Fermi problems are a fantastic way to teach students good problem-solving skills. They were invented by Famed Physicist Enrico Fermi to teach his students the art of solving maths problems to which we have no answer. These questions don't always have a definite answer which forces students to focus on the mathematical process rather than the 'right answer'. 

With Fermi problems, you will see students do things you could only dream they'd do in their exams:

• They will instinctively break the word problem up into smaller more manageable questions. 

• They will think about what information is missing and what they need to have to solve the problem. 

• They will demonstrate a deep understanding of the term variable! 

These 'silly' questions pique students' interest and make them curious about what the actual answer might be. The discussions will be thought-provoking, the debates will be lively but most importantly the learning will be meaningful! 

Say goodbye to dull CBAs and LC exam Section B anxiety with these fun lesson starters:

• How much money would you have if you had a stack of €2 coins that height of the spire?

• How many Helium balloons would it take to lift a house like in 'Up'?

• How many chicken fillet rolls will your tutor group eat in one year?

• How many cups of tea are drank in the staff room in a year?
