Principles of Encryption.

In this activity, students develop and then compare and contrast three coding technologies based on principles of encryption.


I like this NCTM article on Inverse functions, worth trying in Algebra II GT.


Factoring Activities

Here is a Factoring review game based off of Hollywood Squares.

A review game for factoring trinomials.

This activity has the students writing answers in different sections of the paper. Then students fold it up, glue/tape it, and it will make an actual cube to hang up in your room. This can be modified for other classes and topics. Take a look.

Welcome to the wonderful world of Algebra 1 Online!
This course contains both content that reviews or extends concepts and skills learned in previous grades and new, more abstract concepts in algebra. Students will gain proficiency in computation with rational numbers (positive and negative fractions, positive and negative decimals, whole numbers, and integers) and algebraic properties. New concepts include solving two-step equations and inequalities, graphing linear equations, simplifying algebraic expressions with exponents, i.e. monomials and polynomials, factoring, solving systems of equations, and using matrices to organize and interpret data.

However, facility in the use of technology shall not be regarded as a substitute for a student’s understanding of quantitative concepts and relationships or for proficiency in basic computations. Students will also identify and apply real-life applications of the mathematical principles they are learning to science and other disciplines they are studying.
Mathematics has its own language, and the acquisition of specialized vocabulary and language patterns is crucial to a student’s understanding and appreciation of the subject. Students are encouraged to use correctly the concepts, skills, symbols, and vocabulary identified in the course.
Problem solving is integrated throughout the different components of the curriculum. The development of problem-solving skills is a major goal of the mathematics program. Instruction in the process of problem solving will help students develop a wide range of skills and strategies for solving a variety of problem types.
