The first vowel in Hiragana is あ. Pronounced as "ah". Like the "a" in "car" or in "awful". Underneath is the correct stroke order for when writing it. Stroke order is actually very important! It helps the symbol come out nicer, and Japanese people will comment if you don't write it in the correct order or may not be able to read it at all. Horizontal lines are first and then it goes top to bottom and left to right. It takes a bit of practice but after awhile the stroke order will become like second nature :)
がんばって～！ Good luck~!
