Children present a song using sign language - tips needed

[Arnold]

Hello everyone!

I'm a primary school teacher in Thailand. My 2nd grade kids are preparing a show for parents day where they will sing a song (sing - carpenters) and present it in sign language.

I already have most of the words from Signing Savvy | ASL Sign Language Video Dictionary but have no idea about whether I should use words like "of" "the" etc.
I understand that the words "sing" and "song" have the same sign. Is that right?

The plan is to make a video and teach the kids everyday.

I'll be very happy for some tips of which words should I choose. and any general tips and pointers on what to do and how.

Thanks,
Arnold.
