Unit plans (or the like) for Year 7 Numeracy

[NoWittyName]

Hi,
I'm a primary trained teacher who is presently teaching numeracy across several year groups.
We have two children who have stayed with us who are in year 7. I am not at all worried about teaching year 7, but would like to know I am teaching the correct thing! Where can I find something that tells me what I should be covering? I have looked in the web, but it is difficult to find a definitive list of objectives in the same way you can find unit plans for KS1 and KS2.
We are expecting Ofsted this year, so don't want to be caught out. Any help or advice would be GREATLY appreciated.
Thanks
