Lesson details
Key learning points
- Words you have used to describe numbers can also be used in algebra like factor and product.
- It is important to be able to use the words term and coefficient correctly.
- 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.
