2 + 4 + 0 + 1 = 7; 74 = 2401
2+ 3 + 4 + 2 + 5 + 6 = 22; 224 = 234256
3 + 9 + 0 + 6 + 2 + 5 = 25; 254 = 390625
6 + 1 + 4 + 6 + 5 + 6 = 28; 284 = 614656
1 + 6 + 7 + 9 + 6 + 1 + 6 = 36; 364 = 1679616

An interesting pattern where the sum of the digits of particular six digit number raised to the power of fours is equal to that 6 digit number.  Questions that might be asked with students – why does this work for these particular numbers?  Is it a coincedence and/or peculiarity?  Would this work for all six digit numbers?  How do you know?

Children as Protagonists.

This short video shows some wonderful examples of a pedagogical style that has been bubbling away in the back of my mind. Namely, engaging students in real-world problem solving. Not only will it improve their learning and engagement, but they might even come up with some good ideas.

I remember at the end of my Biotechnology degree, one of the projects was to write a mock business plan. This was done in groups, and my group was lucky enough to work on a business plan for a real company: a bioremediation start-up that some of the researchers from the uni were putting together. The fact that our project could form part of the business plan for a real company was a great feeling, and I know we did a better job because of it.
