This puzzle, along with most of the other puzzles that I write, is a mental exercise in integrating, reviewing, and blending. I want to integrate more than one subject in a learning activity, cross-curricular learning as it were. All of life’s experiences are integrated activities. I want to review previous material a student (puzzle doer) has been exposed to. We get better at tasks in life by repetition. I want to blend a learning experience with as many other learning situations as I can.
