Class Set Montessori Calculation Frame, 4-rows, 10 pcs., in stacking box "Montessori Premium"

This abacus in Montessori colours allows beginners in maths to calculate numbers into the thousands. The abacus can be used for addition, subtraction and multiplication .

Each row is assigned a certain value and colour. 1st row = 1s (green), 2nd row = 10s (blue), 3rd row = 100s (red) and 4th row = 1000s (green). The corresponding values are marked on the side for clarity. By moving the beads for the respective value, addition tasks such as 2,365 + 1,562 can be easily solved by beginner mathematicians without the need for any other tools.

The standard Montessori colours allow other teaching material to be combined if desired such as a token game.

The frame has a slight incline so that it is easy to see and operate in front of the pupils. Even when it is placed flat on the table in front of the pupils, the slight slant provides an optimal overview. In addition, the teacher's viewis not restricted!

The abacus frame is made from sustainable and environmentally friendly RE-Wood®. The extra-large beads make it easier for little mathematicians to use and feel pleasant to the touch.

The class set is comprised of 10 Montessori abacus, 4 digits, which can be easily stored in the plastic box supplied.
