This is an interactive worksheet on evaluating limits using factoring and rationalizing.
A star chain is an engaging, self-checking worksheet that can be used in virtually any subject! First, students cut up the twelve squares (there's a problem on each one). Then, beginning at any square, students work out the problem at the bottom of the square. The answer to the problem is at the top of a different square. The students must work the problems in order so that the squares form a chain once the assignment is complete.
