Progressions for the Common Core State Standards for MathematicsProgressions for the CCSSM: Geometric Measurement in Grades K-5

Description: One of a series of documents describing the progression of a topic across several grade levels, informed both by research on children's development and by the structure of mathematics. In Grade 6, understanding of length-units and spatial structuring comes into play as students learn to plot points in the coordinate plane. In Grade 7, they use their understanding of length and area in learning and using formulas for the circumference and area of circles.
