### PRODUCT DESCRIPTION

Decimals: Multiplying, Rounding to Hundredths, & Ordering ~ Crack the Code! is a fun and engaging way for students (grades 5-7) to get computation practice with decimals. They’ll enjoy the challenge and feedback is immediate through solving the puzzles (quotes from The Phantom Tollbooth) correctly.

These Crack the Code puzzles have four steps. First, students must successfully multiply and then round their answers to hundredths. Next, they must place their answers in order from greatest to least, thus making the alphabet a number line from A to Z. (There are two puzzles in this resource, one ordering from greatest to least, the second puzzle ordering from least to greatest.) 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, rounding inaccurately, 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.

Included in this resource:

♦ Multiplication of decimals/whole numbers
♦ Rounding to nearest hundredth
♦ Ordering decimals
♦ Teaching Notes and Answer Key
♦ 20 problems in each puzzle, student copies in BW
♦ Aligns with CCSS
