Poor Maths Results

This article on Poor Maths Results was interesting as I heard of this way of teaching maths and came across this article. I found it interesting in that they have done studies to say that ability grouping does not work. During my last few years I have had another look at reading groups as I don't always think that reading abilities groups work, so adjusted my reading programme with good success. However for maths I had not really considered it. I think when they stated that if children are only exposed to lower curriculum than the expectation is low. I question this a bit as  I expect they have to have a certain amount of numeracy knowledge in the first place. With  ability groups they do move on to other levels and I don't think the expectation is low.
 The article also talks about how teachers have to be trained in the way they teach this way without ability groups and I get that. After having a bit of a think about this I think that having the right type of open questions could work. I have many questions though like do you pair them up when attempting these open questions so you get different view points from different levels. How do you ensure that the lower leveled children share their ideas and don't get overwhelmed with the higher ability child's work and just follow their thinking completely or is that okay.
Problem solving in maths is important and can be challenging and a lot of fun for the children and really puts the children's maths skills to test. I need to find more information on this type of teaching to fully understand the practical approach to it.
