### Consecutive Numbers

An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.

### Tea Cups

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.

### Exploring Wild & Wonderful Number Patterns

EWWNP means Exploring Wild and Wonderful Number Patterns Created by Yourself! Investigate what happens if we create number patterns using some simple rules.

# Tiling Into Slanted Rectangles

##### Stage: 2 and 3 Challenge Level:

This activity has been particularly created for the most able. (The pupils that you come across in many classrooms just once every few years.) It is seen as a possible follow on from

"Tiles in the Garden".

This activity takes "Tiles in the Garden", much further. We can keep the main ideas the same -

• Square tiles
• A corner of a tile at each corner of the rectangle
• The ability to slice a tile into parts so as to use each part

So this one used $26$ and the slope was generated by going along $1$ and up $5$.

This time let's put on a limit of using less than $100$ tiles.

What sizes of rectangles could be filled obeying the three rules?

How many tiles for each rectangle you find?

Are there any numbers of tiles between $10$ and $100$ for which there cannot be a rectangle?
