Splash Maths is a learning software  for children who have limited mobility and who don’t find it easy to write in their maths books. It comes with all sorts of tools to make geometric patterns and to fill out numbers on graph paper which can then be printed off.  When Splash Maths  is first opened it looks quite complicated but these two tutorials make it a little simpler. There is also a link to the website below.  Having had a quick look it might be easy to adapt the worksheets before attempting to create a worksheet from scratch for use with a child with mobility issues, but how about using this tool to make printable activities for the whole class?

This is the website too
