Description

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 by 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.

Included in this resource:

Addition with decimals up to thousandths

Subtraction using inverse operation

Ordering decimals

CCSS5.NBT.A.3

Read, write, and compare decimals to thousandths.

CCSS5.NBT.A.3b

Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

CCSS6.NS.B.3

Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.

CCSSMP1

Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Older students might, depending on the context of the problem, transform algebraic expressions or change the viewing window on their graphing calculator to get the information they need. Mathematically proficient students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends. Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, "Does this make sense?" They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.
