Hi Simbapride:
I'm just a Mum - but information flow at our school was initially quite poor (things improved radically in the run up to OFSTED inspection).
It sounds like what you want to understand is what will be covered for that entire year. If so - can I suggest the following:
Campaign for Real Education has prepared statements on what should be covered for each year (age group): www.cre.org.uk/primary_contents.html - just select the curriculum you are interested in getting details on. Please do bear in mind that this is 'ideal world' stuff - and may well exceed what your own school is aiming for. As a parent I find this an incredibly useful yard stick against which to form expectations on what my DDs should be covering or not.
Ask around - I also find it incredibly interesting to hear from other parents what they're kids are doing. Whilst you're waiting for your child at lessons or pick up time at a club, etc... - strike up conversations with other parents and ask them about what their DCs are doing in school right now. It really helped me to get the confidence to feel our school was 'coasting' a bit - and could be doing more.
If you feel your DS could do with more materials - worksheets/ games - to give him opportunities to reinforce and practice what is covered in Y2. Can I suggest you go to BBC Learning - but enter through Schools/ Teachers (boxes on right hand side of web page) and then you can select the area of curriculum you are interested in - www.bbc.co.uk/schools/teachers/ - in the middle left there is an orange box - select the KS1 tab and then select the subject.
When you click the subject - you go onto another webpage with a blue box and some areas to chose of this curriculum topic to chose from. You can use these and explore (usually on-line games) or to the right you can click subjects under the KS1 subject list and you can then have access to worksheets, activities or games.
Also don't forget BBC Bitesize which reviews English, Maths and Science for KS1 SATs. www.bbc.co.uk/bitesize/ks1/. This is ideal review and very useful - in that if your DS struggles you know there's a lot of catch up work to be done. The nice thing about Bitesize is that the games are pretty easy to run, so once they've started you can get on with cooking, your own work, etc...
Obviously all schools and teachers are different, but I didn't met with much help when my DD1 was seriously struggling in a number of areas in Y2 - so have found it easier to search out this kind of information and generate ideas of things we can do at home myself, rather than get it from our school.
