This material consists of two wooden boards, each divided in five horizontal parts. On each part the number 10 has been engraved, nine times with exception of the last part of the second board which remains empty. The 9 wooden tablets have the numbers 1 to 9 engraved. The teen board is used with the bead bars (MA07). The boards and tablets are placed in a wooden box with compartments and lid and all wooden parts have a UNI EN 71-3 finishing.
TENS BOARDS WITH BOX
Work with the tens boards starts from around the age of five when the child has been working with the teen board and has a good knowledge of the numbers 11 to 19. Now the numbers from 11 to 99 are introduced. It can be used together with the alphabets, for example with the two colours alphabet (LI08) to deepen the knowledge of the number nomenclature.
