Students explore how to derive pi (∏) as a ratio. Students also study the circumference and area of a circle using formulas.




1163


Students will investigate relationships between sides of right triangles to understand the Pythagorean theorem and then use it to solve problems. Students will simplify expressions using radicals and exponents in this activity.




789


Students who are familiar with the two most common standards of measuring temperature learn how to reliably convert from degrees Celsius to degrees Fahrenheit. Students also see how order of operations is crucial in an equation, through discussion and data entry on the calculator.




371


Students will be introduced to the different ways to calculate numbers of outcomes, including using the counting principle. They will also evaluate expressions using permutations of data without repeat elements, both manually and on the TI30XS MultiView™ calculator.




340


Students who understand the basic concept of square roots learn how to evaluate expressions and equations that have rational and irrational solutions. Students also explore solutions to equations and investigate the differences between exact and approximate solutions using the calculator.




654


Students will see how fractions, decimals, and percents are interrelated, then explore and learn how to convert between them. Students will also practice estimating.




463


Students will explore standard and scientific notation representations of numbers. Students will also discuss the need for different representations of very large or small numbers, and they will see realworld examples of these representations.




468


Students will use a physical model to determine what happens when they repeatedly halve a piece of paper, and then they reassemble the pieces into a whole. They then use an algebraic model to analyze the same situation, which leads to an introductory discussion of limits.




297


Students will analyze select nutritional values of specific food products and then compare those values to the recommended daily allowances published by the U.S.D.A. They will calculate percentages and fractions based upon the information they find.




333


Students divide and multiply mixed numbers and fractions in reallife examples relating to carpentry.




617


Students will compute multiples of numbers in search of patterns. As a class, they'll discover patterns in multiples of 9; then they'll do the same with patterns in multiples of 11. They will then practice writing the rule for 11, both verbally and algebraically, to summarize the discovered pattern.




332


Students use linear equations to model and solve realworld problems. Students also see the correlation between the graph of an equation and its calculated slope by plotting graphs by hand and then calculating slopes with the calculator and comparing.




378


Students will compare two cell phone plans and determine which plan is better for a specific situation. They will utilize both tables and graphs to make their decisions. Students need prior experience writing linear models for this activity.




419


Students learn/review some of the different measures of statistics and see how to use those measures to analyze a data set. Students also participate in a discussion about how statistics can be used to achieve a variety of results.




352


Students will estimate the heights of various celebrities in inches. They will convert inches to feet, and they will interpret the calculator results to express the estimated heights in feet and inches. Finally, they will graph the estimated heights and actual heights of the celebrities.
