Visualizing mathematics for junior high school is a computer oriented learning environment for studying mathematics in the 7th to 9th grades.   The curriculum The focus of algebra studies is the concept of function: Using the concept of function, the student can learn about processes and phenomena in the world around us. The concept of function can be used for building the whole fabric of skills and concepts in algebra. The concept of function appears in all algebra topics and organizes them in a logical sequence. The concept of function can be represented in four different ways: verbal, graphic, numeric, and symbolic representations. Forming the connections between the different representations leads towards a deeper and wider understanding, and allows diversified learning processes and varied ways of feedback. The study of geometry is based on inquiry activities by way of conjecturing, and then checking the conjectures, generalizing, and proving them.

Sequence of topics: 7th grade Acquaintance with the concept of variable, use of variables and learning the algebraic notation. (software: Algebra Patterns). Forming relations between verbal and graphic descriptions. (software: Algebra Sketchbook). Forming relations between the four representatons of the function - verbal, graphic, numeric, and symbolic. (software: Algebra Patterns, Calculus Unlimited and Functions' Web Book). Linear functions in various representations, simplification of expressions. (software: Calculus Unlimited and Functions' Web Book).

8th grade More profound learning of the concept of function: families of functions, exponential functions and rational functions. (software: Calculus Unlimited and Functions' Web Book). Comparisons of functions: equations and inequalities in one variable. (software: Calculus Unlimited and Functions' Web Book). Word problems in one variable. (software: Calculus Unlimited and Functions' Web Book). Geometry: triangles. (software: The Geometric Supposer and The Geometer's Sketchpad).   9th grade Quadratic functions: the meaning of the quadratic function and families of functions. (software: Calculus Unlimited and Functions' Web Book). Functions in two variables: a system of functions in two variables. Geometry: quadrangles and circles. (software: The Geometric Supposer and The Geometer's Sketchpad).
