I have an object. Can you guess what it is? You can ask me up to ten questions.
Is it made of plastic? Can I eat it? Is it bigger than an orange? Is this smaller than an apple? Will I find this only at home? Does it cost more than 15 dollars? (we could have students do dollar to Euro conversions through the internet) Is this something that many students carry in their backpack? Does this object perform a function? Is it part of another object? Is this something a lady carries in her purse?
