Maths KS2: X Marks The Thought
In this clip the basic principles of algebra are explained and explored.
We see an equation of the kind that students will be expected to solve, where an icon stands for an unknown.
We replace the icon with “x” and demonstrate solving simple equations by using inverse operations.
We also see examples of simplifying an expression by collecting like terms.
This clip is from the series Kick Sum Maths.
Aside from introducing Algebra, this clip contains literacy elements such as the etymology of the word “algebra”, “like terms”, “inverse”, and “drawing a squidgy x”.
Students could explore the etymology of other mathematical words and phrases and also compare and contrast the mathematical meanings of some words to their everyday usage.
These clips could be used for teaching Maths at KS2 or at a beginner level in England, Wales and Northern Ireland and 1st and 2nd Level in Scotland.
