(3) 4-6 Illustrated by Bill Slavin. Upper-elementary math fans (and teachers) will enjoy the many hands-on activities in this compilation of Ross and Slavin's three earlier books about squares, triangles, and circles--and their related solid shapes.

Chapters include diagrams and cartoonlike illustrations. Glos., ind.
