# Maths KS2: Let's Have Some Order

In this clip the order of operations in calculations is introduced.

Correct order of operations ensures that mathematical expressions are unambiguous.

We see a calculation involving all four arithmetic operations, brackets and an exponent. The calculation seems complicated, but by doing one operation at a time and in the right order, we arrive at the correct answer.

The end sketch further demonstrates correct order of operations, utilising the great British traditions of manners and queuing.

This clip is from the series Kick Sum Maths.

### Teacher Notes

Students could be encouraged to explore how and when inserting brackets can change the result of a calculation.

The order of operations can serve as an ideal opportunity for revision of basic number facts and skills.

In conjunction with fractions, students could also explore when brackets are absent yet implied, for example the fraction with 5-3 as numerator and 6+4 as denominator.

### Curriculum Notes

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.
