It's not so straightforward — lines can model a variety of applications. Pupils experience linear relationships within the context of science, including Hooke's and Ohm's Laws. Class members got a taste of motion and speed from the...

Linear equations are all about form. The fifth part in a unit of nine works with the different equivalent forms of linear equations. Class members become familiar with each form by identifying key aspects, graphing, and converting...

The Great Fire by Jim Murphy provides the text for a study of the Chicago fire of 1871. The plan is designed as a close reading activity so that all learners have the same background information require for writing. Richly detailed, the...

Students create a design of a circle. In this geometry instructional activity, students identify the measure of the diameter and radius of a circle. They graph and analyze their collected data and write equations based on direct variation.

In this Algebra II learning exercise, students are given a test of twenty-three problems regarding Rational Expressions and Rational Equations.  Some of the questions are multiple choice, while others are word problems or problem...

Beginning in 1851, Thoreau recorded the dates of the first spring blooms in Concord, and this data is helping scientists analyze climate change! The culminating instructional activity in the series of four has pupils graph and analyze...

The behavior of a rational function near a vertical asymptote is the focus around this trip up a river. Specifically, numerical and graphical understanding is studied. The canoe context pushes the variables as numbers, rather than as...

Um may be the atomic symbol for confusion, but it won't be needed in this lesson. Scholars rotate through seven stations completing experiments, hands-on activities, writing exercises, and analysis. Stations include material on...

Learners explore the different types of vertebrates found in their area. In this environmental science lesson, students perform a case study on the Common Raven. They analyze data collected from research and create charts and graphs.

In this Algebra II worksheet, students assess their knowledge of rational algebraic expressions. The three page worksheet contains a combination of twenty-three multiple choice, short answer, and word problems. Answers are not...

Practice with unit rates, proportions, and ratios when Carlos purchases an amount of bananas. Learners must interpret a graph to decide whether points on the same line represent similar proportional relationships. Use with lesson plans...

Eighth graders participate in two data collection activities that involve direct and inverse variation. In the pre-assessment, 8th graders categorize numerical, graphical, and verbal representations as linear or nonlinear and determine...

Ever wonder if you can trust the pump that pumps your gas? Budding mathematicians use video evidence to analyze the cost-per-gallon ratio at different intervals for three different pumps. Their goal is to identify the pump that is...

In this algebra learning exercise, students find the inverse of an equations. They graph their solutions and analyze it. There are 8 questions.

Students use, with increasing confidence, problem-solving approaches to investigate and explain mathematical content. They make and test conjectures. They use tables and graphs as tools to interpret expressions, equations, and inequalities.

Students demonstrate how the moon affects the tides, a neap tide, and spring tides by using their bodies as models. After students observe the model they created, they draw and label the diagram on a provided worksheet. They then log...

Students gather high and low temperature readings through email. In this temperature graphing instructional activity, students use a spreadsheet to input data for a graph. students interpret the graphs to compare and contrast the data...

Learners investigate the slope of various stairways through a "news report" approach and employ mathematical knowledge of applied slope to report on wheelchair accessibility and adherence to Americans with Disabilities Act. They...

Scholars show what they know about data collection and analysis with an activity that examines a smaller population of Houghton, Texas. Independently or in pairs, learners identify their research question, gather, graph, and analyze...

A brilliant resource is at your disposal. Future consumers investigate and discuss an electric bill. Given only partial information, they estimate the monthly bill. They then consider how tiered pricing will affect the bill.

Students explore the concept of piecewise functions. In this piecewise functions activity, students graph piecewise functions by hand and find the domain and range. Students make tables of values given a piecewise function. Students...

Students study the components of a bedrock geology map through a hands-on activity involving a cookie and graph paper.

Students analyze data about various climates in Canada. For this data analysis and climate lesson, students use Canada Year Book 1999 to complete a worksheet and make connections between precipitation and temperature in different climates.

Fifth graders analyze temperature variations throughout the world by using computer graphing of select major national and international cities.
