Ds2 is G&T in maths but this year has been the only year (y4) that he has not made as much progress as we would have expected (not against school criteria but against his own normal progress). He is fine but in previous years he was generally well supported and encouraged by teachers. The last year he has felt generally not motivated or challenged. I am wondering if it's just because his teacher isn't very good at teaching maths, or teaching G&T children, or could it be because of changes to the curriculum? Any similar experiences elsewhere?
