=====================
In this clip, the concept of 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 BBC series Kick Sum Maths. The best fun anyone can have learning maths! It’s a mixed-media mash-up maths sketch show delivering KS2 maths.
Each subject flows seamlessly from one teaching point to the next, using animation, puppetry, live action and visual effects to bring maths to life in a whole new way. It has an anarchic, dangerous look and feel, captivating children from the outset and engaging them all the way through the clearly explained maths.
Topics covered include prime numbers, finding factor pairs, shapes and angles, perimeter and area, scale and coordinates, pie charts, fractions and decimals, percentages, the order of operations and an introduction to algebra.

Teaching Maths?
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.
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.
