This is certainly how the school my children goes to teaches it (after all the home education recently I now have a pretty good idea how they teach!) And yet, I get the impression that most of the children still find the concept of fractions hard. Mine (8 and 10) do have that conceptual understanding but that doesn't mean that they are totally fluent with adding, dividing fractions etc. yet despite both being at the top of their years at school in maths. I reckon 99% of 7-year olds would definitely struggle with those sheets. I think my 10 year old would enjoy them (he likes maths a great deal!) but that my 8 year old wouldn't. On the other hand I think it's good to have high expectations of what children are capable of understanding mathematically - they often surprise you!
