Can you decipher the common phrase or fact that has been put into code? For example, 26 L of the A stands for 26 letters of the alphabet and 90 D in a RA represents 90 degrees in a right angle. Your students will be challenged and have fun trying to figure out each code's meaning. Some math and science knowledge is needed. There are two sets of puzzles and one template for students to make their own codes. Game 1 is slightly easier than Game 2. Keys are included.
