Cuisenaire Workbooks 1- 6 by C Gattegno
For use with textbooks I & II
These six booklets contain over 1400 problems. The area of mathematics covered is appropriate to the work generally tackled in the primary school. Older children, especially those who may not yet have a firm grasp of mathematics will also find themselves challenged by the whole range of problems and gain a better understanding of the subject by tackling the workbooks in association with Cuisenaire Rods.
