Video summary
This clip introduces prime numbers, composite numbers and factors.
We state that the number "1" is neither prime nor composite. The idea of factor pairs is introduced.
We look at how to decide whether a natural number is prime or composite by looking for proper factors.
The importance of being methodical is emphasised.
The clip ends with a square roots sketch illustrating the relationship between square numbers and their square roots.
This clip is from the series Kick Sum Maths.
Teacher Notes
This clip can form an introduction to prime and composite numbers, and lead to discussion of ways to speed up identification of primes/composites, for example, using divisibility tests.
The sketch at the end of the clip can serve as a discussion starter about square numbers and square roots.
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.
