These four ingenious sets all include a tablet & a magnetic pen. Use the directional arrows & trace each letter or number with the magnetic stylus for a sensory-driven reinforced lesson. As you move across the tablet, the pen lifts the magnetic balls into position enabling you to see the results of your work. These superb resources will help to improve the writing & drawing skills of children. If you make a mistake simply use your finger to erase the error & build your confidence as you go.
