This puzzle, along with most of the other puzzles that I write, is an attempt to integrate, review, and blend. I want to integrate more than one subject in a learning activity. 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. Few life experiences are isolated happenings.
This puzzle blends algebra and geometry in that triangles with unknown angles and sides are given in terms of variables, and the student must add them up, set them equal to 180 (or the perimeter) , and solve. In the process, they'll learn about Mallard ducks.
There IS a Prelude that accompanies the puzzle which reviews/explains the process for the student /puzzle-doer who needs some take home assistance or review. It does NOT show how to solve the equations, only the set up required. This is a puzzle from my book Fun with Savannah (for the well-rounded puzzler who wants to know more.)
