My son LOVED LM. I wasn't sure whether to get it, and we watched all through the ten day trial in two days and I gave in

Then he lost interest a little. Now he doesn't seem interested at all. I think the problem is that we did the doman method for numbers and touched on equations, and it takes nearly 50 days to get to the equations in LM - at first it was new and interesting, but he knows the numbers and we've only done two days of equations.
Then I downloaded a Little Pim set for LM. Boy did that get his attention! He sits shouting 'Pim' at the screen the whole lesson! I don't know how much he's paying attention to the lesson, but anything is better than nothing, I just have to remember to go through the sections before hand and select Pim on most of them. I leave one or two for variation, but he loses interest if Pim doesn't make an appearance!
Try taking a favourite charcter for maths. If you are using LM, this is easy. If you are using cards, it is going to take a bit of effort (maybe stick to numbers 1-20, or even 1-10 and do lots of equations). I can't believe the change its made for us. Those dots must get a bit boring, after a while!
