Algebra2go: Demonstrating Equivalent Fractions Using Number Lines Part 2

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

Estimating the value of numbers is much harder than it sounds! Scholars compare and order the value of numbers presented in different forms including fractions, decimals, roots, integers, and pi. This builds on the previous lessons in...

Problem number 6 on the practice SAT involves solving for a distance on a line, which Sal does in about 2 minutes. His method of efficiently (and correctly) solving problems is an excellent model for students who tend to panic at the...

Sal notes the important of reading a question very carefully in this video, as he nearly misreads a problem but catches his error before it's too late. Most problems shown here involve algebra skills.

Put fractions with different original denominators in order using the least common denominator. Once she has shown how to find the least common denominator, an instructor constructs equivalent fractions that are more easily compared to...

Not all fractions are created equal. Scholars review how to create equivalent fractions by multiplying the numerator and denominator by the same factor. A short instructional video covers a few examples of the concept.

How can you tell if 2 fractions are equal or different when they have different denominators? Watch this video to find out! A tutorial on common denominators, this video explains each step necessary to find common denominators, create...

The instructor demonstrates how to read a number line graph to write an inequality. There are several steps involved which are explained clearly.

The teacher shows how draw a number line and graph an inequality using an open circle. She also shows how to graph a set of numbers on a number line.

Video tutorial presents problems to practice converting fractions to repeating decimals. (Part 2) [4:27]
