Developing Fractions Sense B

Every new concept or skill is introduced concretely using fraction blocks, or visually using rectangular grids, before the student is provided with the symbolic or arithmetic approach. This concrete-to-symbolic approach enables conceptual learning. The focus of the program is on addition and subtraction of mixed fractions having a common denominator, comparing fractions using benchmarks, and multiplication of fractions by a whole number.

Besides its intended use with 4th-grade students, the workbook may also be used with 3rd-grade gifted students and 5th or 6th-grade students who lack a solid foundation in fractions.
