This is a game that I created for my elementary school classes, but could probably be adapted for older students if the presents were awarded on the basis of grammar trivia questions instead.

Begin by introducing (if you haven't earlier in the lesson), the phrases "What do you want?" and "I want the _________ present". Then quickly go over the colours of the present cards you made (as seen in the photo).

Then split up the class into lunch groups and then establishing a rotating order in the groups, ie. Number 1 goes first, followed by Number 2, etc. Ask all Number ones to stand up. I then subdivided these groups into janken playing groups. For example, Number ones from the first set of three tables play together and Number ones from the second set of three tables play together.

Get the winners to come up to the front and demonstrate that when you say "What do you want?", the winners answer with "I want the _________ present", choosing the colour of their choice. Then give them a colour present cut-out that you made. Rotate the groups and continue this pattern until the time is up or you run out of present cards.

After each group has won some cards, I reveal what is 'inside' each colour present using cut-outs. They usually like this if you hype it up, and everyone seems to like coal being an option. Then once the contents have been revealed, tell them that each present is worth different points. The group with the highest amount of points is the winner!
