The Fraction Modeling Pattern Block includes only the pieces that are fractions of the hexagon. The hexagon, blue rhombus, red trapezoid, and the green triangle like standard pattern block sets are represented with these sturdy cardboard cut-outs. Two additional fraction pattern blocks are included. The brown pieces represent fourths of the hexagon. A purple piece represents 1/12 of the hexagon.
These are not recommended as your primary pattern block set since it lacks the square and the tan parallelogram. Plus, they are made out of a thin cardboard and may be difficult for younger students to pick up.
Nevertheless, they are an inexpensive set that you can even use with other pattern blocks because they are based on the same 1" sides standard.
As a fraction set, they model the whole (hexagon), 1/2, 1/3, 1/4, 1/6, and 1/12.
The set includes over 200 pieces.
