A focus on ratios and proportions : bringing mathematics education research to the classroom / Marjorie M. Petit, Robert E. Laird, Matthew F. Wyneken, Frances R. Huntoon, Mary D. Abele-Austin, and Jean D. Sequeira. - 1 online resource (xiii, 225 pages) : illustrations - Studies in mathematical thinking and learning .
Understanding ratio, rates, and proportions -- Deepening understanding of ratio and proportion concepts -- Understanding the OGAP proportionality framework and progression -- Using the OGAP ratio and proportion progression to inform instruction and student learning -- Structures in proportion problems -- Structures in ratio and rate problems -- More problem contexts -- Understanding the cross products procedure -- Percents-building understanding, flexibility and fluency.
"This resource offers a groundbreaking effort to make mathematics education research on ratios and proportions readily accessible and understandable to pre-service and in-service teachers of grades 6-8. Using extensive annotated samples of student work and based on research gathered in the Ongoing Assessment Project (OGAP), this engaging, easy-to-use book teaches readers how students develop understanding and fluency involving ratio and proportion concepts. Each chapter includes student work samples to illuminate the research, guidance on CCSSM standards, end of chapter Looking Back questions, and Instructional Links that help teachers relate concepts back to their own instructional materials"--
