Cryptography and Matrices

Doing cryptography with matrices is always fun! I used this as a quiz -- students had to decode the message "Once upon a time in a far away land. " and then for extra credit they get to finish the sentence. I got some really fun endings and students were excited when they decoded the message correctly. I've attached my work to show how I originally encoded the matrix. This could easily be modified to be turned into a project or another activity.

Secret Agent Matrix Equations WS

Students use matrices and equations to decode a secret message. I used it last year (and am about to use it again) and students were actually engaged and enjoyed it. They then are instructed to create their own which levels up the DOK. :) I have them work together on the WS mostly to prep them to work together to create their own. But, depending on time and differentiation needs, you can certainly have them stop after the WS or have them fly solo with it. I've used it with Algebra 2 11th gr

Morphological Awareness: Making words with prefixes, suffixes and base words

A word matrix is an excellent way to build student vocabulary. Morphological awareness means being aware of the meaningful parts (morphemes) that make up words. Having strong morphological awareness skills is correlated with stronger literacy skills. Students can systematically strip away affixes to find bound or free base words which can help with decoding and comprehension. Word walls can be created by making classroom matrices with bound and free base words and then adding prefixes and suffix
