This activity helps reinforce double-checking work for mistakes. This is great practice of descriptions of a person's hair color, height, and age. It is also great practice of the verb "tener" and "ser". This game corresponds with Chapter 5B Realidades B.
Students start with 100 points. They decide whether the sentence is "Buena" or "No Buena" and then place a "bet" on their decision. If they are correct they add the bet to their total. If they are wrong they subtract the bet from the total. If the student can fix the mistake, they add 5 points to their total. At a certain number of points, I give a candy pick, this is very motivating! Enjoy!
