Three different teaching apparatus are disclosed. In a first embodiment, the apparatus comprises a master strip 10 having a plurality of equally sized sections, and a plurality of operation strips 14, the operations strips having lengths which correspond to an integer number of the equally sized sections of the master strip. The operation strips are arranged in use to be placed adjacent the master strip in order to teach mathematical functions. The sections of the master strip may be numbered e.g. from zero, and a stop portion 13 may be provided below the first section. In a second embodiment (Figs 5, 6) the teaching apparatus comprises a first page and a second underlying page. The first page contains one or more questions and adjacent to each question a cut away portion 54 in which the answer is written. The second page is arranged to receive the answers written at the cutaway portion and contains the questions and their answers so that the given answer can be checked. In a third embodiment (Figs 7, 8) the teaching apparatus comprises a sheet of material having an indented outline of various letters, such that the apparatus can receive the end of a writing implement and thereby teach the writing of letters. |
