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.
Imagine the central square in a big city and its paved with large square tiles. It may be rectangular rather than square! You are going to go straight from one corner, diagonally across to the other corner. You may be walking, cycling, skate boarding or using roller blades. Which ever way you travel you will need to go absolutely straight from corner to corner.
You see in the picture above showing a very, very small example (a $4$ by $3$ rectangle). The blue line of travel goes through six of the square tiles. Maybe there are other small rectangles other than this one that crosses $6$ tiles.
Your challenge is to find what different sizes of rectangles would mean you travelled across $10$ tiles.
Your extra challenge is to find a set of answers for $12$ tiles being crossed.
Can you find a generalization/pattern/system from the ones you've done that would enable you to find solutions more easy to other numbers of tiles being crossed.
