No they're not forced to do that, i mean partitionning in Year 4.
My year 4 DDs spent about an hour yesterday doing 10 addition sums. The sums were, for eg, 356 + 223. Their instructions were that they had to use the partitioning method and so they dutifully went through the whole laborious process which took almost 10mins per sum because of the amount of writing out of figures that the process requires.
They are both bright girls, in top band for maths and were able to add 3 digits together (at home with me) in the old fashioned way (356
223) over a year ago.
So advice please. Should they still be being forced to do partitioning in Year 4 or should they ,by now, be able to choose an addition method to suit? Is there really a benefit to partitioning if you actually understand how to use the old method (including carrying numbers)
