Thinkamajigs Ten and Teen Boards

The Teen and Ten Boards set includes two boxes, each containing two counting boards with slots for the included number cards. The boards themselves measure 39 x 14 x 2 cm and the number cards are 7 cm square. Each storage box measures 43 x 17 x 6 cm. This exercise works best when used together with the Bead Bars for Teen Boards and the Bead Bars for Ten Boards (both sold separately).
