I can use a letter to represent a generalised number and form a linear equation from a context.
I can use a letter to represent a generalised number and form a linear equation from a context.
Equation - An equation is used to show 2 expressions that are equal to each other.
Interior angle - An interior angle is an angle formed inside a polygon by two of its edges.
Vertically opposite angles - Vertically opposite angles are pairs of opposite angles formed when two lines intersect at a point. They are equal.
When forming expressions brackets can be missed out or incorrectly used.
Review priority of operations. Testing algebraic manipulations with numerical values can be useful when pupils are unsure if things are equivalent. E.g. the difference between 2(x + 4) and 2x + 4 can be shown with 2(5 + 4) and 2(5) + 4
