Learners find the area of a region between two curves. They integrate functions such as sin(x) and cos(x) on a given interval and find the area bounded by the two functions. Pupils use their TI-89 to aid them in finding the bounded...

Students explore the concept of rounding. In this rounding lesson, students round fractions and mixed numbers. Students estimate the sums, differences, products, and quotients of rounded fractions and mixed numbers.

Leanrers observe models of fractions and use a calculator to represent numbers as decimals, fractions, and percents. They participate in calculator activities to view different representations of the same number.

Pupils investigate the formulas for volumes of various solids using the Ti-89 calculator. The instructional activity focuses on the keying sequences necessary to embed the required volume formula in a program which is then used in the...

Learners perform factoring on the TI. In this algebra lesson plan, students factor equations using the FOIL method. They use the TI navigator to show each step using a visual.

Students identify different parts of a triangle. In this geometry lesson, students differentiate between similar and congruent triangles. They use the navigator to crate a visual of the different parts of a triangle.

Learners study weather using a graphing calculator in this lesson. They collect data for temperature and relative humidity for every hour over a day from the newspaper, then place the data in their handheld calculator and examine it for...

Students differentiate between linear and quadratic functions. In this algebra lesson, students write equations of graphs and graph a function from an equation. They also identify the slope and y-intercept.

Learners analyze linear functions in this algebra lesson. They explore the meaning of slope and the slope-intercept form of a line as they investigate the effect changing parameters on the graph of a linear function.

Pupils investigate financial applications of mathematics in this mathematics lesson. They will investigate equations that represent a company’s income, expense, and profit functions and use those equations to identify break even points...

Young scholars explore an application of differentiation in this calculus lesson. They investigate the ideal dimensions for a soda can and, using the symbolic capacity of the Ti-89, investigate the dimensions of the can which has the...
