### Poly Plug Pattern

##### Stage: 1 Challenge Level:

Create a pattern on the left-hand grid. How could you extend your pattern on the right-hand grid?

### Growing Rectangles

##### Stage: 3 Challenge Level:

What happens to the area and volume of 2D and 3D shapes when you enlarge them?

### Who Is the Fairest of Them All?

##### Stage: 3 Challenge Level:

Explore the effect of combining enlargements.

### Transformation Game

##### Stage: 3 Challenge Level:

Why not challenge a friend to play this transformation game?

### Squirty

##### Stage: 4 Challenge Level:

Using a ruler, pencil and compasses only, it is possible to construct a square inside any triangle so that all four vertices touch the sides of the triangle.

### Hex

##### Stage: 3 Challenge Level:

Explain how the thirteen pieces making up the regular hexagon shown in the diagram can be re-assembled to form three smaller regular hexagons congruent to each other.

##### Stage: 5 Challenge Level:

A circle is inscribed in an equilateral triangle. Smaller circles touch it and the sides of the triangle, the process continuing indefinitely. What is the sum of the areas of all the circles?

### Similar Rectangles

##### Stage: 4 Challenge Level:

Can you find the missing length?

### Fit for Photocopying

##### Stage: 4 Challenge Level:

Photocopiers can reduce from A3 to A4 without distorting the image. Explore the relationships between different paper sizes that make this possible.

### L-triominoes

##### Stage: 4 Challenge Level:

L triominoes can fit together to make larger versions of themselves. Is every size possible to make in this way?

### Twizzle Arithmetic

##### Stage: 4 Challenge Level:

Arrow arithmetic, but with a twist.

### Arrow Arithmetic 3

##### Stage: 4 Challenge Level:

How can you use twizzles to multiply and divide?

### Scaling Clowns

##### Stage: 1 Challenge Level:

These five clowns work in pairs. What is the same and what is different about each pair's faces?

### Arrow Arithmetic 2

##### Stage: 4 Challenge Level:

Introduces the idea of a twizzle to represent number and asks how one can use this representation to add and subtract geometrically.

### Arrow Arithmetic 1

##### Stage: 4 Challenge Level:

The first part of an investigation into how to represent numbers using geometric transformations that ultimately leads us to discover numbers not on the number line.

### Plex

##### Stage: 2, 3 and 4 Challenge Level:

Plex lets you specify a mapping between points and their images. Then you can draw and see the transformed image.

### Scale Draw

##### Stage: 1 Challenge Level:

Use the grids to draw pictures to different scales.

### Arrh!

##### Stage: 4 Challenge Level:

Triangle ABC is equilateral. D, the midpoint of BC, is the centre of the semi-circle whose radius is R which touches AB and AC, as well as a smaller circle with radius r which also touches AB and AC. . . .

### Matter of Scale

##### Stage: 4 Challenge Level:

Prove Pythagoras' Theorem using enlargements and scale factors.
