Differentiation Modifications The Three Questions Explanation Checklist on the back of the Three Questions Handout can be used to scaffold students’ explanations in many ways. Students refer to the checklist as they are constructing their explanations. Students use the checklist as they are sharing and revising their explanations with a partner. Students use the checklist to critique and revise their final explanations. Students use the checklist to critique the example explanations for each unit. Students use the checklist to create and/or evaluate a whole-class consensus explanation. We recommend using this checklist with a gradual release. As students improve in their ability to write their own explanations, they may rely on the checklist less.
