Binomial Expansion with Pascal's Triangle

A triangle provides solutions to an algebra problem. The lesson introduces Pascal's Triangle to the class. Pupils learn to fill out the rows of the triangle and use the numbers as the coefficients in binomial expansions. Using their knowledge, learners develop problems and play a matching game with other classmates.
