Crack the Code: Common Factors Encryption Worksheet | Differentiated Puzzle
Can your students break the code? In this engaging activity, students become "Code Breakers." They must find the Common Factors of specific number pairs to unlock a cipher and reveal a hidden secret message (a fun joke/riddle). BUILT-IN DIFFERENTIATION: We know every classroom has mixed abilities. This resource includes two versionsof the same puzzle: Level A (Scaffolded): Includes "Hint" columns (e.g., tells students how many factors to look for) to support struggling learners.Level B (Challe

Binary Math
This handout is used to help the students convert Binary Code into Base 2 numbers. 0's mean off, 1's mean on. Instead of using Base 10, teach the students base 2, convert, and perform the functions. This is the final product after a study of Binary Code and Base 2.
There are quite a few lessons online with Binary and Base 2, but I created this to go with what I found online.

Students take on roles to act out loop execution: Counter — reads the loop header, tracks the counter (i, k, etc.), and signals laps. Runner — physically runs laps (or steps) and announces variable updates. Variable Tracker — records variable changes without seeing the runner. (Optional) Recorder — writes down final values for submission. The structure helps students internalize loop iteration, in
