A happy discovery on Twitter, a conversation with **Christian Bokhove** of Southampton University led me to another home for the Wisweb widgets. Try the **Digital Mathematics Environment **from the Freudenthal Institute.

**To access the resources mentioned here:**

**Choose Open DME for student**
**Login as guest. **
**Explore Secondary Education (also the DME Widget list)**

A guest login has restrictions but you will be able to explore and use resources, many of which make excellent demonstrations.

A site very well worth exploring to become familiar with what is available and one I’ll return to.

Some examples follow:

Choose Secondary Education, Algebra and also the Algebra Widgets to explore resources such as the following :

Algebra Arrows illustrated above is excellent for exploring functions. Form inputs, operations and output by dragging them onto the main workspace, connect them up and optionally connect to a graph. Click inside any of the elements to change the content.

The Digital Mathematics Environment has much more than the original Wisweb applets – a quick glance at Secondary Education shows we have resources to explore.

Choosing Secondary Education/Algebra/Exercises – Equations/Linear equations led me to another favourite. A whole series of these exercises is available. I like the way the steps and working are clearly shown

There are useful demonstrations that could work well in class:

Operations with Letters – Using Machines

Operations with letters – test yourself

Formulas for Graphs – Linear Functions

Choosing Secondary Education – Geometry will give you the following choices:

I am very happy to see widgets such as Building Blocks again. This is useful for demonstrating plans and elevations. I discovered I could clear a block by selecting both left and right mouse buttons simultaneously.

Statistics and Probability widgets includes a widget illustrated here on the Normal Distribution; try experimenting with the various variables.

Probability Trees could be useful for creating diagrams as the basic diagram is very easy to set up – simply enter the number of branches you require.

(If you are using one of the older browsers and have up to date Java, you can still use the **Java versions of the Wisweb Applets.**)
