My year 9 year old son has just been diagnosed with dyscalculia. I am not finding the school particularly helpful so have started looking for things we an do at home. I have found a kit called Addacus which is basically items that can be used to show maths as well as worksheets etc. Has anyone used it? It's over £100 per kit and it loons like there are 3 kits so I don't want to make an expensive mistake.
