Teen boards

The Teen boards are made entirely of birch wood. The game consists of two wooden boards divided into ten equal spaces: on one board the number ten is printed vertically and shown five times; on the other, four times. Each space has a groove in which the number cards representing the symbols of the units from one to nine can be inserted. The game makes it easy to understand the writing of numbers from eleven to nineteen and, with the help of the pearl sticks, to learn the formation of numbers, their names and the correspondence of symbols and quantities. The pearl sticks, contained in a wooden box, are nine golden ones of ten and nine coloured ones corresponding to units one to nine. Covering the zero of the first ten, inserting the one card, you get eleven, next to the number you then place a ten stick and a pearl.
