Posts like this keep reinforcing my distaste for the irregularities of English spelling. They make children's lives far more stressful than need be or should be.
The word your dc is getting are from the 100 most used English words. Sadly, quite a few of them have irregular spellings.
49 are not tricky to spell:
a, and, as, at, had, has, that, an, back, can,
in, is, it, if, did, him, his, with, big, little, this, will,
get, them, then, well, went,
not, on, from, so, go, no, or, for,
but, much, must, up, just,
came, made, make, I, like,
our, out, about, over.
51 are tricky in various ways:
^he, of, the, to, was, first, her, off, they, new,
all, be, been, here, see, are, have, one, said, we, you, by, my, call, before, come, could, do, down, into, look, me, more, now, only, other, right, she, some, their, there, two, when, want, were, what, where, which, who, your, old.^
As soon as children start to do any independent writing, they need to use them. So learning them quite early on is quite a good thing, but many children find them hard to cope with.
I hope the above helps u to understand why your dc is getting those spellings to learn, but please carry on doing all u can not let your dc get stressed about them.
