Tens Boards: International Version

Tens Boards show the numbers from ten to ninety together with unit cards that the child slides over the zeros. Cover the zero of 10 with a 1 and 11 appears in front of the child's eyes, so the run from eleven to nineteen and on through the decades stops being a memorised rhyme. Combined with bead bars, the boards tie the spoken number name to its written form and to the quantity behind it. The international version follows the number naming used across Europe, for children from three years.
