Camera

Another one of those which i remember doing when i was a child. Kids usually like this little paper toy. The 'photos' are drawings drawn on a number of small papers.

Fortune teller (cootie-catcher)

A fun 'fortune-teller'. Children like this game. Slide your fingers and thumb under the four flaps. The fortune-teller moves in and out by moving the index finger and the thumb.

I think it was my brother who taught me to fold this when i was a child. Simple and easy to fold.

Boat

I learnt to fold this as a child. It is a very simple design and a good start to introduce a child to paper folding. If folded with a sturdy paper, it should float on water.
