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: A more advanced version of Slope Slider, this activity allows the manipulation of the constants and coefficients in any function thereby encouraging the user to explore the effects on the graph of the function by changing those numbers.
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.
