# Software and Supporting MEI Resources

There are many programs and web resources that can be used in the teaching and learning of mathematics; many of these are free to download. MEI has produced resources to support the use of several of these software programs in the classroom. Links to free MEI resources will appear in the software sections below:

## Autograph

Autograph is an essential tool for the Mathematics classroom allowing for statistical, 2D and 3D graphs to be plotted easily.

Please follow the links below to access MEI resources supporting the use of Autograph:

## Desmos

Desmos is is a free graphing calculator that is available online or as an Android/iOS app. There are also lots of free teaching activities and materials on their website: www.desmos.com/

We have produced investigative tasks to help integrate the use of Desmos into A level Mathematics. These tasks are designed to be used on the app on a variety of devices:

## Excel

Spreadsheets are a very useful tool in the Mathematics classroom and can be used for many types of investigations.

Students are likely to benefit greatly from learning how to enter formulae into spreadsheets. This can help them remember important formulae and the technique will obviously be useful to them in other areas. In addition to this they will have to learn the specific syntax of the package they are using; this will allow the importance of conventions for syntax to be emphasised. A good example is to have students set up a spreadsheet that solves the quadratic equation ax2 + bx + c = 0, when the values of a, b and c are entered in separate cells. For more details see NCETM Mathemapedia: Spreadsheet Algebra

The 'Forms' toolbar on Excel allows for scroll-bars/sliders to be added to worksheets. These are excellent for displaying the effect of varying parameters in a situation. They work well with IWBs as they can be operated from the board, removing the need for key-entry.

## GeoGebra

Geogebra is free mathematics software featuring interactive graphics, geometry, algebra and spreadsheet. Hundreds of thousands of prepared materials are available on the site.

MEI is a GeoGebra Institute supporting teachers through workshops, professional development materials and creation of resources. For details of all of MEI's work with GeoGebra see: GeoGebra Institute of MEI.

We have produced investigative tasks to help integrate the use of GeoGebra into A level Mathematics

## LINDO

LINDO (Linear, INteractive, and Discrete Optimizer) is a Linear Programming package which is needed for the computer-based module Decision & Discrete Computation. It is also suitable for use in teaching the other modules in this strand. LINDO can be ordered from MEI using the LINDO order form; you can also read the LINDO manual.

## Tarsia (Jigsaw Software)

Formulator Tarsia (previously known as Jigsaw 2005 or Activity Template Software) allows you to create mathematical jigsaws, dominoes and other card-sort activities in an easily printable form. It is free to download from Hermitech Laboratory.

## TI-Nspire™

TI-Nspire is a suite of learning tools, available as a handheld device and as computer software.  Both the handheld and software have Calculator, Graphs, Geometry, Lists & Spreadsheets, Data & Statistics and an interactive Notes applications.  The handheld includes a Touchpad, which operates just like a computer mousepad, to aid navigation and manipulation of objects. A CAS (Computer Algebra System) version of TI-Nspire is also available. Resources, including lesson ready TI-Nspire documents, are available free at Nspiring Learning.
