May I be so bold as to suggest my blog? It's incredibly rude, but I'm so excited about what's happening in my own classroom that I want to share these ideas with the world! :) I went to a tech conference with Angela Maiers and she made it clear that EVERY child is a genius. Literally! The criteria for geniuses describes Kindergarteners to a T. Now I say things like "Oh, Emma! I could see your genius today when you were helping Ryan with his math!" The kids just LOVE it, and it's totally true! Angela's mantra is "YOU are a genius and the world NEEDS your contribution!" I'm going to make it a poster to hang in my classroom! I also refer to the kids as Readers and Writers instead of just boys and girls or Mrs. Sigler's class. It gives them ownership of something and they are so proud. How simple but incredibly effective!
