This is a lesson/assessment resource. It addresses CCSS 7.G.1 and 7.G.6. It is useful as there are detailed lesson plans, student handouts, assessments ppt and error analysis recommendations, questions to ask students to lead them to a solution. I like how students work together to analyze sample responses and justify their own solutions.
