I would like a times tables app for ds1 and the ones I have don't quite do what I want. He knows his 2,10,5 and 3 times tables in order and mixed up.
I'd like an app that I can say which groups I want it to ask mixed up so to start with the ones he knows then add in the next lot he's learnt, just to consolidate his learning.
The apps I've found so far will only mix up either one set of tables or all of them right up to the 12's.
