MODELING CYCLE (β˜…)
The basic modeling cycle involves:
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.

Know and be flexible using different properties of operations and objects.
Mathematically proficient students will be able to:
Understand and use stated assumptions, definitions, and previously established results in constructing arguments.
Make conjectures and build a logical progression of statements to explore the truth of their conjectures.
Analyze situations by breaking them into cases, and can recognize and use counterexamples.
Justify their conclusions, communicate them to others, and respond to the arguments of others.
Reason inductively about data, making plausible arguments that take into account the context from which the data arose.
Compare the effectiveness of two plausible arguments, distinguish correct logic or reasoning from that which is flawed, andβ€”if there is a flaw in an argumentβ€”explain
what it is.

Use geometry to solve a design problem or use a function to describe how one quantity of interest depends on another.
Apply what they know and feel comfortable making assumptions and approximations to simplify a complicated situation, realizing that these may need revision later.
Identify important quantities in a practical situation and map their relationships using such tools as diagrams, two-way tables, graphs, flowcharts and formulas.
Analyze relationships mathematically to draw conclusions.
Interpret mathematical results in the context of the situation and reflect on whether the results make sense, possibly improving the model if it has not served its
purpose.

ο‚· Consider the available tools when solving a mathematical problem. 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.
ο‚· Make sound decisions about when each of the tools appropriate for their grade or course might be helpful, recognizing both the insight to be gained and their

limitations. Example: High school students analyze graphs of functions and solutions using a graphing calculator.
Detect possible errors by strategically using estimation and other mathematical knowledge.
Know that technology can enable them to visualize the results of varying assumptions, explore consequences, and compare predictions with data.
Identify relevant external mathematical resources, such as digital content located on a website, and use them to pose or solve problems.
Use technological tools to explore and deepen their understanding of concepts

Mathematically proficient students will be able to:
Communicate precisely to others.
Use clear definitions in discussion with others and in their own reasoning.
State the meaning of the symbols they choose, including using the equal sign consistently and appropriately.
Be careful about specifying units of measure, and labeling axes to clarify the correspondence with quantities in a problem.
Calculate accurately and efficiently, express numerical answers with a degree of precision appropriate for the problem context.
Mathematically proficient students will be able to:
ο‚· Discern a pattern or structure. Example: In the expression x2 + 9x + 14, students can see the 14 as 2 × 7 and the 9 as 2 + 7.
ο‚· Recognize the significance of an existing line in a geometric figure and can use the strategy of drawing an auxiliary line for solving problems. Step back for an overview
and shift perspective.
ο‚· See complicated things, such as some algebraic expressions, as single objects or as being composed of several objects. Example: They can see 5 – 3(x – y)2 as 5
minus a positive number times a square and use that to realize that its value cannot be more than 5 for any real numbers x and y.
Mathematically proficient students will be able to:
ο‚· Notice if calculations are repeated, and look both for general methods and for shortcuts. Example: Noticing the regularity in the way terms cancel when expanding (x1)(x+1),(x-1)(x2+x+1),and(x-1)(x3 +x2+x+1)might lead them to the general formula for the sum of a geometric series.
ο‚· Maintain oversight of the process, while attending to the details as they work to solve a problem.
ο‚· Continually evaluate the reasonableness of their intermediate results.
