School Swap: The Class Divide - Netflix

This two-part documentary features a comprehensive headteacher and three pupils swapping with their private counterparts to find out if public schools give you a first-class advantage, and whether a state education really means second-rate.

In a unique experiment Jo Ward, the head of 700-pupil state secondary Bemrose School in Derby, takes three of her pupils - Brett, Nazh and Qasim – to meet Mark Mortimer, who runs 400-pupil Warminster School, a private boarding establishment, and three of his own pupils - Xander, Katy and Jon.

With GCSE A to C grade pass rates of under 50 per cent and an admissions policy that means more than half of new students don't speak English as their first language, Bemrose could be said to be a typical urban comprehensive. And with annual boarding fees of more than £27,000 and a dozen tennis courts, Warminster fits the perception of many fee-paying independent schools.

This programme provides a close insight into the perceived educational gulf between the two schools, the attitudes of the students and their teachers towards each other, and asks whether a private education is a ticket to a top job later in life.

School Swap: The Class Divide - Trachtenberg system - Netflix

The Trachtenberg system is a system of rapid mental calculation. The system consists of a number of readily memorized operations that allow one to perform arithmetic computations very quickly. It was developed by the Russian Jewish engineer Jakow Trachtenberg in order to keep his mind occupied while being held in a Nazi concentration camp. The rest of this article presents some methods devised by Trachtenberg. Some of the algorithms Trachtenberg developed are ones for general multiplication, division and addition. Also, the Trachtenberg system includes some specialized methods for multiplying small numbers between 5 and 13. The chapter on addition demonstrates an effective method of checking calculations that can also be applied to multiplication.

School Swap: The Class Divide - Multiplying by 9 - Netflix

Rules: Subtract the right-most digit from 10. Subtract the remaining digits from 9.

For rules 9, 8, 4, and 3 only the first digit is subtracted from 10. After that each digit is subtracted from nine instead. Example: 2,130 × 9 = 19,170 Working from right to left: (10 − 0) + 0 = 10. Write 0, carry 1. (9 − 3) + 0 + 1 (carried) = 7. Write 7. (9 − 1) + 3 = 11. Write 1, carry 1. (9 − 2) + 1 + 1 (carried) = 9. Write 9. 2 − 1 = 1. Write 1.

Add the neighbor. For the leading zero, subtract 1 from the neighbor.
