James H. Schmitz has many great titles for preteens.
The Witches of Karres, Eternal Frontier, Agent of Vega, The Hub: Dangerous Territory, Trigger and Friends, T.N.T:Telzey & Trigger, Telzey Amberdon have all been rereleased by Baen so you can still get them.
Terry Pratchett has several books aimed at preteens.
The Amazing Maurice and His Educated Rodents, The Wee Free Men, A Hat Full of Sky, Wintersmith are all good reads that you may read together with them and enjoy yourself too. That should get a a quick start as all are in print.
The problem with a lot of the classics are you need to get them at used bookstores as many are out of print.
