AREA MODEL
AREA MODEL
- Topics Addressed
- partition wholes into equal areas
- fractions are represented as parts of an area or region.
- useful manipulatives include rectangular, or circular fraction sets, pattern blocks, geoboards and tangrams.
- compare fractions by reasoning about their size
- Interactive Games
- Modeling Fractions
- Comparing Fractions
- Equivalent Fractions
- Fractions Greater than One
- Adding and Subtracting Fractions
- Multiplying Fractions by Whole Numbers

Shake and Number BondLINEAR MODEL
LINEAR MODEL
- Topics Addressed
- lengths are compared instead of areas (e.g., 3/4 of an inch).
- either number lines are drawn and subdivided or physical materials are compared on the basis of length.
- useful manipulatives include cuisenaire rods, fraction strips, number lines and trains built from different colored unifix cubes.
- Interactive Games
- Equivalent Fractions

SET MODEL
- Topics Addressed
- the whole is understood to be a set of objects, and subsets of the whole make up fractional parts (e.g. ½ of the class, ¼ of a set of buttons, 1/3 of a tray of muffins).
- useful manipulatives include two-color counters, centimeter cubes, or any set of objects that can be counted (e.g. a bag of marbles).
