Excerpt 7: Operations & Algebraic Thinking in Grade 2 (Pages 18-19)

Progressions for the Common Core State Standards for MathematicsDraft K Progression on Counting & Cardinality and K-5 Progression on Operations & Algebraic Thinking

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. Grade 2 students build upon their work in Grade 1 in two major ways. They represent and solve situational problems of all. Because some Grade 2 students are still developing proficiency with the most difficult subtypes, two-step problems should not involve these subtypes. Most work with two-step problems should involve single-digit addends.
