I have been reading with dd and splitting the words up like this, eg for the word mammoth m.a.m (mam)m.o.t.h (moth) and then she puts the mam and the moth together and gets mammoth, school have asked me not to do this and do the letters individually m.a.m.m.o.t.h but with big words like this dd has forgotten the first bit by the time she gets to the end.
Also the word good if dd spells out g.o.o.d she says God.
How can I help her
