Next, you need to think carefully about the SIZE of the Date: part you overlap. This gives people information too!

Look at the first diagram. Then, draw and shade in carefully inside the Venn circles using the patterns in the key boxes to show:

(a)

My key

(a) Most wild animals have fur. (b) About half of all pet animals have fur.

My key

(b) All lemons have pips.

r o e t s Bo r e p ok u S

(a) Because most of the circle is INSIDE the ‘Animals with fur’ part, this means that MOST wild animals have fur.

(c) Most oranges have pips and a few don’t.

This time, think hard how to show that nearly all oranges have pips and that only a few types don’t.

‘WOW – thanks – the PERFECT GIFT!’

Here’s your chance to practise using criteria in real life.

You need to make up criteria for people to use before they choose you a present. Showing them this list might even help them to recognise that there are other alternatives too!

r o e t s Bo r e p ok u S

1. Discuss the following questions before you make up your criteria:

•

•

•

•

•

2.

Is anyone disturbed easily by noise in your family? How can some gifts avoid this?

Teac he r

•

Some gifts are boring after 2 or 3 days – why is this?

What makes you treasure a gift for a long time?

Some gifts delight you even though they weren’t expensive – what is it you like about them?

Do you like doing things on your own or with others?
