4-3.1 Analyze numeric, nonnumeric, and repeating patterns involving all operations and decimal patterns through hundredths.

Patterns in Fractals	Lesson: Introduces students to the idea of finding number patterns in the generation of several different types of fractals.
Cantor's Comb	Activity: Learn about fractions between 0 and 1 by repeatedly deleting portions of a line segment, and also learn about properties of fractals. Parameter: fraction of the segment to be deleted each time.
Pattern Generator	Activity: Recognize patterns in a series of shapes, numbers, or letters. After determining the pattern, the student fills in the missing pieces. Three levels of difficulty are available.
Sierpinski's Carpet	Activity: Step through the generation of Sierpinski's Carpet -- a fractal made from subdividing a square into nine smaller squares and cutting the middle one out. Explore number patterns in sequences and geometric properties of fractals.
Tessellate!	Activity: Create a tessellation by deforming a triangle, rectangle or hexagon to form a polygon that tiles the plane. Corners of the polygons may be dragged, and corresponding edges of the polygons may be dragged. Parameters: Colors, starting polygon.

4-3.2 Generalize a rule for numeric, nonnumeric, and repeating patterns involving all operations.

4-3.4 Translate among, letters, symbols, and words to represent quantities in simple mathematical expressions or equations.

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.

4-3.6 Illustrate situations that show change over time as either increasing, decreasing, or varying.

Graphs and Functions	Lesson: Demonstrates the connections between formulas and graphs.
Introduction to Functions	Lesson: Introduces the basic ideas needed for understanding functions.
Slope Slider	Activity: Manipulate a linear function of the form f(x)=mx+b using slider bars. Explore the relationship between slope and intercept in the Cartesian coordinate system.
