Sequenced Units 3 rd Grade – Rutherford Co. Allison Ragan & Marrie Lasater
Session Goals The focus for third grade level will be emphasized. The importance of Table #2 from the CCSSM document will be stressed. The Dana Center Sequenced Units will be explained. Participants will understand the need for number sense and see fluency in a new light. Line plots, rectilinear, and distributive property lessons will be shared. Use TNCore Task Arcs as resources.
CCSS, Introduction In Grade 3, instructional time should focus on four critical areas: (1) developing understanding of multiplication and division and strategies for multiplication and division within 100; (2) developing understanding of fractions, especially unit fractions (fractions with numerator 1); (3) developing understanding of the structure of rectangular arrays and of area; and (4) describing and analyzing two-dimensional shapes.
3 rd Grade Focus Clusters OA clusters A and B from Number and Operation Fractions - Fractions on a number line; equivalent fractions; whole numbers as fractions; and comparing fractions with the same numerator or denominator Measurement and Data (C) – Area including rectilinear

Fluency For a long time it was believed that children learned their basic facts through drill and memorization. However, now psychologists and mathematics educators believe that developing quick and accurate recall with basic facts is a developmental process that depends on the development of reasoning strategies. (Teaching Student-Centered Mathematics Van de Walle, Lovin, Karp, and Bay- Williams)
