I would like to develop the Plan for Time chapter.  Yes, create time for research, experimentation and discovery between tasks, and even more. A teacher needs to plan for projects with a one or two-week time frame. I ususally use the two weeks time frame, if necessary three weeks. Time allows for practice. It allows students to try it multiple ways, to draft and rewrite and edit. Time allows them to iterate, considered a key-component of creativity, and subsequently, learn. 

For instance in technology, food technology, textiles or arts, any time the students receive a new tool, the teacher gives them time to explore, to play around with it, to work through the platform themselves and thus they are meant to solve problems on their own, using creativity.

The unstructured time in lesson planning will be used for challenging the students, open-time challenges. A certain task, something may be easy the first time and even a second time. When the teacher gives them time to do it in a third or a fourth way, well, that is the moment when the students start to get creative.
