Glen Doman says that children lose the ability to subitize after about the age of 2 1/2 but someone on this board suggested changing the settings of little maths so that the dots appear in rows of ten rather than randomly. Apparently this helps older children to visualise the numbers. Another thing that Glen Doman says is that you shouldn't show more than 5 dot cards in one sitting and that you should do at least 3 sittings a day - that way the child doesn't get bored and is left wanting more. This seems to make sense as far as my little boy is concerned as he really doesn't pay attention to the screen when LM is on and to be honest I find it goes on too long myself.
Sorry this isn't a success story for you. I was hoping that LM would be something that would be like the Doman method but take away the need to sort out cards physically as I am quite disorganised and would lose where I was (or even the cards
!)
However, I have read on here that people have revisited little math with older children once the have got the idea of skip counting etc and it has been very helpful.
If you find a way to use LM that works for you please let me know.
