This material consists of a square wooden board with a grid of 100 squares engraved. The first row and left hand column have the numbers 1 to 10 engraved. A set of small tiles with the results of the 81 products of the numbers 2 to 10 are placed in a wooden box without lid. The material comes complete with a plastic coated control table. All wooden parts have a UNI EN 71-3 finishing.

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 19. It can be...
When working with the tablets and counters (from the age of three years onward) the child learns the numbers 1 to 10 and the quantity of single pieces associated to the number as well as the concept of even and uneven numbers. This material can be used with the mat MA18.
Starting from around 5 years of age, when the child has already worked with the teen and ten boards, it can work with the short chains and squares. The goal is for the child to directly experience the power of the numbers in their geometric and numerical organisation.
Working with these boards enables the child to memorize the results of subtractions of small numbers by repeating the exercise. The vertical line is engraved between 9 and 10 and emphasizes a key passage.
Using this material of high esthetic quality to attract the child’s attention, from the age of around five it will be able to explore and master basic arithmetic operations by manipulating concrete objects. Moreover, by repeating the exercises, the child will progressively memorize the results of the arithmetic operations and this will be very useful for...
This material, to be used from 5 years onwards, introduces the child to the concept of fractions and work with fractions.
Starting from around 5 years of age, when the child has already worked with the teen and ten boards, it can work with the 1000 chain. By experimenting the linear breaking up of the square and then of the cube, the child gets more and more confidence with the numbers from 1 to 1000. Moreover, it is the first approach to the power of a number. A 10 bead...
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.
The specific aim of this material, used in combination with the MA27 introduction to the decimal system, is for the child to get acquainted with the decimal system. The golden beads are particularly precious because generally they have a triple value: arithmetic, geometric and algebraic. This material can be used from the age of four, when the child has...
From the age of 3 years the number rods get the child acquainted with the numbers from 1 to 10 through linked units: each rod corresponds to a number on the corresponding card (MA19), and the units are clearly shown by the sequence of blue and red segments. The child can thus control the error by counting the units. This material also introduces the child...
Working with this board, from the age of five onwards and by repeating the exercise, enables the child to memorize the results of simple divisions with results from 1 to 81.
The big bead frame is to be used after the small one (MA12). The goal is to accompany the child towards abstraction: from the analysis and operations with real quantities to those with positional numeration, according to the decimal system. Whereas the small frame allows to work with numbers up to the thousands, this one goes up to the millions.
The material is to be used together with the checkerboard (MA20) and the number stamps (MA20-A) to make multiplications with big numbers and to make a geometric analysis of the multiplication.
This material can be used from the age of 4 onwards when the child knows the the golden bar of tens, the numbers 1 to 10 and the coloured bead bars. The goal is to memorize subtractions.
This material, to be used from the age of 5 onwards, allows the child to immediately catch the concept of multiplication and division by simply handling concrete objects and also makes clear how the two operations are one the inverse of the other. By repeating the exercise, it also allows to progressively memorize the results of simple multiplications...
