Gift 4 is only a slight variation on Gift 3, but the rectangular pieces open up many more possibilities. Children may view them as bricks or tiles and they will seem a familiar shape. The two inch cube is again divided into eight pieces, but the pieces have a proportion of 1 to 2 to 4 (1/2" by 1" by 2"). This feature will aid in creating modular constructions and designs, and proportion can be discussed as part of the Forms of Knowledge.
