As a pre-school teacher I was always counting something. If you child puts on a button down shirt, count the buttons as you do/undo them.
The grocery store is a great place to do letters and numbers. Have your DD count out cans of peas, tell her to give you 3 cans of peas and have her count out loud, then spell the word P-E-A-S or ask her what the first letter or last letter is. This also teaches sequencing.
Count pennies, buttons (loose), flowers, legos, make your own flash cards. A piece of poster board is .50 from the Dollar Tree. Make a matching game or just throw between 5-10 letters on the ground and have her step on the letter A, now step to the letter B, you can do the same with numbers and have her walk from 1 to 10 around the room. This way she is moving and interacting with you and the bonus is she is learning without even realizing it.
Also google learning letters and numbers and see how many responses you get. you'll be amazed.
The main thing is to keep it fun, If she is getting frustrated step back for a bit and do something else.
Not too far east from Mt Rushmore in Wyoming is a Place Called Devil's Tower. It was a lets just go check it out on our vacation and it ended up being one of the favorite places we saw. On the way to Devil's Tower we saw a advertisement for a Buffalo run that had reciently been discovered. If you had the energy you could hike all the way down see the layers of buffalo bones. IT was really neat. I think they were supposed to be getting funding on on making it kind of like a museum. This was around 2001 so don't know what has happened to it since. ... View related article.
