Roses are red, but did you know that some are lighter while others are darker? Scholars read an infographic to decipher the fraction and percent of rose color and their country of origin. They go on to make comparisons and estimate while...

In this algebra worksheet, students match the currency with the country of origin. They convert between that currency and the US using a foreign exchange conversion table. There are 35 questions.

What starts as a basic question of division and remainders quickly turns abstract in this question of related ratios and radii. The class works to surround a central coin with coins of the same and different values, then develops a...

High schoolers, with the assistance of their TI-84 Plus / TI-83 Plus calculators, explore and assess the connections between an accumulation function, one defined by a definite integral, and the integrand. They summarize that the...

Students investigate the currencies used by different countries, and explore the principles of currency trading by exchanging currencies at current market rates. They, in groups, access websites which give them current rates.

High schoolers investigate parallel and perpendicular lines. They use Cabri Jr. to construct and explore the relationships between the slopes of parallel and perpendicular lines. The drawing and measurement tools available with Cabri Jr....

Students calculate and graph the costs of essential items needed in Kosovar refugee camps on an individual, family, and camp basis. Additionally, students explore how relief organizations and businesses participate in relief efforts.

Algebra learners look at equivalent expressions in the context of three different operations: division, squaring, and absolute value.  In comparing these values, they will identity when expressions are equivalent. 

Exponential growth is modeled by learners as they analyze and interpret the data presented in this real-life scenario centered on the destructive invasion of the Giant African Land Snail. Learners get a touch of history and practice...

Fifth graders apply the symmetry and angle properties of polygons and use fractions to express the relationships between the areas of rectangles, squares, and triangles. They analyze various country flags and develop mathematical...

Solve problems using the fundamental theorem. In this calculus instructional activity, students solve problems using theorems and proving theorems. They derive the fundamental theorem as they study it.

Eleventh graders research quality of life indicators for a list of countries looking at such things as infant mortality rate, and gross domestic product. They rank the countries from best to worst regarding quality of life issues.

What does it mean for something to grow exponentially, and how does that compare to linear growth? This activity tries to help learners gain an understanding of these concepts while modeling real-world problems. Linear and exponential...

Students examine the economic effects of a strong and weak U.S. dollar. They identify the currency used in countries which regularly trade with the U.S., discuss the pros and cons of a strong U.S. dollar, and calculate the prices in...

Students recognize how international trade affects them as consumers and become familiar with basic agricultural crops grown in Kentucky. They identify items used in their daily lives and .heir place of origin and examine export/import...

Students read a story. In this telling time lesson, students complete a worksheet where they must practice their knowledge of telling time. Students read a fable and answer time questions as they read.

Students explore the poinsettia and its symbolism as a Christmas flower. Students will listen to a story about the poinsettia and its origins in Mexico and discuss what they know about Mexico. They will discuss the poinsettia's...

Common Core mathematical practices require that young mathematicians not only know how to add fractions with unlike denominators, but also to recognize when adding fractions are appropriate for the word problem. Fifth graders are given...

Math whizzes explore dilations. They use matrices to perform dilations centered at the origins of triangles and investigate the effect of scale factor on the size relationship between the pre-image and the image of a polygon. A link to...

Learners practice generating parabolas with a motion sensor while determining the vertex form of the equation. They compare it to the regression equation from the calculator onto a data mate software. Each student completes several...

High schoolers explore algebraic expressions in this Algebra I lesson. They evaluate expressions using paper and pencil and then use the TI-83 to provide immediate reinforcements.

Challenge young mathematicians to buy classroom supplies by staying within the means of a $1,000 budget. The mathematical activity provides learners with the opportunity to decide what items from the supply list would benefit a class of...

Examine dilation with matrices with your class. Learners write a conjecture for how the scale factor determines the size of an image. They then use their conjecture to write a matrix multiplication problem for the illustrated...

Food takes a trip to the table. Class members choose a meal from a menu and calculate the total cost of the meal including tax and tip. Using a food origin card, pupils determine how far each of the ingredients of a meal traveled to end...
