5 The size of the problem

The post-16 maths support community has two large sources of resources that contain inaccessible images; Mathcentre and Helm.

The mathcentre website, now maintained by the sigma network, host support materials for anyone looking for post-16 maths help.

HELM (Help Engineers Learn Maths) is a popular resource that has already been converted to HTML. The next stage now is to recreate the images as digital objects.

5.1 Scale of the problem

There are over 1000 images embedded in the mathcentre resources. The HELM resources have about 900 images. Most will be easy to recreate as a digital object. Some will be tricky here is a flavor of the type of object still to be done.

5.2 Types of image

Fortunately, for the majority of the images in these resources, it is relatively easy to create a digital object. Below is a categorisation of the difficulty of creating these objects with some examples.

5.2.1 Easy ~5mins

Quickly done in Desmos using one equation and some formatting options.

5.2.2 Medium ~15mins

Can be done in Desmos using more than one equation and formatting options.

5.2.3 Hard ~?mins

Can only be done in GeoGebra. Will probably require making and then remaking to make an object that is easily navigable.
