Consider how we want to handle common misconceptions in our lesson plans and slides

[flannery-denny]

• Currently Common Misconceptions appear in lesson plans as third level headers. Is this optimal? Might strategy boxes be better? Is there an alternative formatting we want to use?
• Currently Common Misconceptions end up in presenter notes. Would it be a better practice to make them visible to students?
• Even if we leave the infrastructure side of things unchanged, let's come to agreement about what voice they are written in. Student or teacher facing?
