The volume explains critical math areas in which many students have difficulty—early numeracy, time and money measurement, number combinations, fractions, word-problem solving, algebra, and more. Leading experts describe relevant standards and show how to use data-based individualization to plan, monitor, and intensify instruction in each area. Beginning with bulleted guiding questions, chapters feature a wealth of evidence-based intervention strategies, lesson-planning ideas, and case examples. Reproducible instructional activities and planning forms can be downloaded and printed in a convenient 8 1/2" x 11" size.
