One practice that I want to use more consistently is formative assessment. These may often be seen in the form of 'exit tickets,' but can also be integrated into the lesson as part of a transition, or closure to a topic. It is really important to have students reflect on their own learning, and to get a 'pulse' of the class frequently, and long before a unit test. By then it is really too late.
In many cases administrators are looking for closure and student reflection when they observe your class. Exit tickets or formative assessment are a great way to do that.
Below is a four pack freebie of four exit tickets that I frequently use in my classroom. They are downloadable as a pdf file, and print four to a page. They are set to print four to a page. Here is the link. Enjoy!
These are a sample of a larger pack of 50 (!) Exit tickets
