We just got this email. English state funded Primary schools get free access to 10ticks maths resources! Visit: 10ticks.com/liontrust (mental maths) and 10ticks.co.uk/liontrust (worksheets inc White Rose mapping). Thanks go to Liontrust for delivering this to all English Primary Schools. Anyone else signed up?
The worksheets site is worksheets, but lots of different types - lots of games puzzles etc, so worth getting just for that. From the little I know of sumdog it is very game orientated, where it seems to have games with maths. This is mainly focussing the questions themselves - our pupils like playing against the class and getting on the high score .. try it with one class and then decide.
