There is a planning sheet that is recommended to use with this. It can be found here: https://www.teacherspayteachers.com/Product/FREEBIE-City-of-Ember-Writing-Planning-sheet-1853433
Students can share their writing ideas, and this will "spark" their interest for "People of Sparks". They love knowing if any thing they wrote happens in the new book!
My 2nd graders have loved doing this!
