express mathematical relationships using equations

Spy Game	Lesson: Students will learn about modular arithmetic in order to decipher encrypted messages.
Graphs and Functions	Lesson: Demonstrates the connections between formulas and graphs.
Introduction to Functions	Lesson: Introduces the basic ideas needed for understanding functions.
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.

identify such properties as commutativity, associativity, and distributivity and use them to compute with whole numbers

Arithmetic Four	Activity: A game like Fraction Four but instead of fraction questions the player must answer arithmetic questions (addition, subtraction, multiplication, division) to earn a piece to place on the board. Parameters: time limit, difficulty level, types of questions. Arithmetic Four is one of the Interactivate assessment games.
Arithmetic Quiz	Activity: Similar to Arithmetic Four: Arithmetic Quiz gives the user randomized questions to answer on arithmetic with whole numbers and integers. Parameters: Level of difficulty and types of questions. Arithmetic Quiz is one of the Interactivate assessment quizzes.
Estimator Quiz	Activity: Test your estimation skills by answering questions. This quiz asks you to estimate the answer to addition, multiplication, and percentage questions. Choose difficulty level, question types, and time limit. Estimator Quiz is one of the Interactivate assessment quizzes.
Factorize	Activity: Visualize factors through building rectangular areas on a grid. First enter all the factorizations of a number, then draw each factor set as an area on the grid. Factorize is one of the Interactivate assessment explorers.

represent the idea of a variable as an unknown quantity using a letter or a symbol

Functions and the Vertical Line Test	Lesson: Introduces students to the vertical line test for graphs of functions.
Introduction to Functions	Lesson: Introduces the basic ideas needed for understanding functions.
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.
