Sometimes, there is a better way. Scholars develop Pascal's triangle as a method to arrive at the coefficients of binomial expansions as an easier method to expand binomials. The learners connect the formula for binomial coefficients to Pascal's triangle in the fourth lesson plan in a series of 23 in a Precalculus module. Class members realize Pascal's triangle or calculating binomial coefficients are more efficient than the tedious process of expanding a binomial by hand.
