Does anyone know of any good online programs that help to improve English? I have used Reading Eggs which is brilliant for help with reading, and my DS loves that as its very engaging. However I am looking for something similar to this which will help him with grammar, punctuation, sentence formation etc etc. There seem to be a lot of programs for maths (e.g., Maths Whizz, Komodo Maths, Mathletics), but has anyone any ideas for an equivalent for English?
