Foreign Language
Divide your 12th grade class into groups to work cooperatively. For foreign language classes, show each team a picture or photograph. Have the students write down one letter of the word it represents in the foreign language, without revealing their letters to their teammates. One student writes down the first letter, the next the second, and so on until the word is spelled out. At the end, the students reveal their words after a certain time limit has expired. Award one point to the team with the correct spelling of the word and then continue the game with new pictures.
Scavenger Hunt
Arrange a scavenger hunt for your 12th graders. For a math scavenger hunt, have the students find geometric shapes such as cones, rectangles and parallel lines. For example, a traffic cone would serve as an example of a cone, and railroad tracks would serve as an example of parallel lines. Provide the students with lists of the geometric terms and digital cameras so that they can take photographs of the objects that they find. Afterward, have the students explain how the objects match the geometric terms.
Jeopardy
Come up with questions and answers, Jeopardy-style, for subjects such as math, history or English. Create a game board on the computer or draw a game board on your chalkboard or whiteboard. The game board should include the same dollar values as the show Jeopardy, with the subject matter divided into columns at the top for different categories. Have the students divide into teams and then play Jeopardy by choosing a column and a dollar value. Show them the Jeopardy answer that fits their choice and then award them the related points if they guess the correct question. Hide a Daily Double clue in your game board and have a Final Jeopardy answer ready for the end of the game.
Road Rally
Divide your students into groups that can each fit into a car. Mark out a route outfitted with clue stations along it. At the clue stations, the students must solve a clue to discover the location of the next station. The clues could relate to math, geology or any other subject matter. Ask for parent volunteers to drive the students in cars, or create a footpath version of this game that takes place in the woods or in a large building. The team that arrives at the final location first wins the game.
