DS1 hasn't done any algebra at school. He's working through Nelson 10 min-tests to expose any weak points.
He managed to work out the algebra questions through logic and guess-work, but was a bit on the slow side.
Do you think I need to teach him algebra, or not?
(I've always been reluctant to encourage him with any Maths at home, because I think they then quickly get so bored at school if they are ahead in Maths.)
