Sneaky Pete

Marshall Spooner
Greenwich Country Day School, Connecticut, USA

Eric the Sheep waiting in a long line to be shorn becomes Sneaky Pete queuing for ice cream and suddenly we are challenged to consider pedagogical questions.

Our thanks to Marshall who has, in a way, put himself on the line in offering his decisions for collegiate scrutiny. His enthusiasm for teaching and learning is infectious. We would be delighted to receive any views, opinions, comments, reactions from your discussions which could be added to this article.

This article is intended as a teaching craft talking point for your next year level, faculty or staff meeting.

  • School mathematics is about learning to work like a mathematician.
  • A mathematician's work begins with an interesting problem.
  • A problem is a problem because it has no known solution and no known pathway to solution.
  • Therefore a large part of a mathematician's time is spent working in the dark.
(In the BBC Horizon documentary Fermat's Last Theorem, mathematician Andrew Wiles describes working mathematically as like wandering around in a dark mansion of many rooms.)

Teaching mathematics in this context involves finding problems appropriate for our students, choosing teaching craft which encourages interest in them and, because classroom time constraints are real, making judgements about how much guidance to give and when. Marshall Spooner is one teacher who has made such judgements and who is happy for you to review them.


Hi, my name is Marshall Spooner, and I am a teacher in Greenwich, CT, USA at Greenwich Country Day School. I am so excited that all of your amazing tasks are now available online and downloadable as PDFs. This is awesome! Please tell me the easiest way to order the eTask library.
I have been at the school for 16 years, but just before I got here, a few of my colleagues worked with you. We still have the bags of some (but not all) of the tasks, and I love the idea that we can now have everything and be more organized! My favorite task is Eric the Sheep which we have affectionately renamed "Sneaky Pete" (see attached) which we use every year with our 8th graders (14 years old), and they love it!

Compare, contrast and discuss these two presentations of the same problem.

Remembering that both presentations of the problem are intended for pairs using concrete materials (to encourage interest), some starter questions might be:

  • What might be the pedagogical underpinning of each presentation?
  • Too many words?
  • Not enough words?
  • Why change the context of the task?
  • What part do the images play?
  • How do kids learn to ask questions if we ask all the questions for them?
  • Is a simple task card with an additional Investigation Guide a suitable alternative?
  • ...

When you have discussed with your team - perhaps even trialled both forms - read more here.
