iBoard first caught my eye last year at the BETT exhibition. They produce an excellent bank of interactive resources for Reception, Year 1 and Year 2 classes in several subjects, including literacy, numeracy and science.
Since then, iBoard has been purchased by the Times Educational Supplement (TES) and made available free of charge to all teachers, which is an excellent development.
You can access the resources here: http://www.tes.iboard.co.uk/
Thanks to James Hollis for reminding me of this excellent resource!
