To use this Playfoam Sand Sensory Set, simply take out the Playfoam Sand from the packs. You can start sculpting it using the scissor mold, stampers, roller/scooper, and cutter. Encourage kids to count the shapes they create to develop number recognition. It's a great addition to sensory bins, so you can mix it with other items. When you're done playing, store the Playfoam Sand in a sealed container to keep it fresh. Make sure to keep small parts away from very young children to avoid choking hazards. Also, clean the tools with mild soap and water after each use to keep them in good condition.
