Sounds Great!

We have two animals in this activitiy - a donkey and an owl - and what a noise they can make!
You have lots of each animal, and the idea is to drag them onto the wheel. As they go round on the wheel, they each make their own sound.
Place two or three animals on the wheel and have a listen.
You can mix them - two owls and one donkey, one donkey and one owl, or you might like to stick to all owls or all donkeys.
What is the difference between the sound of the largest donkey and the smallest donkey?
What is the difference between the sounds of the different sized owls?

You can make the wheel go round at three different speeds. Use the controls to choose slow (1), normal (2) or fast (3).
You can also decide how many times the wheel will turn (up to 10 times).
Have a go.
See what you notice and talk to others about it - please tell us what you find out.

When the wheel has stopped, I want to have heard two owl "twittwoos" and four donkey "eeyores". How could I do that?
Can I put animals on the wheel so that I hear owl, donkey, owl, donkey, owl, donkey ...? Explain your answer.

The interactivity in this problem has lots of scope for use to investigate different topics of mathematics.The questions here focus on sequences and could be related to mutliples, depending on the experience of the children you are working with. The final challenges about hearing a certain number of owls and donkeys can be opened up or narrowed down as appropriate.

After exploring what things are possible, children can also try systematically to discover different combinations of sounds the wheel can produce. Younger pupils might use the big donkey as the same as the smaller ones but others will like to see it as six different possible sounds.
