All the direction you need to do this on this thread.
But here’s some help:
First make a child theme:
If you haven’t made any direct changes to any of the theme files
you can make a child theme by:
create a folder called:
beanstwentyten
in that folder place a style.css file that says:
/*
Theme Name: Beans Twenty Ten
Description: Child theme of the Twenty Ten theme
Author:
Template: twentyten
*/
@import url(“../twentyten/style.css”);
Now upload (ftp) or (Cpanel) this folder to your wp-content/themes directory
Then go to Appearence — themes- and activate it
Now you have a child theme.
—————————————-
The directions below can now be carried out in the child theme.
This is what the front-page.php template could look like with the code to pull your latest (1) blog post to the front.

You will need to adjust the css styles to make it look pretty.
(You would upload this template to wp-content/themes/beanstwentyten)
Now you set : Static — home
You Create the Home Page in the editor (if you are calling your current static page home page)
then Open it in the editor and
change the template from default to the new front-page.php template (on the right sidebar of the edit pane)
Now you should have a static front that looks just like your current static front with a post link and excerpt below. (you will have to make the css to make it look like you want)
————————– If you don’t make a child theme—-
The big caveat to this is that you never created a child theme and your are editing TwentyTen directly.
I urge you to take a back up of the theme folder every time you make a change to it.
(FTP — download theme folder) After every tweak… all it may all be over written
