These are some ActivStudio flipcharts that I created for teaching integer operations.

Note that some of the pages are from flipcharts that I downloaded from the Promethean Planet website.

To view these flipcharts, you need to have ActivStudio on your computer. Or ...

Go to
http://www.prometheanworld.com/server.php?show=nav.16874
and download ActivInspire Personal Edition. You may have to register first.

It is a big download, about 230 MB. But it is free. And you are allowed to use this software in your classroom with any IWB, or even with just a computer and data projector.

Once it is installed, you can then open the flipcharts. And you also have access to hundreds (thousands?) of other teacher-created maths flipcharts at http://www.prometheanplanet.com/

You may have to register again as this is a different Promethean website, but once you are registered, click on Resources / Lessons etc. You will find a large collection of teacher-created Maths flipcharts. The quality varies from great to ... well, useful for ideas.

This resource attempts to emulate a cell phone calculator. The teacher can demonstrate how to use the simple calculators to do useful real world maths. At the moment 2 types of real world questions can be generated by the resource: percentage discounts and area.

The computer randomly chooses 4 digits. Use the four digits and the arithmetic functions - Addition, Subtraction, Multiplication and Division (and also Exponents and Parenthesis) to form the numbers from 1 to 10.

Below are two TI-Nspire documents from Spencer Williams that show visually the operations of adding and subtracting fractions. There is also a pdf file to support the use of these in the classroom. Thanks, Spencer, for sharing these.
