This stand-alone Shockwave program simulates bombs falling on a city via two methods (rudimentary guidance system versus uniformly random), and students are asked to apply data analysis to determine which simulation method is which.

Sequences and Series of Functions

An interactive and visually engaging mathlet for exploring different types of convergence of sequences and series of functions.

Generating Tables to Demonstrate Limits

This mathlet demonstrates limits visually by showing values for f(x) as x approaches a given constant c.

Standard Deviation Applet

In this applet, a user fills in a grid to create a distribution of numbers. The applet displays the size of the standard deviation and the position of the mean in the distribution. An activity is provided to facilitate the use of the applet to investigate standard deviation.

ORF Finder

A Biological ESTEEM module in the Genetics Category. This workbook performs six-frame translation on a short user-input nucleotide sequence and highlights the position of stop codons.

History of the Math and Architecture Project

An article by the faculty advisor of the students who created the Math and Architecture Project, explaining how the project came about.

Probability Aquarium

Simple probability concepts such as sampling with or without replacement are illustrated in this engaging tiered activity for beginning students and future teachers of probability.

SIR Model

A Biological ESTEEM module in the Epidemiology Category. This worksheet implements an SIR (Susceptible/ Infected/ Resistant) model of epidemiology for vector-borne diseases.

Creating Mathlets with Open Source Tools

In this article we present a collaborative environment of open source tools around the dynamic mathematics software GeoGebra that gives educators the freedom to create new and modify existing materials in an online community.

Complex Function Grapher

A mathlet for constructing graphs of functions of a complex variable, using color as the fourth dimension.
