Designed specifically for math instructors, the seventh workshop of a 15-part series allows time to explore Webb's DOK, ponder open-ended questions, and create lessons to apply what is learned. Teachers craft high-quality math problems...

A summary of error and uncertainty considerations, presented at an annual mathematicians' meeting. Not terribly deep, and covers the gamut of concerns about modeling of the real world with inadequate data or math tools. On target. This...

A collection of activities where students investigate mathematical modeling. Activities involve different types of functions, how to examine context and decide on a model, and limitations.

Provides a good discussion of how and why models are used in Mathematics to represent problems in the real world. It explains different ways to model a problem, e.g., with a formula or an illustration, and what can be learned from them....

This is a mathematical modeling task aimed at making a reasonable estimate for something which is too large to count accurately, the number of leaves on a tree, taking into account the tree size and the density of the leaves. Aligns with...

Bin packing is a very appealing mathematical model. This article discusses several bin packing problems and the various methods for solving them.

The resource investigates exponential functions and models. Students learn about the concepts through notes and examples. A chapter quiz, review exercises, and chapter summary are included.

Using a mathematical model, 4th graders will be able to visually see the process of how to multiply a fraction by a whole number to find its product in order to gain a deeper understanding to ultimately be able to do it on their own.

This resource presents information about the mathematical model of forces on bridges. Examples of a classroom activity are provided. The resource also involves using matrices to solve systems of equations.

This appendix should be consulted after first reading "Welcome to Economics." Though economics is not math, there is no important concept in this course that cannot be explained without mathematics. That said, math is a tool that can be...

This resource explores instructional practices for using think-aloud in English language arts, mathematics, science, and social studies classes. Think-Aloud examples are provided in both science and math. Download and print a resource...

Contains plans for five 50-minute interdisciplinary lessons that ask students to write about math-related, informational books such as "Actual Size" (Jenkins, 2004) and "If You Hopped Like a Frog" (Schwartz, 1999). Students use books...

The Contemporary Mathematics in Context series provides a common core of broadly useful mathematics for all students. The discrete mathematics strand develops student ability to model and solve problems involving enumeration, sequential...

The topic summary outlines linear functions and models. Some topics reviewed are domain, mathematical model, slope, and linear regression. The resource consists of definitions, notes, and examples.

In order to determine how effective solar panels would be at various times of the year, it is important to know the amount of daylight at a given location. Students are asked to find an appropriate function that serves as a mathematical...

In the July 2013 issue of United Airlines' Hemisphere Magazine, a pilot responded to a question about how far in the distance he could see at different altitudes. The solution involved right triangles, lines of tangency to a circle, and...

In this task, students are asked to make a mathematical model and determine if it is possible to see a point on the surface of the Earth that is 85 miles away, and well below sea level, from the top of a mountain. The curvature of the...

This task gives students a chance to explore the effects of the Earth's tilt and rotation using a simple geometric model of Earth-Sun interaction that shows why the seasons occur. Aligns with G-MG.A.1.

This task is about an online mathematics organization that is trying, over a four-year period, to generate 2,000 math problems that cover all grades. This real-life modeling task could serve as a summative exercise that draws on many...

In this task, a model airplane pilot is practicing flying her airplane in a big loop for an upcoming competition. The task could serve as an introduction to periodic functions and as a lead-in to sinusoidal functions. By visualizing the...

Use this virtual model to simulate the basic operations and accuracy of a micrometer while manipulating the physical parts of the object.

National Council of Supervisors of Mathematics: linear function provides a teacher learning module on how to effectively teach linear function and resources that would help to do this.
