Help the class visualize operations with complex numbers with a lesson that formally introduces complex numbers and reviews the visualization of complex numbers on the complex plane. The fifth installment of a 32-part series reviews...

Teach how graphic designers can use mathematics to represent three-dimensional movement on a two-dimensional television surface. Pupils use matrices, vectors, and transformations to model rotational movement. Their exploration involves...

Far out — plan a trip to space! Aspiring mathematicians steer a space vehicle through an asteroid field, calculate currency exchanges to buy provisions, and determine placement of charges to blow up asteroids. Along the way, they learn...

Following a catchy video about decomposing numbers, young mathematicians build and write numbers using dice. Class members work to create an anchor chart that displays six ways to make numbers. Beans get scooped and estimated, then...

"Life is more risk management, rather than exclusion of risks." -Walter Wriston. Scholars use provided mortality data to determine how likely it is a person will die from a particular cause. They compare the data to the perception of the...

High school classes can use manipulatives too! Offer hands-on, interactive lessons that venture away from the typical day in your algebra class. Young mathematicians will be involved in collaborative learning, visual...

Earthquakes can be frightening and dangerous, but being prepared can make a world of difference. Perform an earthquake simulation during which the class practices how to drop, cover, and hold on as you read a script...

Develop young mathematicians' ability to compare fractions with investigation into the number 1/2. After brainstorming a list of fractions equivalent to 1/2, children identify a pattern in the numerators and...

Rules are meant to be broken ... but not integer multiplication and division rules. Learners use chips to model integer multiplication and division. The results of the activity help them develop integer rules for these operations.

Discover the science behind astronomy. After reading the book Maria's Comet, which is about a young woman who breaks new ground by becoming a female astronomer, young learners practice reading comprehension with...

Hands-on investigation of Riemann sums becomes possible without intensive arithmetic gymnastics with this interactive lesson plan. Learners manipulate online graphing tools to develop and test theories about right, left, and...

There’s a fine line between a numerator and a denominator. Learners review operations with fractions and ensure they have the skills needed to progress in the course. Taking the time now to review these concepts allows individuals to...

Parallel parking might be difficult, but finding parallel lines is fairly simple. In this lesson, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals then take part...

Sensor technology is amazingly accurate and useful. Combining the sensor technology and mathematical knowledge, scholars design experiments to answer a question they have developed. Questions may focus on light sensing, temperature...

Pupils learn the steps for basic constructions using a straightedge, a compass, and a pencil. Pairs develop the skills to copy a segment and an angle, bisect a segment and an angle, and construct parallel and perpendicular lines.

Geometry gets an engineering treatment in an exercise involving a belt wrapped around two wheels of different dimensions. Along with the wheels, this belt problem connects concepts of right triangles, tangent lines, arc length, and...

It doesn't get simpler than this. Scholars first learn to simplify radicals by determining the prime factors of the radicand. The lesson progresses to simplifying radicals involving algebraic expressions in the radicand.

How do people transport fresh water long distances to ensure everyone has access to it? The final lesson plan in the 10-part Fresh Solutions unit encourages individuals to design their own solution, or solutions, to that very problem....

Pupils discover the equivalence between knots and math through a manipulative exploration. In pairs, they select three sets of identical knots and change their forms without breaking the knots apart. Students pass them along to the next...

students identify and explore the connection between math and the bones of the human body. Students collect data about bones from their classmates and from adults, apply formulas that relate this data to a person's height, and organize...

Students list ingredients, utenstils, and steps in basic chocolate chip recipe. They evaluate the correctness of each list using copy of recipe, measure all liquid and dry ingredients, read recipe and follow steps to make cookies.

Students participate in an online computation game. In this computation lesson, students practice simple computations and use an internet site to review addition and subtraction facts.

Learners research a famous mathematician and create a presentation of their research. For this famous mathematician research lesson, students decide on a famous mathematician that they would like to learn more about. They conduct...

Students play a game to practice concepts and principles that can be adapted to any subject.
