Abstract: A calendar system comprising multiple (i.e., twelve) magnetic “month” sheets for each calendar month of the year, a magnetic “To Do List” sheet and a magnetic “Six Weeks at a Glance” sheet. Each sheet includes a header section that can variably depict the current month, year and/or day. The system further includes a plurality of magnetic “week” strips for securing to one of the sheets. Each “week” strip includes seven columns each having a day of the week imprinted adjacent thereto. Adjacent each day of the week indicia is a date space to which one of the numbered tabs is secured to appropriately label each day with the corresponding date for the particular week. A plurality of color-coded event tabs are also included for magnetically securing to one of the “week” strips positioned on a “Month” sheet or the “Six Weeks at a Glance” sheet, or directly to the “To Do List” sheet. Each time a week elapses, a “week” strip is moved from the current “Month” sheet to the “Six Weeks at a Glance Sheet.

Abstract: A method of incorporating small graphs on to pages of text or calculations by using small adhesive-backed appliques or labels which have been pre-printed with a graphical coordinate grid. These appliques eliminate the necessity of a separate piece of graph paper or the tedium of drawing or gluing a coordinate grid directly on the report or calculation page.

Abstract: In one embodiment, the musical box includes a box-like support structure and a music device disposed in the interior of the structure. A plurality of flexible continuous webs are sized to wrap around the outside of the structure. Each web has, along its outside surface, indicia representative of a particular mathematical data table, such as a multiplication table. One column of the table indicates the mathematical resultant of the remaining laterally displayed data. The resultant is disposed proximate a side of the support structure. A controllably movable strip or continuous web has a window and the window is sized to reveal one mathematical resultant. This continuous windowed web is driven by a gear and knob actuator.
