To use Skillmatics Space Explorers, start by reading the welcome letter to understand the overall idea of the kit. Then, pick an activity from the 20 repeatable ones on the double - sided activity mats. Use the Skilly Billy pens to complete the activities. After you're done, you can use the duster cloth to wipe the mats clean and do the activities again. When using the pens, make sure not to press too hard to avoid damaging the tips. Keep the kit in a dry place to prevent the mats from getting wet. If the pens run out of ink, it might be time to replace them. Once your child finishes an activity, you can give them the achievement certificate to make them feel proud.
