TED-Ed Original Lessons – Can you solve the fish riddle?

One of the many TED-Ed Original Lessons places you as cargo director on the maiden voyage of the S.S. Buoyant, agreeing to transport several tanks containing the last specimens of an endangered fish species to their new aquarium. Unfortunately, the boat is battered by a fierce storm, throwing your precious cargo overboard.

Such bad luck!

This is one of a series of lesson activities that can be used in the classroom to develop mathematical thinking, as part of the Maths in Real Life series from TED. The professionally animated short videos include the opportunity to pause, allowing time to work out the challenge, before allowing you to continue revealing the answer.

It’s quite a tough mathematical challenge, probably relevant for KS3 onwards, but a great way to introduce a ‘real-world’ problem that will engage students.
