• It would have been good if this was one of those starters where I could get a new question by using the refresh button.

[Transum: Thanks for your suggestion, there is now a button lower down this page to 'Change Numbers'. Also if you click on the link lower down the page (Transum.org/go/?to=recurring) for the related student activity you will find more recurring decimals.]
• The Best Maths Class Ever (7cd/M2), King Alfred's College
•
• Many of us found it too hard at the beginning but when we realised what we were doing, we managed to think of lots of answers.
• Miss Groves, Edinburgh
•
• Class 1B3 from Forrester High School Edinburgh were enjoying this very much. We found the answer and then we multiplied up and divided to get other results.
• J. Miley, Kingsbury School, Birmingham
•
• I agree, thank you, though ... it got them thinking!
• Jill, Knowling
•
• A very good starter although once completed you should be able to refresh it.
• Transum,
•
• Thanks for your comments. There is now a button below allowing you to generate a different recurring decimal. There is also a link to a self marking quiz related to this starter below. Did you know that a fraction in lowest terms with a prime denominator other than 2 or 5 always produces a repeating decimal?
• Mr Kennelly, 3rd Class Mayo
•
• My class found it hard to do but then we figured it out. The best one yet I think and the class loved it to :).
• Ms Polius-Curran, Basildon Upper Academy
•
• This starter has to be one of the best differentiated starters I have come across, my Foundation group enjoyed using the calculator to find the two whole numbers whilst my Higher group solved this without the calculator by using the method to convert recurring decimals to fractions.
• Mr Okungbowa, Northbury Junior School
•
• This is very good. I would like more questions like this one because they are really mind boggling and it takes a lot of working out to find correct answers.
• Sapphire Class, Gloucester
•
• We tried this in Y5/6 - the closest we could get is 1000/748 = 1.3368983
We also noticed that 52/22 = 2.363636.

I had been tutoring the wonderful Betsy for five years. When the day came for our last ever session together before the end of her Year 13, I received this beautiful book as a gift of appreciation.

This a very readable book by Ben Orlin. I'm really enjoying the humour in the writing and the drawings are great.

Ben Orlin answers maths' three big questions: Why do I need to learn this? When am I ever going to use it? Why is it so hard? The answers come in various forms-cartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that mathematics should belong to everyone.

 Teacher, do your students have access to computers?Do they have iPads or Laptops in Lessons? Whether your students each have a TabletPC, a Surface or a Mac, this activity lends itself to eLearning (Engaged Learning).
