### R1 Pentominoes

**What is a pentomino?**

- A collection of five equal squares so that at least one side of each square is coincident with that of an adjacent square.

- Rotations, reflections and translations are not permitted.

- How many different arrangements can you find?

- Compare with a partner and challenge any arrangements you disagree with.

- Make notes of any points you want to raise about terminology, area / perimeter of the pentominoes you discover, challenges you faced.

- Look at the solution sheet and try some of the other challenges

### R2 Classifying shapes

### R3 – Dissecting a square

What fraction and percentage of the whole square are the other pieces?

Note your answers in a table like the one below:

Check that your answers add up to a whole unit or 100%

R 3- Dissecting a square answers

From the Standards Unit materials – session SS3

### R4 Transformations

On a copy of the sheet below, draw the image of the L-shape after the following transformations:

- Shape A: reflection in x axis
- Shape B: reflection in y axis
- Shape C: reflection in the line y = x
- Shape D: reflection in the line y = -x
- Shape E: translation of -4 units vertically
- Shape F: rotation of 90º clockwise about the origin

**Extension**

- Make up your own, more complex, transformations, record the image and label it with the transformation (for example, use a vector translation (
^{x}_{y}), use shapes which straddle the line of reflection, use a point of rotation other than the origin). - Use the blank grid below to explore with more complex shapes.

### R6 – 7 Evaluating statements about area and perimeter (no R5)

### Trigonometry

### R8 Pythagoras’ theorem – consolidation question

1. A ladder, 5m long, is resting against a wall as shown.

The base of the ladder is 1.5m from the wall.

How far up the wall does the ladder reach?

2. A plane is coming in to land. It is flying at 4000ft and is currently 2 miles south of the runway.

What is the actual distance the plane has left to fly before it lands? (1 mile = 5280 ft)

3. A square has a diagonal 14.14cm long.

What is the area of the square?
