These 1930s Math Game Boards and Cards consist of six 8.5" x 6.5" heavy cardboard game boards and 54 heavy cardboard game pieces. Each board has nine squares, each with half an image of an object and an = sign with a number. Each game piece has the other half of the object and two numbers with either a +, - or x sign. The illustrations are all in a palette of oranges, blues and off-white. Manufacturer and exact age are unknown, although the styles of the objects suggest that this was probably produced in the 1930's. There is no game box. These 1930s Math Game Boards and Cards are in very good condition with some very minor staining to the surfaces and several very small edge dents.
