Working with imaginary numbers — this is where it gets complex! After exploring the graph of complex numbers, learners simplify them using addition, subtraction, and multiplication. 

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

Place a lesson on sequences in your sequence of lessons. Scholars first learn the basics of geometric sequences, such as common ratios and then they write recursive and explicit formulas for geometric sequences.

The title says it all: Could King Kong exist? Investigate how increasing the dimensions of an object affects its surface area and volume to mathematically conclude whether a creature with the weight and height of King Kong could actually...

How much does your class know about the Jewish Festival of Lights? Young learners practice Hanukkah vocabulary, including latkes, Judea, sufganiot, and gimel, in a series of word puzzles.

Don't throw away those transparency sheets just yet! Young scholars first review inequalities on a number line, then learn about graphing inequalities in the coordinate plane. Finally, they use overhead transparencies to create systems...

Class members perform complex operations on a plane in the 17th segment in the 32-part series. Learners first verify that multiplication by the reciprocal does the same geometrically as it does algebraically. The class then circles back...

Class members use the powers of multiplication in the 19th installment of the 32-part unit has individuals to utilize what they know about the multiplication of complex numbers to calculate the integral powers of a complex...

The class checks to see if the formula for finding powers of a complex number works to find the roots too.  Pupils review the previous day's work and graph on the polar grid. The discussion leads the class to think about...

Watch as matrices break networks down into rows and columns! Individuals learn how a network can be represented as a matrix. They also identify the notation of matrices.

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

The greater the latitude, the less of the Earth is north. Scholars graph the relationship between the latitude and the percentage of the Earth that is north of the latitude. Using the graph and the table, class members interpret values...

Use equivalent expressions to reveal information about their graphs. Pupils verify that two quadratic functions are equivalent. By comparing the two expressions, they determine the vertex, the zeros, the y-intercept, and the...

Scholars learn how to write number theory proofs by viewing a video reviewing techniques for proofs on divisibility, parity, and consecutive integers. They then write proofs for a handful of conjectures on a worksheet.

Sama Maydani and Sarah Kuck's film, Even the Walls, that explores the benefits and drawbacks of gentrification in downtown Seattle, asks viewers to consider how houses, apartment buildings, and outdoor spaces can be designed to build a...

Inspire teamwork in your classroom with a fun group activity. Peers pass a penny from the back of their hand to their classmate's hand, who passes it down the line, and see who wins the competition.

Here's a fun, creative approach to the profoundly important issue of human rights. Young citizens do three activities, two of which involve them finding images from magazines that reflect human rights of their...

Scholars voice their opinions about animal consciousness with an article that challenges common ideas about nature. After reading the article, learners engage in a thoughtful discussion before writing out their arguments...

Ever come across an unfamiliar word while reading and can't decipher its meaning? Use a worksheet and graphic organizer that tracks and helps bring meaning to unknown words as learners read a text. A worksheet and graphic organizer come...

Discover firsthand the effects of internal waves on coral reefs. Through a series of experiments, learners simulate internal waves and upwelling events as they make observations on the movement of water and other debris. They then...

In 150 BC, Seleucus of Seleucia theorized that the moon causes the tides. Scholars learn about what causes tides by studying the interactions of gravity between the sun, moon, and Earth. They use technology to formalize otherwise...

It's a jungle out there! Young biologists journey to Darien, Panama to examine the intricate relationships between the organisms that inhabit the jungle. Groups begin by demonstrating an understanding of energy flow in ecosystems, then...
