This product is a zip file containing 2 pdf documents. One is the puzzle itself; the other is the solution.
While assembling this puzzle, students will practice working with imaginary numbers. This includes evaluating square roots of negative numbers, and adding, subtracting, multiplying, and dividing imaginary numbers.
How to use this activity:
Groups students into groups of 2-3 students. Give each group a copy of the puzzle pieces (3 pages). They will need to cut out the wedge-shaped pieces. Each piece contains a problem (marked by a number followed by parentheses) on one side, and an answer to a different problem on the other side. Students should work out each problem and find its answer on another piece. They then tape the two matching pieces together. The problems are numbered, simply to distinguish the problems from the answers; the problems are not in order in the completed puzzle. The puzzle forms a ring-shape when complete and contains 12 problems.
My students love doing these types of puzzles because it gives them immediate feedback as to whether they are doing the problems correctly or not. Plus, they love being able to work in groups!
