  • Thanks very much for this one. We developed it into a whole lesson and I borrowed some hats from the drama department to add to the fun!
  • Class 5G, Lakeside Community Primary School
  • We all had a go at the combinations but didn't get as far as 1024! We enjoy these starters - keep them coming =).
  • Roslina Ahmad, Malaysia
  • This is great! I can use this in my math class.
  • 8MS, Hirst Park Middle School, Ashington
  • Our year 8 class needed a bit of structure to get the solution, we worked out for 4 hats on 1 day, 2 days, 3 days, then managed to find a rule and get the answer.
