We are going away tomorrow to visit family in Brazil and boy, it is a long journey. So I am putting together for Sofia a "anti-boredom" kit .
One of the items is this: a small tin gift box with tiny colouring pencils, a small notebook and "math" buttons, as she loves to do her little calculations (" mom, I know how much is 3 + 3!" she loves to say)
I had these buttons so I bought magnets at the dollar store, attached with hot glues and put them in the inside part of the tin.
Hope it works!
