When the girl gets to the end of the path, what turn will she make?



Left or right? Draw a ring around the correct answer.

When the girl gets to the end of the path, what turn will she make?



Left or right? Draw a ring around the correct answer.

The tortoise always looks in the direction he is walking. He travels along the green path.



How many times did he turn a quarter turn clockwise?

The tortoise always looks in the direction he is walking. He travels along the green path.



How many times did he turn a quarter turn anticlockwise?

The tortoise always looks in the direction he is walking. He travels along the green path.



How many right angle turns did he make altogether?

The tortoise always looks in the direction he is walking. He starts facing up.



Colour a different path to get the tortoise home.

- How many quarter turns clockwise?
- How many quarter turns anticlockwise?
- How many right angle turns did he make altogether?

Work with a partner.

Look around you and make a list of six angles that you can see. Try to find at least 3 right angles. Draw them.

**Let's investigate**

You have 2 sticks: 1 red and 1 blue.

Draw how you can make one right angle using sticks.

Draw how you can make two right angles using 2 sticks.

Talk to your partner. Can you make three and four right angles with 2 sticks? If you can, draw them; if you can't, write why not.

An angle is the amount of turn between two lines that meet each other.

Use your folded paper circle to draw the lines that show:

- a quarter turn clockwise
- a quarter turn anticlockwise
- a half turn clockwise
- a half turn anticlockwise
- a full turn

Each circle in the book looks like this; the arrow shows where the turn starts:

Use your folded paper circle to draw the lines that show a quarter turn clockwise, a quarter turn anticlockwise, a half turn clockwise, a half turn anticlockwise and a full turn (each turn starts from a line pointing up).



How many of your lines made a right angle at the centre of the circle?

Use your folded paper circles to help you draw the lines that show **2 right angles**.

Use your folded paper circles to help you draw the lines that show **a half turn**.

Use your folded paper circles to help you draw the lines that show **a quarter turn anticlockwise**.

**Let's investigate**

Next time you see a bike, look at the wheels. As they turn, the shape of the wheels stays the same.

Work with your partner. Look at these 2 wheels.



What is the same about them? What is different?

Draw 2 different car wheels. Write 2 things that are the same. Write 2 things that are different.

Which of these dots show the centre of the circle?



(The circles are counted from the left: 1st, 2nd, 3rd, 4th.)

Look at what your partner is wearing. Draw 2 things that show angles.

Draw where the red spot will be after:



- a quarter turn anticlockwise
- a quarter turn clockwise

How many times does each spinning toy look the same during a full turn?

This is the 1st toy:



Write the number for this toy.
