Thinking about things beginning with 'th'!

Today is THursday, and we have been THinking of THings beginning with 'th', because that's our sound of the week!

Luke brought in two types of THermometers from home. "They show if you are too hot," he said. Some of us had experience of having our temperature taken using a thermometer.

Amber brought in a THorn. "I found it at the garden centre. You have to be careful because it's sharp."

Can you THink of some THings that begin with 'th'?
