Language / Help with homework (Polish language learning) (Hurra! Po Polsku - Level 1) [9]

I hope someone can help me, I'm learning Polish (only 6 weeks in at City Lit College in London). I'm trying to tackle a piece of homework for class tomorrow but I simply don't understand it.

I'm really sorry if my understanding is rubbish and I'm not the quickest learner (I do feel kind of stupid right now).

But I'm doing exercise 12b on page 48.

We've started learning about conjugating verbs (cytać/jesć/wiedzieć/mówić/lubić/chodzić/uczyć się/chcieć/pisać/moć/pracować) which I am still trying to get used to in basic forms let along in the conjugated forms.

I'm finding it somewhat difficult to conjugate the verbs...

For example...

On często .................... telewizję (oglądać)
Which I think means "he often watches television".

However I do not know how to conjegate the word "oglądać" properly to make the sentence work correctly.

Normally On/Ona (he/she) has the last letter off of it "mówić" become "mówi" when it is in the context of on/ona. But I know this isn't always the case. So would I be correct in thinking oglądać becomes ogląda??? But when I google it that doesn't seem to be right either.

Can someone give me some help/tips/information on how to nail this. I'm really struggling and I'm getting really stressed about it.
