6. High School MathematicsConceptual Category: Modeling Examples: • Estimating how much water and food is needed for emergency relief in a devastated city of 3 million people, and how it might be distributed. • Planning a table tennis tournament for 7 players at a club with 4 tables, where each player plays against each other player. • Designing a layout of the stalls in a school fair so as to raise as much money as possible. • Analyzing stopping distance for a car. • Modeling savings account balance, bacterial colony growth, or investment growth. • Engaging in critical path analysis, e.g., applied to turnaround of an aircraft at an airport. • Analyzing risk in situations such as extreme sports, pandemics, and terrorism. • Relating population statistics to individual predictions. The basic modeling cycle is: (1) identifying variables in the situation and selecting those that represent essential features, (2) formulating a model by creating and selecting geometric, graphical, tabular, algebraic, or statistical representations that describe relationships between the variables, (3) analyzing and performing operations on these relationships to draw conclusions, (4) interpreting the results of the mathematics in terms of the original situation, (5) validating the conclusions by comparing them with the situation, and then either improving the model or, if it is acceptable, (6) reporting on the conclusions and the reasoning behind them. Choices, assumptions, and approximations are present throughout this cycle.

10. Key CCSS Summary These Standards are not intended to be new names for old ways of doing business. They are a call to take the next step. It is time for states to work together to build on lessons learned from two decades of standards based reforms. It is time to recognize that standards are not just promises to our children, but promises we intend to keep. (page 5)

11. 1 Make sense of problems and persevere in solving them. • Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. • They analyze givens, constraints, relationships, and goals. • They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. • They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. … more

12. They monitor and evaluate their progress and change course if necessary. • Older students might, depending on the context of the problem, transform algebraic expressions or change the viewing window on their graphing calculator to get the information they need. • Mathematically proficient students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends. … more

13. • Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. • Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, “Does this make sense?” • They can understand the approaches of others to solving complex problems and identify correspondences between different approaches. !!

14. Challenge Consider the Olympic data set, and the research question: Will women ever run faster than men in the 200-meter race, and if yes, when? Design a task (lesson) that involves the above data and question. Include in the task connections to a conceptual category, cluster and important standards. More importantly for our current discussion, connect the task Practice #1.
