The book seller came to school and I got this cool battery operated candle light that glows different colors! I decided to use this in my room as a visual cue to the kiddos who consistently interrupt reading groups when there are other adults in the room who can answer their questions! I love it and it has worked fabulously! I've even heard a student say...the light is red, you have to wait! It has really reduced the amount of questions during this limited time and allows the kiddos to problem solve!
