I use this with my maths class as we stream our maths classes at my school and needed something for behaviour management. I use it with the free website class dojo! It does not cost me anything which is why I love it. It also rewards the positive and the student who always work hard in my classes, while helping to motivate the students who find it hard to stay on task.
I have left it in a word format so you can edit it to suit you.
Hope you like it.
