5 ukulele chords for a beginner to learn

This will be a two part-er specifically geared at all you beginners that are just picking up the ukulele.  In this first part, we'll cover 5 basic chords that I consider to be the most vital "first" chords to learn. Here's part two where we cover 5 beginner songs that use these 5 chords.

I sometimes contemplate what I would do differently if I had a Delorean and I could travel back in time to when I first started playing the ukulele....of course, I would also need a flux capacitor, but anyway....

One of things that I keep coming back to is what chords I would have chosen to learn at the beginning of my ukulele journey.  As I thought about this, I narrowed it down to 5 chords that I believe are most important and essential for a beginner to build around.  It's my hope that these 5 basic chords will be a good foundation
