Perimeter and Area Lessons

I have created a set of 'letters', in which the teacher will open one a day to discover what the math task is for their students. The first letter is an introduction letter that is intended to follow a lesson done as an entire class. Tuesday is a letter given by the Superhero Squad, in which they must create a superhero using regulations such as 'a perimeter of 60 squares', etc... Wednesday is the 'School of Wizards', in which it is the same ideas as the Superheroes, except they are creating a wand. Thursday are the Ninja Turtles, and they are creating a self portrait in which they must give their own measurements. The same rules apply for Friday with the Minions, and a final closing letter is given as well.
