Ukelele help?

I am giving my nephew (12) a ukelele for Christmas. I got the tuner, it is prestrung has a case and I got a couple of pics.

However, I was thinking I should round it off with an easy guide. So I am vying between two to three different learning styles:

For guitars a lot of beginners use tabs or YouTube. However he has limited internet time, and I am not certain ukulele’s have tabs.

He does play clarinet a little so he does have very basic musical knowledge, I do think schools cut it a little thin on music theory, which is so helpful in learning multiple instruments.

But then he really loves pop and country, I know… Not the best start, but at least he loves music, if he has to start out with Ode to Joy and Twinkle Twinkle I don’t know if he will stick with it.

So I don’t know if he will love this or not. I was approaching it from an angle of start on a ukelele move up to guitar and at least learn a handful of songs to pull out to impress girlfriends..

He’s the creative arty nerdy guy he will need the help in high school. Besides he loves hands on things so this seems like a good outlet.

So which direction should I go and bonus for any sources.
