This is one of the best questions on error intervals. Really separates out students who answer procedurally and those who understand. It's a great question.

My adorable Year 10s finished their #GCSEstatistics today. They seemed very happy. They made me this fabulous card. I will miss teaching them.

The Thick of it. Best thing ever on TV.

Bought a physical paper for the first time in years. The cashier in the shop said "Do you mind?" and thumped the picture of Trump. The person behind me in the queue muttered his approval. In village England this is akin to an uprising.

Finished this GCSE stats revision mat for our Easter revision sessions. Happy to share if anyone wants it. #mathstoday

Today, as well as being St Patrick's day, is the commemoration of the death of Captain Oates - I am just going out now and I may be some time. "A brave man and an English gentleman."

Spent the day in Ely visiting the cathedral. Completely blown away by it. How on earth did they build it?

If Greek gods were on Love Island

In #mathstoday promised to show my year 12s this bad boy. Literally no other teacher in the department had any idea what it was. This was what I had to use when I started school.

I wrote today to my MP, James Cleverly, about the cuts to the AMSP. I am not optimistic that much can be done, but you never know. If we could get every maths teacher to write then maybe they might think again. Maybe. #ALevelMaths

This is the report that we give students after every major assessment. As mentioned, Ss enter test scores via Forms, and an Excel macro spits these out. They are perfect revision guides. Also good to give parents.

This was the book on leadership we were given. A lot of it is relevant to civilian life (some of it is a bit Colonel Blimp-ish it has to be said).
