How challenging should reading books be?

[Elvisinthechipshop]

My daughter (4, just started reception) has been reading for a while. Obviously she will read at school but I want to keep supporting her learning at home. How hard should she find a reading book for it to be useful? E.g. I sometimes get the 'Read with Oxford' phonics books which have 6-7 stories. I got a new one today and she read all the stories to me swiftly with no help, and answered comprehension questions correctly. Does that mean it's the right level or too easy? Not looking to be super-pushy, but just want to help her progress.

I asked the teacher this in reception as it was lockdown so wanted to be able to identify the right stage. She advised that dd should be able to read 90% fluently and 100% independently (so maybe needing to break flow and sound out 10% but overall do it without input) to be the correct level. She also said that dd should be able to answer the 'majority' of comprehension questions

That's helpful thank you @findahouse21!

Same as @Findahouse21
Home reading is consolidation.
School reading book in class often next level up

As above. You need 90-95% fluency in order to comprehend.

If it is home reading, it should be for enjoyment primarily and the level doesn't matter IMO.

With phonics books the reading should really be 100% correct.

At our school (daughter just gone into Y1) they read a level lower at home compared to what they read at school.

Home reading is for practice, fluency and comprehension, not for a challenge :)

I’m quite interested in the comments they home reading should be easier. I haven’t found that so far tbh. I’ve found that the books we’ve had home have always included lots of tricky words beyond what they’ve been taught in phonics. I had to look up how to explain the split digraph for example.

When it was all explained to me it was defo that reading at home is practice, consolidation & not to push them. The guided reading in school is for that. Plus 1-1 time to check levels occasionally. Parents shouldn't be trying to teach them etc
