Secret codes are so much fun, and a great way to practice nearly any math skill. Let your class become code breakers as they investigate inverse matrices. They use TI-Nspire technology to solve systems of equations which help them crack...

There is nothing more engaging than cracking a secret code! Middle schoolers will replace letters with numbers to solve problems. This game will help them to begin to understand algebra questions by finding the value of missing numbers....

In this addition and subtraction worksheet, learners solve for problems to complete the riddle about George Washington.  Students solve 20 two digit problems of addition and subtraction with some regrouping necessary.

Did you know you can send a message using only zeroes and ones? This interactive resource presents an introduction to binary numbers. Through code cards, pupils learn to convert binary numbers to decimal numbers.

Students solve matrices by multiplication. In this algebra lesson plan, students create coded messages and relate it to solving matrices. They multiply and find the inverse of matrices.

Fifth graders examine a series of rules for deciphering a code. They create their own secret message using a code after watching video. They access a web site to practice their decoding skills.

Investigate how public key cryptography works. Scholars continue their study of one-way functions and asymmetric keys and apply this information to public key cryptography. They use an app to explore public key cryptography and its...

Learners perform operations with matrices. In this algebra lesson, students use cryptography and cryptanalysis to solve problems. They add, subtract, and multiply matrices.

Students explore the lives of spies. In this secret government agencies lesson, students visit the Imperial War Museum and the Essex Secret Bunker online or in person to discover details about Britain's spies and secret bunker.

Math wizards learn the five-step plan to solve math word problems. They investigate the five-step process for solving word problems, and examine the use of code words for each of the operations and solve a problem using the strategies.

Mathematicians participate in an hands-on activity to investigate the binary number system and write messages in binary code and have classmates decipher the messages. A said video on the topic does not seem to be available, but the...

Examine a coordinated geometry grid to decode the hidden message. Pupils write a coded message to their parents using letter coordinates from the grid.

Students rewrite word problems using expressions and equations. In this algebra lesson, students use the correct variable to solve and write equations. They use the TI to graph their solution.

Learners experience the geometric method of coding by actual construction and use of a rotating grille. Students use rotations and reflections to code and decode messages. Learners explore nomenclature and symmetry.

Students brainstorm and discuss the concept of cryptography, the science of secrets in today's world and then focus on a system for sending secret messages used by Julius Caesar. They make a Caesar wheel assessing encrypting and...

Students examine the role of signal corps during the Civil War and explore the technique of 'wigwag.' In this Civil War lesson, students discuss the way they communicate long distance today, they research how a civil war soldier...

Students are introduced to the concept of variables and their uses. In groups, they are given a code in which they must find the value of the missing words. To end the lesson, they find the value of words over ten letters long and their...

Second graders explore patterns with colors, shapes, and numbers by completing a fun quiz, watching a video, creating their own secret patterns/codes and completing an online patterning game.

Students try to solve codes mathematically. The use of a code needs a key. Students try to decipher a code with a mathematical key. This requires focus and higher order thinking skills like analysis.

Learners explore cryptology. They write a research paper on cryptography. Using linear equations, students invent a code and write a secret message. Learners complete cryptography puzzles.

Seventh graders, in an introductory algebra class, code and decode messages using substitution ciphers. Role-playing as mathematicians, they work in groups to decipher several messages, one of which translates to "math is awesome."
