An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.
Place the 16 different combinations of cup/saucer in this 4 by 4
arrangement so that no row or column contains more than one cup or
saucer of the same colour.
EWWNP means Exploring Wild and Wonderful Number Patterns Created by Yourself! Investigate what happens if we create number patterns using some simple rules.
Brenda is walking round an irregular hexagon (a shape with six straight sides). She starts off part of the way along one of the sides.
At each vertex (corner) she turns.
How much does she turn in total when she has walked all the way round?
Use this example to prove that the sum of the external angles of any hexagon is $360$ degrees.
The external angle is found by extending the side and measuring the angle between the extended line and the next side.
