Education device
First Claim
1. An educational game comprising in combination a planar base, a plurality of shaped blocks detachably securable to said base and means to secure a selction of said blocks to said base to form digital type numbers from 0 to 9 inclusive, said blocks including at least three individually shaped blocks, an upper and lower transversely situated block, a centrally located transversely situated block and a side vertically situated block, said upper and lower transversely situated block being of a substantially rectangular cross sectional configuration having a first horizontal face and a second spaced and parallel horizontal face, and a first vertical face and a substantially spaced and parallel second vertical face, said first vertical face being longer than said second vertical face, the ends of said block angulating inwardly at a similar angle from the ends of said first vertical face to the ends of said second vertical face thereby defining a trapezoid.
