These are the Amazing Words for Unit 2 in Scott Foresman's Reading Street for 1st grade. I put these on my board each week and introduce a few daily (as is indicated in the curriculum). I have my students raise up one hand of "spirit fingers" very quickly whenever they hear me or anyone else say the word. They only see one week's words at a time but remember these words all year and get so excited when they can use them or just hear them being used. I also use some of them as challenge spelling words for my super spellers!! I have a polka-dotted Peanuts themed classroom so these go perfectly and would easily blend into any theme.
