This unit is the fourth in the MSXR209 series of five units on mathematical modelling. In this unit you will be taken through the whole modelling process in detail, from creating a first simple model, through evaluating it, to the subsequent revision of the model by changing one of the assumptions. The problem that will be examined is one based on heat transfer. This unit assumes you have studied Modelling pollution in the Great Lakes (MSXR209_1), Analysing skid marks (MSXR209_2) and Developing

What is ‘e-commerce’? This unit will look at typical application areas including the internet, supply chain management and online auctions. It will also help you to understand the underlying technologies used to implement e-commerce applications before looking at some of the problems that can be encountered when developing distributed e-commerce systems.
What causes seismic waves and how do they travel through the Earth? This instructional tutorial, part of an interactive laboratory series for grades 8-12, introduces students to seismic waves caused by earthquakes. Students answer questions as they move through the tutorial and investigate how P and S waves travel through layers of the Earth. In one activity, students can produce and view wave motion in a chain of particles. Scored student results are provided. A second activity introduces Love
Learning how to learn: a process we all engage in throughout our lives, but no single method of learning guarantees success. This unit aims to make the process of learning much more explicit by inviting you to apply various ideas and activities to your own study as a way of increasing your awareness of your own learning. Most learning has to be an active process – and this is particularly true of learning how to learn.
State Data Map
Information can be represented in many ways; this applet allows the user to represent data about the states using color. The state with the highest data value is darkest; other states are shaded proportionally. Several sets of data are already entered and available for examination: state population, land area, representatives in Congress, gasoline usage, and more. Users can eliminate the data from any state in order to note the consequences, or enter their own data. A box plot and table accompan
A set of 15 videos showing brief lessons on geometry definitions (polygons, angles, tangents) and basic applications (finding areas, using the Pythagorean theorem). In these 2 to 10-minute lessons, a teacher uses blackboard drawings and clear explanations to deliver mini-tutorials.
Reading in the Mathematics Classroom
Written by Diana Metsisto, a middle school mathematics coach, this online chapter involves both the “why” and the “how” of integrating reading in the teaching of mathematics. She begins with a brief but insightful summary of the theory, then offers a number of concrete classroom strategies. This is a chapter from Literacy Strategies for Improving Mathematics Instruction.

A decade ago, the possibility of a link between the MMR vaccine and autism hit the media. Fear of the vaccine spread rapidly and, despite an almost unanimous consensus that the claim was unfounded, still persists today. In this unit, we’ll examine why this controversy took on such a life of its own and why parents still agonise about the vaccine.
Using NBA Statistics for Box-and-Whisker Plots
In this lesson, students use information from NBA statistics to make and compare box-and-whisker plots. After reviewing the concepts of minimum, maximum, median, upper quartile and lower quartile, students create three box-and-whisker plots for sets of data on the heights and weights of basketball players. In each case, the students consider the effects of changing one piece of the data, such as eliminating the height of the tallest player. Detailed instructions for the lesson, assessment option
Every Breath You Take
In an activity designed to help students develop number sense, each student estimates the number of times s/he breathes in one hour, and the class graphs the estimates, finds the mean and median of the estimates, and discusses outliers. Students then brainstorm how they could find out how many breaths a person actually takes in a day—and implement their strategies.
Accessing and Investigating Population Data
In this activity, students investigate population projections from 1990-2100 using data from the U.S. Census Bureau Web. Using the five specific population pyramids, students investigate population projection data for the United States over a 110-year period. They examine how the population data is distributed over time and explain what factors might contribute to these trends. An activity sheet and thoughtful questions, included in the lesson plan, guide the class investigation.

Students are given the timetables of two trains, each going along the same route, but one coming and the other going. Carefully crafted questions ask students to create and analyze a graph of position vs. time for one train, then to explain mathematically the ways a graph of the other train’s run should resemble the first graph. Finally, they create the second graph and try to explain the unexpected discrepancies between the two graphs. A full solution and scoring rubric are included.
A Whole-School "Read" Creates a Reading Community
A whole-school read solved a potentially disruptive problem by providing a common reading experience that addressed student diversity through a school-wide, interdisciplinary, year-long event at Hand Middle School.
