Mango math kits (not associated with the Mango language database) are available at the back of the Kids’ Library Desk for customers to take as desired while supplies last. For developing proficiency in a fun way, they include standalone game-like activities within each packet. They cover skill levels from kindergarten through pre-algebra. Boxes at the desk are labeled to show the grade level for which the concept is intended. Customers can self serve. These are first come first serve and while supplies last. We will not order more. They are flying out of here quickly. If you get questions about them, know that they are simply giveaway items and not something we will regularly stock or something that needs to be checked out/returned.
