I am a tutor

I had a group of teenagers to whom I gave them taught some classes about in religion, healthy habits and adolescence. also I've also spent time teaching to children math and some basic words in English.

I think the poster aboveis confused when she says that math is written maths in the US and Canada. I have never heard anyone in the US call mathematics "Maths", and I have several Canadian friends that do not call it "maths" either. This would certainly be incorrect.

More correct:

I gave some classes on religion, healthy habits and adolescence to a group of teenagers. I have also spent time teaching children math and some basic words in English.

<em>Note that in the UK mathematics is written "math" and in the US and Canada mathemtaics is written "maths" - both are correct, it just depends where you are based and who you are teaching or writting to.</em>
