Cryptology Activity
This activity allows the student to encode his or her personal message to another student in the class. They can exchange and decode the messages using inverse matrices and multiplication of matrices. Students will have to find the inverse matrix of a two by two by hand as well as multiply matrices together. This activity allows students to work both independently and with a partner. It also enables to students to think critically and creatively through the study of matrices.

Small group Skills Tracker (editable) FREE
This is a great tool to gather quick and easy data for your small groups. I like to use it for encoding and decoding. I write the group name and days I am seeing them at the top. Students name on the side and the skills I am working with them on across the top. Then I just out a check if they where able to get the skills write. This is helpful for me to capture quick and easy data for progress monitoring and to drive my instruction for the next time I see that group. Hope this is helpful.

Four Quadrant Coordinate Spelling
Letters of the alphabet are scattered around the coordinate plane. I use this for students to become familiar with the coordinate plane. I pair the students up and have then encode/decode messages from each other. I have also paired with the ELA teacher to give a spelling test. The kids loved it, but it was daunting to grade. Next time, I would offer a couple of bonus words with the coordinate spelling.

First Day Activity - Cipher
Are you looking for a fun, engaging activity for the first day of school? Your computer science or math class will be the talk of the school when you get the kids up out of their seats! Students start by encoding their name with the cipher. You collect the slips once the front side is completed. Once you have them all, have students draw a random slip and decode the name. Students will then find that student and, using the interview questions, write down their responses to the question. Once eve

Wooden cubes and spatial imagination.
Playing and working with wooden cubes is one way of developing children’s spatial imagination. If we combine it with drawing, we have a very good activity for a lesson.
Content (more than 20 problems in 8 tasks):
1. Drawing solids built up from cubes.
2. Encoding and decoding solids in two different ways.
3. Fully detailed answer key (4 pages).
It is easy to change, swap or add exercises.
Children can work, discover and draw in their own way and at their own pace with or without wooden cubes.
