I bought a few Kumon workbooks for my son , and he does a few pages every week and I have to say it has helped him and given him a lot of confidence in Math.
At ESF the kids are taught mental math, so there isn't any working out and he gets the answer wrong by 10 or 100 because problems are written horizontally and not stacked, as we were taught, and he forgets to carry a number over.
So when he does Kumon, I ask him to stack the numbers and add each column.
Have also tried to teach him long division and multiplication which they no longer teach schools.
Kumon also have word problem workbooks which they do in his school, and its good practice for him.
We don't do it daily, just 1 or 2x a week.
There are loads of workbooks and they are reasonable.
