Sal first solves a couple of equations using the factoring method he has already taught. Next, he introduces the quadratic formula and demonstrates how to plug the numbers from the quadratic equation into the quadratic formula....

The instructor continues solving quadratic equations by plugging values into the quadratic formula. These examples are a bit more difficult because the answers do not work out to whole numbers.

Paper folding, flu spreading in a school, bacteria growth, and continuously compounded interest all provide excellent models to study exponential functions. This is a comprehensive resource that looks at many different aspects of these...

Explore the concept of polynomials and determine the value and number of zeros for a given polynomial using the Rational Root Theorem. Then graph the polynomials and relate the number of zeroes to the degree of the polynomial.

Combine the given radical expressions. How? Do they have the same radical? Yes. Then they can be combined. Watch this video as the teacher explains how to combine the terms that can be combined and leave the terms as they are that need...

First, review the location principle and then use a table to determine the zeros for the function your trying to solve. This tutorial defines the location principle, works through a table, identifies where sign changes occur, then uses...

Asexual reproduction in plants occurs from bulbs, perennating organs, or even gardening techniques like cuttings. Commercial growers rely on the ability of some plants to reproduce asexually and grow roots rather than starting from...

Explore a few powers of complex numbers numerically and decide if there is a pattern and use parametric equations to represent a complex number graphically. Use De Moivre's theorem to represent the roots of the complex number...

Plant roots are the focus here. Pupils discover that some plants actually store food in their roots, that roots provide water for plants, and that gravity and sunlight have an effect on plants. This terrific, six-page plan has two...

Here is a good, basic, and solid lesson plan on the parts of a plant. Young biologists learn about the parts of a plant, and what each one does. Additionally, learners look at the parts of plants that are used by people and determine...

The roots metro/meter and therm are the focus of a vocabulary building presentation that includes concise definitions, color-coded examples, and opportunities for guided and independent practice. Part of a series of roots and affixes...

Here is an opportunity for your first graders to take a close look at plants: what they need to survive, how they grow, and the names of each plant part. The book, Corduroy's Garden is used to open the lesson. Then, youngsters utilize...

Exponential functions are the name of the game. Young mathematicians can work through each of the eight worksheets by evaluating functions, applying logarithms, completing logarithmic functions, and building inverse functions. This would...

Who doesn't need to know the Fundamental Theorem of Algebra? Use the theorem to find the roots of a polynomial on a TI calculator. The class explores polynomials with one solution, no real solutions, and two solutions. This less lesson...

Solve two-step equations using order of operation in this algebra lesson. Young mathematicians evaluate functions through substitution and apply the properties of exponents and negatives correctly. They complete the order of operation...

Practice root words with this word search worksheet. Young readers locate thirty-five word roots given in the word box. They find the words in a puzzle consisting of fifteen rows and thirty-five columns.

Here is what a PowerPoint presentation should look like! This excellent show lets students know what they will be learning about, takes them through nicely-designed examples, leaves room for discussion questions, has a built-in activity,...

The verbal and quantitative sections of the SAT can be a challenge for even the most erudite logophile. Prepare your test takers for the vocabulary they will encounter on standardized exams by providing them with a helpful list of roots,...

Subtract the given radicals. Not so difficult really! If the radicals are like terms, then it's as simple as combining the coefficients. Yes, it's really that simple.

Radicals , radicands , square roots, perfect squares, and subtracting? Sounds complicated, especially because the radicals are not the same in this problem. So, there's a lot of math work to do here. Watch this video to find out how to...

Looking at an image of plant systems with their roots in the ground, learners determine which would be the most or least difficult to pull. They write short sentences describing which plant they chose and why. Intended for 3rd or 4th...

Nonverbal, nonfat, nonfiction. The prefix non- (meaning not) is the focus of this affixes presentation that concludes with a check for understanding.

The roots port and voc are the focus of a practice sheet that asks learners to complete a series of sentences using words provided by a word bank.

The Latin roots sent/sens, soph, and tend/tent  are featured in this vocabulary-building vocabulary presentation. The definition of the root is provided and then a word built on this root is used in a sentence.
