Students use the meaning of fractions, the meanings of multiplication and division, and the relationship between multiplication and division to understand and explain why the procedures for dividing fractions make sense. These practices rest on important processes and proficiencies with longstanding importance in mathematics education. Later, students will see 7 8 equals the well remembered 7 5 7 3, in preparation for learning about the distributive property. As they work to solve a problem, mathematically proficient students maintain oversight of the process, while attending to the details. Mathematically proficient students make sense of quantities and their relationships in problem situations.

They calculate accurately and efficiently, express numerical answers with a degree of precision appropriate for the problem context. Mathematically proficient students are also able to compare the effectiveness of two plausible arguments, distinguish correct logic or reasoning from that which is flawed, andif there is a flaw in an argumentexplain what it is. Thus students expand the scope of problems for which they can use multiplication and division to solve problems, and they connect ratios and fractions. The second are the strands of mathematical proficiency specified in the national research councils report adaptive reasoning, strategic competence, conceptual understanding (comprehension of mathematical concepts, operations and relations), procedural fluency (skill in carrying out procedures flexibly, accurately, efficiently and appropriately), and productive disposition (habitual inclination to see mathematics as sensible, useful, and worthwhile, coupled with a belief in diligence and ones own efficacy). Mathematically proficient students who can apply what they know are comfortable making assumptions and approximations to simplify a complicated situation, realizing that these may need revision later.

When making mathematical models, they know that technology can enable them to visualize the results of varying assumptions, explore consequences, and compare predictions with data. They write expressions and equations that correspond to given situations, evaluate expressions, and use expressions and formulas to solve problems. Students find areas of polygons and surface areas of prisms and pyramids by decomposing them into pieces whose area they can determine. The first of these are the nctm process standards of problem solving, reasoning and proof, communication, representation, and connections. The standards for mathematical content are a balanced combination of procedure and understanding. Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. Such arguments can make sense and be correct, even though they are not generalized or made formal until later grades. Using these methods, students discuss, develop, and justify formulas for areas of triangles and parallelograms. Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace. These tools might include pencil and paper, concrete models, a ruler, a protractor, a calculator, a spreadsheet, a computer algebra system, a statistical package, or dynamic geometry software.
