Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 6–7 Professional Commentary: Students can better understand the algorithm for dividing fractions if they analyze division through a sequence of problems starting with division of whole numbers, followed by division of a whole number by a unit fraction, division of a whole number by a non-unit fraction, and finally division of a fraction by a fraction. A lengthy list of guiding questions, summary questions, an assessment task, a lesson extension, and a set of carefully sequenced activity sheets are included.... Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 8–9 Professional Commentary: Students will investigate the input/output model for building function tables. Then they will connect tables, graphs, function rules, and equations in one variable....
