This kit contains nine manuals regarding use of the ArithmaTHINK kit, as well as an "arithmetic board", many puzzle pieces for the board, a notepad to keep track of results, and several wheels with mathematical equations. All of these are used in conjunction to help a parent home-school their child in mathematics. This manuals are all copyrighted in 1968, although the kit was produced in 1969.
