Lesson: Introduces students to arithmetic and geometric sequences. Students explore further through producing sequences by varying the starting number, multiplier, and add-on.
Activity: Graphically determine the value of two fractions you have chosen (which are represented as points on a number line). Graphically find a fraction whose value is between your two fractions (using an arrow on the number line as a guide), then determine its value. Bounded Fraction Pointer is one of the Interactivate assessment explorers.
Activity: Graphically determine the value of two given fractions represented as points on a number line. Graphically find a fraction whose value is between the two given fractions, then determine its value. Fraction Finder is one of the Interactivate assessment explorers.
Activity: Visualize fractions by coloring in the appropriate portions of either a circle or a square, then order those fractions from least to greatest. Fraction Sorter is one of the Interactivate assessment explorers.
Activity: Enter two complex numbers (z and c) as ordered pairs of real numbers, then click a button to iterate step by step. The iterates are graphed in the x-y plane and printed out in table form. This is an introduction to the idea of prisoners/escapees in iterated functions and the calculation of fractal Julia sets.
