BEADS FOR THE TENS BOARDS WITH BOX
Work with the teen board starts from around the age of four when the child has been working with the first psycho arithmetic materials and begins to recognise the quantities associated to the numbers from 1 to 10. The specific aim of this material is to reinforce what the child has learned and proceed in the knowledge of the numbers 11 to 99. It can be used together with the alphabets, for example with the two colours alphabet (LI08) to deepen the knowledge of the number nomenclature.
