DD left pre-school with a pretty good understanding of numbers for her age - could count things, add things if she had two groups of things and could do "one more than" for numbers up to 10. I don't think her maths improved at all in reception, except she learnt to reliably write numbers. I mentioned this to her teacher who said not to worry - she thought she actually had an aptitude for maths and it would just come in time. Roll on to year one, and I've been told she's falling badly behind in maths. She still can't add numbers together up to 10 without counting something (e.g. groups of beads). She apparently struggles with the basic concepts and needs a lot of support. In addition I've noticed she's actually having trouble writing numbers (which she used to be fine at) - they're often back to front.
I need to go back and get some ideas of how I can support her better at home, but was wondering if anyone had any ideas? I just find it so strange that she seemed to start out fine, but is not making progress or "getting it". Her reading is very good, and everyone says she seems bright, but for some reason not reaching her potential.
