Lesson Details
Key learning points
The coefficients of the variable(s) may not be one.
Sometimes the terms within each binomial are not in the same order.
Multiplication and addition/subtraction with negative numbers is useful here.
Common misconception
Mistakes with partial products are even more common where algebraic terms in the binomials have coefficients greater than 1. It is common to find pupils writing that the product of 2x and 3x is 5x
Reminding pupils that because multiplication is commutative the product of 2x and 3x can be thought of as 2 × 3 × x × x
Keywords
