Students apply definitions and theorems to verify special quadrilaterals using coordinate geometry. They apply the slope formula, the midpoint formula, and the distance formula to justify that a given quadrilateral is a parallelogram....

10 this geometry learning exercise, students identify the different angles created by polygons and name the shape created based on the number of sides. There is an answer key.

Learners analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationship

Students participate in a two-week real-life math unit. In pairs, they calculate salaries, taxes, and a budget, plan a vacation, buy insurance, make a will, and design a room. They conduct Internet research to plan the vacation, and...

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

Students arrive at a verifiable rule, or set of rules, to handle all addition situations with signed numbers.

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 explain functions.  In this function lesson, students solve functions.  Groups of students develop strategies to perform operations with functions.  They write test questions using functions which include all...

In this ideal gas law worksheet, students watch a demonstration using liquid nitrogen, a plastic 2 liter bottle and a garbage can of water that excites students to use the ideal gas law to solve problems. Students analyze the results of...

Learners graph and solve quadratic equations. In this functions lesson, students analyze a quadratic equation using three points on a curve to define the graph of a quadratic function. They find the vertex and intercepts of the graph.

Students use statistics to solve problems based on the spread of disease.  In this disease lesson students study the role that viruses and bacteria play in the spread of diseases and explain pandemics. 

Students investigate positive and negative numbers using lima beans as a concrete model.

Pupils explore the relevance of water quality monitoring in relation to a local wetland ecosystem. They conduct standard water quality tests using wet tests and CBL calculators and probes. Student record and interpret the results.

Students identify oviparous animals. They brainstorm a list of animals that lay eggs, read "Chickens Aren't The Only Ones" by Ruth Heller and then add to the list. Students complete a booklet that shows an egg and an oviparous animal.

Learners explore the Census Bureau's Homepage on the Internet to gather data regarding trends in population, poverty guidelines, and social characteristics between caucasians and minorities. The data is used to investigate evidence for...

Students explore dinosaurs. Students determine the relationship between leg length, stride length, and speed in humans and bipedal dinosaurs. Students analyze collected information. Based upon the data, dinosaur tracks, and fossils,...

Students, after reading the Drag Equation page from the NASA Web site, demonstrate an understanding of this equation and how drag is dependent on the variables included in the equation.

Young scholars, after reading an explanation from a NASA Web site, demonstrate an understanding of the text by applying it to questions involving the Thrust to Weight Ratio and Excess Thrust of an aircraft.

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.

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

Students experiment with Hiker program to practice real world applications of linear functions and develop their understanding of expressions, relationships, and manipulations involved in writing and graphing linear equations in...

Students explore the concept of linear equations. In this linear equation instructional activity, students change parameters of an equation and notice the effect it has on its graph.

Students explore the concept of patterns. In this patterns instructional activity, students use applets to manipulate tessellations. Students predict the next number in a sequence by recognizing patterns.

Ninth graders participate in a lesson focused on the concept of basic statistics. They find the mean, median, and mode of different data sets. More advanced students could practice creating a bell curve from the data.
