- Straight edge
Cut strips of chipboard 1" x 8". Use an ordinary paper cutter. Young children (Grades K-4) find 12" or longer wood rulers unwieldy. It is best to involve children in making their own tools.
- Compass or Circle-maker
Caliper-style compasses are recommended for ages 12 and older. Simple translucent plastic circles like the lids of coffee cans or margerine contains provide more than adequate single radius arcs and circles. Opaque lids should not be used because it's necessary to see through the plastic to align the circumference with a given point as its center.
- Sets of colors (3-4 per student or group of students)
Color markers work best, though crayon pencils will do.
- Pencils and Erasers, Scissors and Glue
HB and 2H pencils, kept at a sharp point; scissors for right- and left-handed children. Elmer's glue or a clear liquid glue with a sponte-tip dispenser works well for most projects described in these pages.
- White Bond Paper, Tagboard, Drawing Paper, Colored Construction Paper
Fine worksheets can be reproduced from the sketches provided with these pages; less fine drawings may be printed out directly from your graphical Web browser. A hard-copy booklet of copier masters may be obtained by writing to Norman Shapiro; be sure to include your postal address. Use 8-1/2" x 11" copier papers. In some cases, heavier weight drawing papers or tagboard are best for polyhedron constructions that are to be cut and folded. Colors show best on better quality papers.
- Sets of Photocopied Worksheets
Keep on hand a set for a whole class, plus half as many again to accommodate students who need an extra sheet or two. Especially at the outset, some projects require two or more sheets per student.
