Sum Time! Self-correcting tiles and cards make learning easy. Sum Time

self-correcting as it is impossible to place a tile on the wrong
square. The base cards give plenty of exercises in arithmetic.
The case is
durable and can be carried easily. Once in place, the tiles are
secure. The case is also used to display the cards.
