Ellie, my DD is in Y1 now, but at the end of Reception, what they were expected to be able to do was roughly:
Have a decent handle on numbers up to about 20 - be able to count objects and do one more and less or maybe do up to 10 more and less if a bit more at home with numbers. Some children were doubling and halving numbers; using physical objects as a prop is fine.
Know 2D shapes and be starting to know 3D shapes. Be able to point out why a triangle is a triangle etc (3 sides, 3 corners etc).
Be able to read common words (they, are, you etc) or easy words, probably using sounding out to read the less familiar ones rather than being able to read them all immediately. More able children might have been reading harder words or less common words and would be expected to be letting go of sounding them all out. They would know all the basic phonic sounds of the English language and be able to put them together at a fairly basic level.
Be able to make a good and phonetically plausible stab at writing words - no more than a sentence or so at a time would have been expected, though some children would have been at the stage of producing several sentences and using capital letters and full stops.
They'll have done a bit of topic work, perhaps some science along the lines of using cups of water/sand to fill up other vessels and seeing how many cups you can fit into this jug or similar. Maybe some nature study along the lines of going to the park and looking at leaves - common features of leaves, what colours leaves can be, what happens to leaves in autumn, what insects can we find and what are they like - can you draw them etc. Maybe biology - DD's class had chicks hatching and talked about the life cycle of a chicken and had butterflies hatching so talked about those too.
They will have done some history or social studies - perhaps talking about what was different when their parents and grandparents were young and asking family members about that, or investigated some common celebrations in the UK - Christmas, Diwali, Eid, Easter, Bonfire Night etc and talked about traditions that different people have. They might have talked about families - who is in their families and drawn pictures of people who are special to them etc.
Your daughter sounds like she is doing fine. At the end of Reception there is a huge variation in how far children have got with academic stuff and it is not necessarily related to how well they will ultimately do in their studies - right now in Y1 my daughter's mixed Y1/2 class has children on ORT Red and children who are off the reading scheme entirely. There are children who are working on one more and one less and children who are learning about multiplication and division at a simple level. There are children who will happily sit down and write a page of A4 which is nearly all spelt correctly and children who struggle to write a few words in a sensible order.
It sounds like your daughter is currently somewhere in the middle of that range and as she is still in Reception, she is doing just fine and will probably fit in perfectly well to any Y1 class.
