Everyone knows the kid games Headbanz so lets do math with it. This is an activity to do just that. The teacher will copy a set of cards for each student. The students will choose who the clue giver is and the one that will guess.
Hand the set of cards to the guesser face down.
The clue giver will give the clues. They are on the cards (not in the circle)
The guesser will guess the equation in slope intercept form.
The answer is in the square, when the students gets it correct move on to the next card.
