Was thinking of giving this to Year 10 soon to sum up what they have seen in trigonometry.
Goal: Find as many ways as possible to solve.
One exact solution needed.
Could be turned into a more or less rigorous exercise with bounds as well.

Hello #MathsToday, would someone know a good place to find quite challenging questions for Year 11s, and which are as remote as possible from a GCSE style question (but workable with what a year 11 should know in theory)?

Curious...i'd be interested in honest thoughts of uk teachers about how Geometry is taught in KS3/KS4 and its curriculum in those years?

In #MathsToday (actually last year, first year teaching), we trained with Y10 on quadratic substitution with the challenge to be the first to find a non prime number generated by special polynomials (mathworld.wolfram.com/Prime-Genera...). Drawback is not using negative integer values to substitute.
Prime-Generating Polynomial -- from Wolfram MathWorld
Legendre showed that there is no rational algebraic function which always gives primes. In 1752, Goldbach showed that no polynomial with integer coefficients can give a prime for all integer values (N...

Curious. How many of your students could do the following without using "angles in polygons" type of reasoning?
"On the plane, a quadrilateral has three right angles. Prove that the last angle is also 90°."

Challenging students to come up with some convoluted equalities after I showed them Grid Algebra (by Dave Hewitt), I wrote on the board what was dictated to me by a Year 7 student. Sorry for the squished 14. #MathsToday
