Introduce early math concepts to your students with this horizontal abacus. Perfect for teaching numeration, addition, subtraction and multiplication, ten rows of five yellow and five blue beads slide along metal rods; place value markers are printed along one side of the plastic case. The frame is thicker than the beads, allowing it to lie flat on desks. Grades K+. 8 1/2' L x 9 1/2' W x 1/2' H.
