Dale Seymour Publications: Has a math curriculum for the elementary
which includes a version of Logo called Geo-Logo. It is actually made by
LCSI (see above) but it comes quite inexpensively bundled with the
reproducible workbook/textbook. I highly recommend the entire package. A
real bargain! (The programs are called Investigations In Number, Data and
Space(R) and Connected Mathematics. For questions about these
programs, please call the special toll-free number of 1-800-417-2321.)
