Their template is very easy to understand, but to read more see How do you plan? On templates and instructional planning and How do you plan? redux by Grant Wiggins.

There is a useful template for Understanding by Design available at How do you plan? redux. Just scroll to the bottom and look for DG.UbD_TemplateV2_OnePg
