Teach your students how to create and interpret bar graphs

Learning Intention / Overview

In this activity students will develop an understanding of bar graphs.  A bar graph uses horizontal or vertical bars to organize and display data for quick easy generalizations.  The bars represent amounts or qualities of things being compared.

Microsoft Maths 4.0 - Now Totally Free for Teachers and Students

Microsoft Mathematics provides a set of mathematical tools that help students get school work done quickly and easily. With Microsoft Mathematics, students can learn to solve equations step-by-step while gaining a better understanding of fundamental concepts in pre-algebra, algebra, trigonometry, physics, chemistry, and calculus.

Microsoft Mathematics includes a full-featured graphing calculator that’s designed to work just like a handheld calculator. Additional math tools help you evaluate triangles, convert from one system of units to another, and solve systems of equations.

For the first time this is now totally free and available here

Lesson Plan: Surveying Data and Creating a Graph

This is a single lesson aimed at upper primary aged students (aged 9 -12 ) about collecting data, creating graphs and analysing the data you have collected.  All of the resoruces are contained within the planner.

•This lesson will assist students in further developing their knowledge of fractions, decimals and percentage.

•The data collected can also be used in developing an understanding of graphical representation in the form of graphs; for example: Pie, linear, bar graphs etc.

Google Public Data Explorer - An excellent maths resource

Just found this today and I would definitely recommend taking a look at it with your students especially if you are looking at chance and data.

Google Public Data Explorer, a part of Google Labs experiments, is a tool that helps you explore through and visualize public datasets that are made available by government and other agencies that track stats, from around the world.

There are a number of datasets available. You can check out the government debt in Europe or visualize the unemployment rate in the United States, see how the US population is growing or the variations in prices of natural gases around the world.

It offers four kinds of visualizations for most of the datasets: line chart, bar chart, map or bubble chart. You can easily switch from one chart format to the other.

You could also compare the data for specific countries for datasets that aggregate data from an entire continent. For example, in the graph, I’ve compared the broadband penetration rate in specific countries in Europe.

The charts and maps can also be embedded in your website or blog. Overall, a nice tool for students and scholars and could definitely aid in their research on a topic.
