The game Ninja Saviors (Warriors) is based on an old SNES beat-em up title of the same name (which was later re-released on the Switch and PS4). I came up with the idea after teaching the students the US/UK standards of measurement (in a bit of a boring manner). To make up for the staleness, I came up with the elimination style card game.
After learning/understanding the grammar points, each row of students will take an individual card from a deck. Each card will have a random character. To save time and move along quickly, have the deck of cards face down and instruct the students to not try to look at what they received or choose a card.
Both JTE and AET should have A3 version of a character from the deck to demonstrate with. Each card will have the name of the character and four parameters (height, weight, price and attack power).
Two players can engage each other by choosing who goes first, or playing janken to get the conversation going. After choosing, the conversation should start off with a simple introduction...
A: "My character is ( )."
The second player will do the same. Both players must keep their characters' parameters a secret. Student "A" will choose one parameter and announce it. For example...
A: " (His / Her / It's / Their) is 5 feet and 6 inches tall."
B: " My character is 7 feet tall."
The character with the greatest number is the winner. The loser must surrender their card to the winner.
If you have enough cards, then the loser can request a card from you. Speaking of which, if you have the time and energy to create a double batch of cards, you can make your own card shop at the front of the classroom and have the students request cards from you using "I would like (a card / this card) please." Make sure the cards are face down so the students will not spend too much time trying to choose the best character.
A little more information: I got my information by using ChatGPT to create each parameter. If you would like, you can make your own changes to better suit your lesson/activity.
