Gave my Y9s this diagram for #MathsToday. Picked a few numbers for a,b,c and then their task was to work out all the lengths and angles. Next lesson we'll cut it out and reassemble it and they'll discover that they've secretly been doing 3D trig! #UKMathsChat #ITeachMaths

Great idea and implementation! When I do it right (not always!), the new topic seems natural and like something they could figure out on their own. This seems right in that style!
