Well... I had my Tattle Box for the last two years, and it had a lot of success! I was so excited to spice it up this year and created a monster out of the box... and then I saw that Mariah at Giggles Galore had already posted a "Tattle Monster". Although this was my own original idea, I still want to give her credit since she posted first. So, be sure to check out her blog!!
This can easily be made out of a Kleenex box. Just cover it in paper like a present and decorate :) You could even have the students decorate it. I always have a pencil and notepad ready for the students. This is great because students are getting extra writing practice and leaving you with a little extra time... and some sanity haha.
