Lesson details

Key learning points

  1. Words you have used to describe numbers can also be used in algebra like factor and product.
  2. It is important to be able to use the words term and coefficient correctly.
  3. Knowing the difference between an expression, a formula, an equation and identity can help you speak mathematically.

Keywords

  • Identity - An identity is an equation that holds true for all values of the variables. The symbol ≡ is used to show two expressions form an identity.

  • Formula - A formula is a rule linking sets of physical variables in context. The plural of formula is formulae.

  • Coefficient - A numerical coefficient is a constant multiplier of the variables in a term.

  • Constant - A constant is a term that does not change; it contains no variables.

Common misconception

Pupils may think the coefficient of b in a-2b is 2 instead of -2 .

Show subtraction as addition of a negative value. This can be done with negative algebra tiles.

You may wish to get students to explore as many factor pairs of a term as they can. Highlight the need for systematic listing to show that all have been found.
