5 Use appropriate tools strategicany

Mathematically proficient students consider the available twis when sdvülg a mathematical problem. These tods might nclude pend and concrete models, a ruler, a protractor, a caculator. a spreadsheet. a computer system, a statistical cnamic geometry software. Proficient students Me sufficiently familiar with tools appropriate for their grade or course to make sound d«isions about when each Of these might
be helpful. the insight to be gained and their limitations. For example. mathematically proficient high school students analyze graphs of functions and solutions generated using a graphing They detect possble errors by using estimation and other mathematical knowledw When making mathematical models. they know that cm enaNe them to visualize the results Of varying assumptions. explore
consequences. and compare with data. Mathematically proficient students at various grade levels Me able to relevant external mathematical resources, such as digital content on a website, and use them to pose or solve problems. They are able to use techno@cal tcx.ls to explore and their understanding of concepts

 Mathematically proficient students try to communicate prKisety to others. They try to use clear definitions dscussion with others and in their own reasming. They state the meaning of the symbols they induding usmg the equal sign consistently and They are careful about units Of measure. and axes to clarify the correspondence with quantities in a problem. They calculate and efficiently,
express numera answers with a degree of precision appropriate for the problem In the elementary students give carefully formulated explanations to each other By the time they reach high schc they have
learned to examine dams and make explicit use of definitions

How are real-worw situatims involving that grow or dedine rapidly mathematicdly? Sample answer: Quantities that rapidy are modeled by exponential yowth functions, and quantities that dedine rapidly are by exponential functions

What Will You Learn

Texh Have students rne and one of their Foldable for every two lessons in the module and use the appropriate as they cover the material Have students list the Key Cmcepts and the terms and their in their Foldable. Point out that the Foldable can also be used to positive and negative
experiences durülg learning

When to Use It Encourage students to add to their Foldable as they. work throu$ the module and to use them to review for the module test
