This Tinker Tray is great for sorting objects! You can write down different ways to sort on the whiteboard such as colors or numbers and let your little one put them in the correct spots! Now it comes with peek a boo squares! This insert can also be used for addition and subtraction skills! You are purchasing: 1 Large tinker tray 10 blank peekaboo squares Optional upgrade to peek-a-boo squares with numbers 1-10 on one side. What will you come up with?!   What Makes our Lids/Inserts different? Each lid/insert will also come with different ways to change up the play of the activity and work on a larger variety of skills. These ideas will come from my years of experience as a pediatric occupational therapist. All of our boards are created with the idea of helping your child master new skills for a variety of age groups. *Lids/Inserts are not intended to replace traditional occupational therapy services but instead bring the fun to your home for all kids of all development styles!     Item is water resistant but not water proof. Lid should not be used to eat from. If splintering or cracks appear with use, discontinue use and discard.     Photo credit to @gear4littles and @CuriousLittles2
