Clock Arithmetic and Cryptography	Lesson: Introduces students to modular (clock) arithmetic and how modular arithmetic can be used to encode messages using simple shift, multiple and affine ciphers.
Clock Arithmetic	Activity: Work with various types of clocks in order to learn about modular arithmetic operations. Parameters: Number of hours on the clock.
Elapsed Time	Activity: Practice finding elapsed time given a starting time and an ending time. Elapsed Time is one of the Interactivate assessment explorers.
Function Machine	Activity: Students investigate very simple functions by trying to guess the algebraic form from inputs and outputs. Function Machine is one of the Interactivate assessment explorers.
Number Cruncher	Activity: Similar to the original "Function Machine" but lists input and output in a table and will not let the user attempt to guess the rule on without at least having two data points.
Order of Operations Four	Activity: A game like Fraction Four but instead of fraction questions the player must answer order of operations questions (addition / subtraction, multiplication / division, exponents, and parentheses) to earn a piece to place on the board. Parameters: time limit, difficulty level, types of questions. Order of Operations Four is one of the Interactivate assessment games.
Tables and Chairs	Activity: Explore rectangular and straight-line arrangements of tables, calculating the number of chairs needed to surround different arrangements thereby exploring perimeter concepts. Tables and Chairs is one of the Interactivate assessment explorers.
