Recording 22. Here's how to wrap a present. First, gather together all of the things you need: wrapping paper, sticky tape, scissors, some ribbon and, of course, a present.

Then, place your present on the opened wrapping paper and cut a suitable amount using the scissors.

Next, wrap the paper around the present and stick it down with sticky tape. Then, neatly fold up each of the ends of the paper and stick them down.

Finally, tie the ribbon around your present. It's now ready to present!
