This box is awesome! My 4.5yo absolutely loved it. She says she wants to do her "ocean work" (the Ocean Treasures edition of this box) while her big sisters do virtual school. The contents are carefully curated and thoughtfully put together. We do one or two of the suggested activities each day. They are age-appropriate and fun. My daughter really loved the one where I hid the starfish letter cards and she had to find them. It challenged her but was a great way to start identifying lowercase letters. Looking forward to the next box!
