Also the d'Aulaire books on George Washington and Benjamin Franklin.
There's a magic tree house book on the subject.
Felicity, from the American Girl series grows up in Colonial Times. :-)
There's a Diane Stanley book (she's so awesome) called Joining the Boston Tea Party
"The Courage of Sarah Noble" is a good one for younger kids.
I have a bunch of ideas from the Sonlight Curriculum. I usually just use what I can pull from the library and I haven't checked on that yet. But here's what Sonlight uses for American History:
American Adventures 1 - Greenberg SL3 (many topics 1770-1870)
The Story of the USA: A Young Nation Solves Its Problems - Escher SL3
Pocahontas and the Strangers - Bulla SL3
Squanto, Friend of Pilgrims - Bulla SL3
What's the Big Idea, Ben Franklin? - Fritz SL3
Ben Franklin of Old Philadelphia - Cousins SL3
Mr. Revere and I - Lawson SL3
And then What Happened, Paul Revere? - Fritz SL3
Can't You Make Them Behave, King George - Fritz SL3
Johnny Tremain - Forbes SL3 (American Revolution)
Toliver's Secret - Brady SL3 (American Revolution)
Phoebe the Spy - Griffin SL3 (American Revolution)
Martha Washington (Childhood of Famous Americans) SL3
Meet George Washington - Heilbroner SL3
George Washington (Childhood of Famous Americans) SL3
Winter at Valley Forge - Knight SL3 (1777)
If You Were There When They Signed the Constitution - Levy SL3
Meet Thomas Jefferson - Barrett SL3
Diary of an Early American Boy - Sloane SL4 (1805 pioneer life)
Johnny Appleseed - Kellogg SLK
Ben and Me - Lawson SL2 (Ben Franklin)
I'm sorry if those aren't helpful for a five year old. These are mainly for my eight year old daughter. The SL3 means it's Sonlight's level 3.
A long time ago I read a fabulous book called "The Signers: the 56 Stories behind the Declaration of Independence". It's not a read aloud for young kids but it was FABULOUS and I told the kids the stories in my own words. Many of the stories moved me to tears as I told my children about the courage of the men who signed the Declaration of Independence.
