Halloween Math: Add, Subtract, & Order Decimals ~ Crack the Code! is a fun and engaging way for students (grades 5-7) to get computation practice. They’ll enjoy the challenge and feedback is immediate through solving the puzzle (a quote from MacBeth) correctly.

This Crack the Code puzzle has three parts. First, students must successfully solve the addition & subtraction problems. Next, they must place their answers in order from greatest to least, thus making the alphabet a number line from A (greatest) to U (least). Finally, students find the corresponding numbers in the code and place that number’s letter in the blank.

Built-in problem-solving challenges include computation errors and ordering the decimals incorrectly. If they make a computation error, it can throw off ordering the decimals correctly and cause problems in cracking the code. Or, maybe they get all the computation correct, but they’re off in ordering the decimals. Their challenge will be finding a way to track down their errors, make their corrections and successfully Crack the Code.
