# Shape sorter: basic shapes: pairs

TLF ID L10331

Help sort pairs of shapes in the Shape factory. Examine examples of basic shapes that belong in the Yes set. Examine examples of basic shapes that do not belong in the set. Work out what features of the shapes are important and test your ideas by sorting some shapes. Then program the robot and see if it sorts the shapes correctly. This learning object is one in a series of six objects. Two objects in the series are also packaged as a combined learning object.
