reach a broader range of learners. References/Further Reading provides resources for enriching your knowledge of the topic and gathering more ideas.
