If you're a home-schooling parent, or if you just want to encourage your kids to practise the German they're learning at school, these sites will help.
The UK TV channel, Channel Four has collaborated with the Scottish government to produce Hennings Haus, a series of interactive activities aimed at children between 9 and 12. However, each activity is offered at three different levels, and slightly younger children who had been learning for a while could easily cope with the lowest level. Hennings Haus is also a TV series - the programmes are shown during the night and can be videoed for later use. If you're in the UK, check here for the schedule, or - again for UK residents - check them out on Teachers' TV. Otherwise the programmes are also available on DVD/CDRom. Check out the Channel Four site for other information, and also the programme transcripts.
The Prescott School's Primary German site contains some fun activities on vocabulary topics such as animals, colours, numbers, the family and the names of days and months. A pity that the spelling of the English instructions is so appalling. This was written by teachers?? Two stars.
If you're homeschooling, the Primary Resources site has a large number of resources - worksheets in Word or PDF, Powerpoint presentations etc to help you organise your child's German course.
