Blue Longs(set of 10)

The newest concept in Base Ten Blocks. These red and blue transparent blocks are interlocking. Ten flats will lock together to make 1000 units visible. Students will be able to lock blocks together to form interesting structures as well as locking units to make longs, longs to make flats, and flats to make cubes. Excellent for algebra students who need to see negative values. Great for the overhead projector.
