What better way to celebrate students' birthdays than by creating original math problems? In this open ended challenge, young mathematicians must make numerical expressions using parentheses, exponents, and three other operations that...

All numerical expressions are not created equal. This quick exit card problem challenges young mathematicians' understanding of the order of operations as they try to determine which of five expressions are equivalent. Include this...

The problems in this video contain additional examples of scientific notation, continued from the previous presentation. Viewers have the opportunity to see Sal work through several more problems using the same techniques he has been...

Give your students the edge on their upcoming SAT with this video, which covers algebraic and linear equations. Math students who have a hard time transitioning between skills would benefit from seeing Sal do so.

Sal explains how helping his young cousins with their math skills inspired him to make this series of videos, so he can help a bunch of people pass the SAT. In this video, he covers exponents, quadratics, and parabolas in problems 5-9 on...

Sal demonstrates the methods needed to solve problems 8-10 in this video. He begins his lecture with a more thorough explanation of problem 7 (which he feels he "rushed" in the last video). These problems involve skills such as...

Fifth and sixth graders explore prime numbers. They work with a partner to build rectangular arrays using twelve tiles. Factor pairs are noted and recorded on graph paper. Pupils construct rectangular arrays with a prime number and...

Investigate rational exponents in this math lesson. Scholars make conjectures about the relationship between rational exponents and radicals. They then use their Ti-Nspire to simplify rational exponents.

For this 2-day lesson focused on exponents, middle schoolers will cross the curriculum by engaging in science, history and language arts activities. Exponential growth will be explored using grains of rice on a chess board. Exponential...

Transitioning between algebra and geometry is no problem for Sal as he deftly solves these practice SAT problems. Mathematicians who have a hard time moving between skill sets will appreciate the way that Sal addresses each new problem...

The most helpful part of this video is at the very end, when Sal demonstrates how to solve a combinations problem incorrectly (after initially finding the correct answer). The trial-and-error strategy of solving multiple-choice math...

Reviewing the last problem from the previous video because he feels that he "rushed it," Sal again explains the concept of ratios as it applies to problem 6 on the practice SAT (page 472 in The Official SAT Study Guide). Additional...

Page 459 of The Official SAT Study Guide by The College Board features another set of practice SAT math problems, beginning with problems 1-4. Sal demonstrates how to solve problems with factoring and visualization.

A new set of SAT practice questions from the Official SAT Study Guide (page 803) greets Sal and the viewer. Problems 1-7 involve basic algebraic equations, linear equations, and geometric figures.

"Demystifying" an often mysterious problem, Sal demonstrates some tricks for considering exponents intuitively, rather than working them out each time. He first takes viewers through positive exponents and works up to negative exponents,...

Create a human fraction to learn about division of exponents. Scholars develop the rule for division of exponents by being part of a human fraction to explore and justify the rule. They also consider zero exponents and negative exponents.

All hail the king! Young mathematicians put their skills to the test as they strive to become the king of math.

Go back in time and do the math for the major land purchases in US history. An activity testing skills in scientific notation and exponent rules allows learners to research the three major land purchases and use those findings for their...

What's the definition of the quotient of powers rule? Don't confuse this rule with the power of a quotient rule. This quotient of powers rule is quite simple in that you can just subtract. Wow! Take the power from the numerator and...

Subtract polynomials? Huh? First off find the additive inverse of the number you are subtracting. Next rewrite the polynomials one on top of the other. Make sure to line up the like terms and then write in placeholders. Now add the terms...

A quick lesson on how to write an exponential expression in expanded form. All you have to do is write out the base number the identified number of times as represented by the power. This would be a great support to your lesson on...

The instructor shows several different examples of the power of a product rule. She multiplies the values out, uses the commutative property of multiplication, and then simplifies the terms.

In this number sense and operations worksheet, learners solve 15 different types of problems that include reading number lines and solving inequalities. First, they write the scientific notation of various numbers given. Then, pupils...

For this algebra worksheet, problems containing exponents are solved by applying the properties of exponents. There are 10 questions with an answer key.
