These two group activities use mathematical reasoning - one is
numerical, one geometric.
An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.
EWWNP means Exploring Wild and Wonderful Number Patterns Created by Yourself! Investigate what happens if we create number patterns using some simple rules.
Michael and Robert from Necton Middle School
in Norfolk sent the following solution, where the sides all add up
Simone from Stroud Green Primary School sent
us another solution where the sides all add up to 17.
In fact, there are lots more solutions. Here's
a list of them (including the two shown above). Each group of four
numbers makes up a side of the triangle. Of course, within a side
you can switch round numbers that aren't on a corner, but that
doesn't really give any new solutions.
