<p>An educational apparatus for developing numeracy and literacy skills comprises a learning wheel 1; capable of receiving dry wipe markings but also able to use magnetophoretic technology. The said wheel is mounted on a hand held stand and is comprised of four interchangeable plates 2, 3, 4, 5 being rotatably mounted together through a unit 6. Upon rotation of plate 4 whilst plate 2 and 5 remain stationary; indicia inscribed or otherwise disposed along the plate 3 surface is revealed through openings 9 and 11, the said openings being of any desired size and shape relative to the general size and shape of plate 3 and 4. Further rotation of the plate conceals the displayed information, challenging the user to write (on plate 3) the said information from memory. A magnetic arm 26 is arranged to rotate about the axis of the magnetic plate and erase any of the magnetic markings made by the user.</p> |
