Math Committee October 15, 2009 Math Activity Figure out the weight of each shape in the mobile in figure 1. The total weight is 24 units. CHALLENGE: Could the mobile still work if there were 3 objects on one side and four on the other? Draw a picture and check your thinking. NCTM – Teaching Children Mathematics, March 2009 NCSD Math Beliefs Blue: Mentioned on committee’s feedback—already in beliefs. Red: New idea added, based on committee’s feedback. Drilling into the Core Standards Select one Core Standard from your grade level. 4.2 Number and Operations and Algebra: Develop fluency with multiplication facts and related division facts, and with multi-digit whole number multiplication. Identify a Content Standard within that Core Standard to guide your work. 4.2.1 Apply with fluency multiplication facts to 10 times 10 and related division facts. 4.2.2 Apply understanding of models for multiplication (e.g., equalsized groups, arrays, area models, equal intervals on the number line), place value, and properties of operations (commutative, associative, and distributive).

Mathematical proficiency for the 21st century is best defined as an interdependent balance. Adding It Up National Council of Mathematics, page 116 Five Strands of Mathematical Proficiency Conceptual Understanding: comprehension of mathematical concepts, operations, and relations. Procedural Fluency: skill in carrying out procedures flexibly, accurately, efficiently, and Appropriately. Strategic Competence: ability to formulate, represent, and solve mathematical problems, often finding more than one path to a solution. Adaptive Reasoning: capacity for logical thought, reflection, explanation, and justification. Productive Disposition: habitual inclination to see mathematics as sensible, useful, and worthwhile, coupled with a belief in diligence, and one’s own efficacy.
