Teen & Ten 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).
