You can do this if you have nl installed:

ls -1 | nl

(Note with modern shells (ls usually a built-in) the -1 part is not needed. And this applies to the below solutions too.)

Or with awk:

ls -1 | awk '{print NR, $0}'

Or with a single awk command:

awk '{c=1 ; for (f in ARGV) {print c, f ; c++ } }' *

Or with cat:

cat -n <(ls -1)

You can do this by using shell built-in printf in a for loop:

n=0
for i in *; do
   printf "%d.%s\n" $((n++)) "$i"
done
