I use this game to practice noun-adjective agreement with my Intro. to Spanish students. They love it!
Students play in pairs. I read aloud a noun--which they write down. Then I read aloud an adjective--the students have to look at their "Shark Tank" and choose the form of the adjective that correctly matches the noun for that round.
Good for vocabulary review as well--students have to remember what the different nouns and adjectives mean!
