Bluebell, cannot wholly agree re Maths teaching now. Some of it found less than helpful, "chunking" in division for example. However open number lines, learning to do calculations on paper the way you do them in your head by adding the tens, then the units and adding both together and learning number bonds to 10 and 20 all helped me to understand the way numbers work. I was always "hopeless at sums" but was able to teach this sort of thing with confidence and I hope imparted that to those who struggled. Whereas carrying and borrowing and all that stuff we learnt in the fifties, just eluded me. Those who are natural number crunchers may not need this, the dysnumerate amongst us need all the help we can get I believe.
