'Do it instead of'...rather then 'As Well As'
That is my new motto. Part of the problem when integrating ICT into teaching and learning is that teachers are treating it as an add on! In some cases there are still classrooms that are operating with only one computer and/or another one barely working but most schools I visit nowadays have between 2-4 computers in their class.
Think of this
Instead of giving your reading or maths group a worksheet, create the worksheet in Kidspiration, Inspiration, Word, PowerPoint (or whatever you would like to use). Make one child in the group the mouse operator, one the keyboard, one writing on a whiteboard, one on a calculator or anything else you can think of, then the children can swap. You can have at least 3 children on one computer. So instead of writing on a worksheet they are working together using the computer.
Another example where this works well is in Art. Whatever the children are doing in art, someone can be doing the same thing using the computer. Artrage has pencil, paintbrush, crayon, felt tip and pastel tools. Experiment with the pencil and you can even do shading! A teacher once said to me "we are doing weaving, how can we use the computer to create a woven pattern?" My answer was 'use Word or PowerPoint with autoshapes and colours'. Find graphics with textures and weave with them. Children will learn a lot of computer skills and use a lot of problem solving doing this type of exercise.
The other important thing to remember is that not everyone in the class has to do that same activity on the computer, maybe in art this week it is this group of children, next week it is another group of children with maybe a different computerised art activity and so on.
