Using matrix multiplication and inverse matrices, students are trying to uncode a coded message. Students encrypt simple messages using 2 x 2 matrices.

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

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

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

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...

Young scholars relate Cryptography to the solving of simultaneous linear equations in matrix notation. They explore various methods of encrypting and decrypting codes. Pupils discuss and solve simultaneous linear equations.

Students explore the concept of code theory. In this code theory lesson plan, students discuss noise, error correction, Hamming distance, parity check matrices, and cyclic codes. Students develop these concepts through practice and...

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

Students explore the history of cryptography. They assess function notation and transformation, matrix operations, and the fundamentals of modular arithmetic. Using graphing calculators, students develop their own encryption schemes.

It's electric! Young anatomists use Virtual Neurons software to build, control, and analyze complex nerve circuits within the body. Colorful and packed with content, class members enjoy interacting with the nervous system...

Don't lose your marbles — you'll need them for a lesson on neurotransmission. Young scholars build a neurotransmission model using marbles, beads, rubber bands, string, and other elements. After studying specific neurotransmitters,...

Addiction is a big deal! Playing a game of cards helps learners understand the concept of addiction. Through their analysis, they examine the potential for addiction and how it varies for each individual.

Young scholars 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.

Based off of the hit television show NUMB3RS, this lesson uses matrices (inverse and multiplication) to decode messages hidden within digital pictures -- a process known as steganography. This method of hidden communication is known to...
