Product description: The Algebraic Binomial Cube consists of a wooden ‘cube like’ box that has two of its sides hinged allowing them to open flat so as to see the hidden cubes. The box holds 8 wooden cubes and rectangular prisms painted in red, blue and black. The Binomial Cube is a concrete representation of the algebraic formula (a + b)3 = a3+ 3a2b + 3 ab2 + b3 . The factors of the equation are represented by the cubes and the prisms. The top of the wooden box shows the pattern in a flat dimension.
Size: 9.5cm x 9.5cm x 8.5cm / 3.74" x 3.74" x 3.34"
Not suitable for children under 3 (small parts)
Educational and Fun go hand in hand: The Algebraic Binomial Cube forms part of the Sensorial Area that Dr. Montessori classified as vital for the child’s development of his senses and appreciation of the world that surrounds him. This educational toy can be used as a tridimensional puzzle for the younger children to play with and with older ones it can be employed to create different challenges in its assembly. The Binomial Cube can be put together in different ways such as in storeys or by color, either inside the box or outside of it. The wooden top of the box shows the image of the correct assembly of the Binomial Cube. It is a visual aid to help the child play with this wooden toy so he is not frustrated if he cannot put it together right away. On the other hand, if the Binomial Cube is not put together correctly inside the box, it will not be able to be closed properly so the child immediately becomes his own Control of Error. The use of this Montessori material will allow the child to observe concretely where the formula comes from and get a better understanding of the formula as he grows older.
Why buy this item: The Algebraic Binomial Cube is an excellent material to be presented to any child over 3 years old because it appeals to their innate curiosity to build puzzles, especially if it is tridimensional. The child has fun assembling cubes and prisms together to form a bigger cube. And the color in each one of them guides the child to unite them correctly to form the final Binomial Cube. This educational toy introduces the child into algebra and prepares him for future mathematics.
