Sorry it took so long  hopefully useful to you next time, but I have now posted the solutions

Corrected! Thank you

Hi! Could we have it in pdf or ppt file? thank you

Wow, well done Ewa  That is quite ironic given the point of the exercise  'what difference does an extra zero make here and there' Anyway, it should indeed be 27000000 but it seems that the calculation was done as though I did have 27000000...

Hi there! I love this activity and used it for the second time this year to begin my Maths Studies course. It clearly made an impression on my students who admitted to being shocked by the final estimate. However  we did spot an error in...

Thanks Jim!

Hi Jim, I can't seem to find the video referred to here. Number Rights. Can you tell me where to find it? Thanks, Cindy

Great activity! I used the worksheet (Meeting functions) with my class  and got them to place the relevant inputs, function and outputs in a table on an A3 poster. The only comment I would make is that the output {4,3,1} should be {1,3,4}...

Are the summary slides somewhere that I can download them so I can tweak them for my class?
