SSDD Problems

By | 16th March 2018

I’ve been using Mr Barton’s SSDD Problems with my year 11 class. I think they’re really good. They do a really good job of making students pick out what they need to do.

Here’s a great one.

This is great because it makes pupils read the question. It was fantastic for revision because we got to discuss 4 topics in one lesson.

There are loads of great SSDD problems. I recommend Socks in a drawer, this nice circles one and this difficult formula one.

Some are less good, though. This one for instance:

I made this one. I’m not sure it’s a proper SSDD. It’s just 4 different questions based on the same image. Not sure it quite fits the SSDD criteria. I’m also not quite sure I can put my finger on exactly what the SSDD criteria is.

As ever, thoughts appreciated.
