High schoolers explore natural selection. For this genetic adaptation activity, students discover why certain traits continue and some traits disappear. High schoolers discover how species evolve and change. Resources are provided.

Students collect data from one of three selected biomes. Data are then organized and statistically analyzed. This project engages students of different backgrounds grouped cooperatively in a relevant outdoor hands-on learning experience.

Students explore change represented in graphs comparing distance and time. They exchange and share their graphs. Students interpret and create distance versus time line-graphs, and write stories based on these graphs. They interpret a...

Pupils are introduced to the basic ideas needed for understanding linear functions.

Students explore the concept of functions. In this function lesson, students determine if the graph is a function by using the vertical line test. Students use an applet to explore the vertical line test on a variety of graphs.

Third graders measure their feet and their parents' feet, record data on computer-generated graphs, and calculate and record mean, median, and mode.

Students investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.

Students explore the concept of modular arithmetic and cryptography. In this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their ciphers...

Students investigate modular arithmetic and how to use it to solve real world problems. In this modular arithmetic lesson, students use computers to work on modular arithmetic after a teacher guided lesson. They complete guided practice...

Learners classify, add, subtract, and factor polynomials. In this polynomials lesson, students classify polynomials by creating their own system. During a discussion, the class decides on a common system. They add and subtract...

First graders explore counting and classification. They sort leaves, create graphs, write sentences for the data in the graphs, develop graphs for shapes, favorite animals, birthdays, and participate in a die prediction game.

Young scholars explore number relationships by participating in a data collection activity. In this statistics lesson, students participate in a role-play activitiy in which they own a scrap material storefront that must replenish...

Students are introduced to plotting functions on the Cartesian coordinate plane seen several categories of functions, including lines and parabolas

Students determine the amount of earth that needs to be removed from the Mississippi and the amount of time it takes the Army Corps of Engineers to complete a dredging project. Given specific dimensions of a channel, calculations are...
