Description
Developing Fractions Sense B
Students develop an intuitive understanding of fraction size relative to a benchmark and learn several strategies for adding and subtracting mixed fractions having a common denominator.
The Developing Fractions Sense Student Workbook B consists of 45 short lessons focusing on the 4th-grade fraction standards. 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.
Students learn strategies for comparing fraction size relative to a benchmark, e.g., 4/3 vs. 3/4 relative to 1, and 7/12 vs. 6/10 relative to 1/2. They also learn to subtract mixed fractions both by borrowing and making an exchange and by converting to improper fractions. Other lessons deal with multiplying a fraction by a whole number and verbal problems having fractional relations.

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.
