Sal works through several problems involving rational and irrational numbers, and shows how to find the difference. This video is a good stepping stone for those who are preparing to take on more challenging algebra work.

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...

If your math students are having a hard time with graphing and slopes, this video could be a great resource as they prepare for the SAT. Sal takes care in explaining his thought process, making sure where to note different strategies to...

Continuing problem 7 from the previous video, Sal takes students through what he describes as "a common SAT problem" involving geometric lines and figures. Additional problems deal with sequences, cross-multiplication, and measuring...

Sal again makes the SAT look effortless, and yet students will follow his mathematical processes with ease. Problems range in difficulty, from basic algebra equations to more complicated geometric figures.

Spending more than half of the video readdressing the nuances in problem 13 (previously discussed in the last video), Sal ensures that students understand the tricky word problem by going through each of the multiple choice answers....

Have a blast with Sal as he solves these SAT practice questions! He enjoys himself with visualization and combination problems, showing not only how to solve the problems but to see math as a riddle rather than a threat.

This lesson has a number of fun worksheets for a pre-algebra or beginning algebra class. The main emphasis of this lesson is functions, formulas, and looking at square roots. It is the third lesson in a series on solving for unknowns,...

Continuing his theme of solving problems in a timely and correct manner, Sal teaches students that most problems on the SAT are designed to be solved in less than 30 seconds (though he does state that they are given over a minute for...

Sorting fractions, integers, decimals and square roots into sequential order is an active process when you use a gym as your setting. After your class is divided into two groups and provided with number cards, they compete to see who can...

Learners examine a Babylonian clay tablet and the mathematics found on it as a catalyst to investigate a variety of mathematical ideas. They work with prime numbers, classify numbers as whole, integer, rational, or irrational and use...

A narrator shows us what some basic graphs are and the equations that produce certain graphs. He does not actually explain how to graph but simply shows different types of graphs.

In this algebra worksheet, students solve 10 equations for the given variable. Each problem involves numbers under a radical sign.

Eighth and ninth graders solve and complete 6 different types of word problems. They use their knowledge to solve a number of word problems involving exponents, square roots and scientific notation and use a calculator to perform the...

Students explore the concept of estimating square and cube roots.  In this estimating square and cube roots lesson plan, students are given the area of a square object and must determine the sides.  Students solve word problems involving...

In this square roots worksheet, students find the square roots of numbers, find what numbers are squared, solve for lengths of sides of triangles, and more. Students complete 18 problems.

Teach numbers in word form with this activity. In this numbers and operations activity, learners solve 22 problems in which numbers are written in word form. Students solve the problems and write their responses in word form. Example:...

In this algebra worksheet, students simplify 14 complex radical fractions. They find the square roots for both the denominator and numerator, dividing out any factors that are the same to completely simplify the fraction. For the final 7...

In this radical worksheet, pupils simplify radicals by identifying the root, and rationalizing the denominator. They complete 40 multiple choice answers.

In this algebra worksheet students find the root and simplify 20 radical expressions. Students use the product and quotient rules to simplify 27 radical expressions. They add or subtract radicals on 13 problems.

Looking for a quick introduction or review for area formulas?  Terminology and formulas for the area of squares, rectangles and triangles is presented. Connections with exponents and the Pythagorean Theorem are demonstrated.

Have your class practice solving algebraic equations, finding the square root of a number, and more. This activity allows learners to practice key skills in a motivating way.

In this square roots worksheet, learners solve an algebra problem involving square roots and then determine which of the options is closest to the correct answer to the problem. There are 8 problems on this page.

Students explore the concepts of square roots and exponential expressions. In this square root and exponential expression lesson, students complete an investigation called Building A Square Patio. Students use color tiles to develop the...
