Guessing the size of an angle is harder than it seems. For this game, you need a set of blank flashcards per team, a ruler, a permanent black marker, paper and a protractor for each team. Prepare sets of identical flashcards, drawing a variety of angles, in a variety of sizes. (Just because the drawn angle has longer arms does not mean the angle is bigger.) Divide the class into teams. Give the first student in each team matching flashcards, placed upside down on their desks. When you tell them to start, they should turn the card faceup, briefly study the angle and write their guess on paper. When you call "time," the players should hold up their answers. The second player on each team will measure the angle on the flashcard with a protractor, write his answer on paper and hold it up. Tell the students the correct answer and award points based on how close the guess and measurement are to the actual answer.
This protractor game reinforces the names of different types of angles. You need a protractor for each team, a set of blank flashcards for each team, a ruler, a permanent black marker and paper. Prepare sets of identical flashcards, drawing a variety of angles. Include multiple examples of obtuse angles, right angles, acute angles, straight angles and reflex angles. Divide the class into teams. Place a card upside down on the desk of the first player on each team. When you tell them to start, the students should turn the cards over, measure the angle, write the name of the angle on paper and hold it up. Award points for each correct answer.
For an angle treasure hunt, you need slips of paper for clues, a protractor for each player and a treasure. Prepare a different set of clues for each team, using angles in the clues. For example, "walk across the room at a 36 degree angle," or "look for a green-colored right angle above the sink." Explain that the teams need to use their protractors to follow the clues. Divide the class into teams. Give each team its first clue, and let it follow the clues to the prize.
Have an Angle Time Day. You need 10 copies per student of a drawing of a clock face marked around the circle of the face with 360 degrees and with regular hour and minute markings, a ruler per student and a protractor per student. Tell the students to write their names on all copies of the clock paper. Tell the students that at various times throughout the day you will tell them the location of the hour hand in degrees on the clock and the location of the minute hand in degrees from the hour. They should look at their clock drawing, use the protractor and ruler to draw the hour and minute hand locations and write the time in standard form (hours and minutes). Have the students exchange papers with their neighbor. Tell the students the answer, and ask them to pass in only the papers that are correct. Award small prizes for correct answers.
