Lesson details
Key learning points
- Brackets where an expression is multiplied by a term can be expanded.
- Like terms can then be collected so the equation is in a form that can be solved.
- Multiple identical expressions can be collected together to simplify an equation.
Keywords
Equation - An equation is used to show two expressions that are equal to each other.
Common misconception
That there is only one way to solve any given equation.
In maths we will often see multiple ways to solve the same one problem. To be able to use multiple methods is a demonstration of fluency.
