Fraction Number Sense

Definitions

Number sense – an intuitive feel for numbers and their relationships – develops when children solve problems for themselves.

“Number sense” describes a cluster of ideas, such as the meaning of a number, ways of representing numbers, relationships among numbers, the relative magnitude of numbers, and skill in working with them… In a problem-centered mathematics curriculum, number sense is closely tied to problem solving, as the children described above show. These children have learned, over time, that they are capable of solving problems and that they can play with numbers to make sense of a problem. They have used their growing number sense to develop strategies to help them solve problems.”

Fractions

“Fractions are often a difficult concept for young learners to grasp. Keeping it concrete is a great first step, until they understand that fractions really just mean it’s a part of the whole.”—Deb Russell
