Learning Specifications
How can the model be used in class?
The binomial theorem is a fundamental theorem of algebra that is used to expand expressions of the form: (a + b) n, where n can be any natural number.
Due to the abstract nature of the expression, this 3D model can help the student to have a geometrical understanding of this formula for exponents 2 and 3.
By strengthening this knowledge, the student will be able to delve in the theory and develop formulas for any value of n, while providing an intuitive understanding of the Pascal’s triangle.
What benefits can its use have?
– Help students who have difficulties to visualize equations.
– Improve the spatial vision of the student.
– Capture the attention of those students who are not interested in mathematics.
Can it be used in other subjects?
Any subject that needs the understanding of this formula, such as physics.
