Curated OER
Logic and Proof Writing
Students define inductive and deductive reasoning and write two column proofs. In this geometry activity, students analyze arguments and draw conclusion. They define steps necessary to arrive at the correct answer when completing proofs.

Chart Your Course
Middle schoolers 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...
Curated OER
Introduction to Linear Functions
Students are introduced to the basic ideas needed for understanding linear functions.
Curated OER
Functions and the Vertical Line Test
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.
Curated OER
Clock Arithmetic and Cryptography
High schoolers 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.

Modular Arithmetic
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...
Curated OER
Polynomials and Factoring
Students classify, add, subtract, and factor polynomials. For 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...
