(first post from my iPhone so we shall see what it looks like hmmm)
I wanted to share this idea (evolved from Elements of Reading Vocabulary -love it). It really helps my kids understand new vocab.
Each day I give each student a chance to share. "Do I have any Word Catchers today?". Their hands shoot up. When they share, they have to tell me when/where they hear/saw the word and give the word in the context in which they encountered it. This is how I keep record. You can even make it into a competition with groups or teams. And when I hear a student using a word (or past word) I give them a reward.
