Here are two posters that I've created for teachers' classrooms in our district. One gives a description of the SAMR levels, along with "ladder questions" to help get from one level to the next. The other gives subject-area examples of tasks and how they might be adapted for each of the four levels in the model. There are examples for English, Math, Science, and Social Science (adapted from edofict.wikispaces.com), and then a general example (taken from Alice Keeler and Sean O'Neil).
They are both Creative Commons licensed, so feel free to use them in your districts if you find them useful.
