I’ve cross-posted this from my local home ed group (hope no-one minds) as I thought it may interest some of you.  I think my ds would like to go for it.

“The Primary Mathematics Challenge is a national competition consisting of
a test with interesting, mathematical problems (mostly multiple choice) aimed at
the top 60% of 9-11 year olds, although anyone aged 11 or under on 31 August
2012 can enter. I’d say it is suitable for children who enjoy maths and
problem-solving and get bored being tested on whether they can “do”
the basics. There is more information and past papers on the Mathematical
Association’s

website: http://www.m-a.org.uk. Every child taking part will get a certificate, and
Gold, Silver and Bronze certificates will be awarded to those who do
particularly well.

Home-educators cannot enter children directly through the Mathematical

Association so if you would like to enter a home educated child, please join
http://www.groups.yahoo.com/groups/PMC-Home-Ed where there is information about how to
enter.

Last year, 41 home-educated children aged 7-11 took part, 9 of whom reached the
national Finals. It would be great to see even more entries this year!“

A very close friend of mine here is part of the UKMT (UK Maths Trust) and she introduced me to this a few years ago when I was teaching in Year 5.  She leads the group challenges around the UK and set up the ones in the Iberian penisula.  She is also a group leader for the Uk Maths Olympiad team and an already amazing woman.  The Primary challenge and the older children’s maths challenges are really different from the normal QCA style tests (SATs) and the children I taught loved doing them.  They are great for more able children or those who have a real interest in maths.  I would definitely recomment them.  Have fun.
