Was looking at some online maths games for DD, age 7. Stumbled upon this site adaptedmind.com/. Looks like an American one. I was really stunned at some of the problems on there- addition properties, subtraction upto ten thousand... Ye gods!
Tis was on the Grade 2 section. I am assuming it is equivalent to Year 2. If it is, then children here in the UK have quite some catching up to do. Worried now...
