There is provided to a tilt board (1, 51, 61, 101) comprising an activity surface (3) supported by a base (5). The base comprises a front wall (7) and a rear wall (9) that extends downwardly from the activity surface by a greater distance than the front wall. The activity surface (3) comprises an activity surface surround (15) defining an aperture (17) therein and a removable activity surface insert (19) dimensioned for reception in the aperture. A plurality of interchangeable activity surface inserts (19) may be provided. The activity surface inserts (19) are also tilt adjustable relative to the remainder of the tilt board. The tilt board (1, 51, 61, 101) is provided with a circumferential flange so that the tilt board may be inserted into an aperture of a larger work surface such as a table if desired. The tilt board can be used for a range of activities, can lie flat in a larger work surface if desired, and the tilt angle can be adjusted to several angles which is highly advantageous.
