Intro. to Pre-Algebra

Students demonstrate different algebraic equations using Borenson's Hands-On Equation materials. They work in a cooperative group to solve algebraic equations.

Pre algebraic learners will be able to master conversion of fractions, decimals, and percents in no time when they use the illustrations on this resource.

This is the second in a series of 3 Khan Academy videos on rounding whole numbers. Students watch Sal Khan round the number 423,275 to the nearest thousand by looking to the number in the hundreds place. If it is 5 or higher, you round...

Rounding is an important skill which must be used throughout the study of mathematics. This Khan Academy video is the first in a series of 3. It shows how to round the number 24,259 to the nearest hundred, using a number line.

Explore the meaning of equivalent fractions. A video instructor shows the process of creating equivalent fractions both visually and mathematically. After explaining how to create equivalent fractions from the most simple form, she...

Find a relationship between different forms of numeric expressions. The video lesson explains the process of converting between fractions, decimals, and percents. The instructor models a problem starting with each of the three forms, so...

Examine an approach to adding measures of various units. An instructor demonstrates a horizontal approach to adding mixed measures by borrowing from the larger measures. The examples shown include time and length.

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...

Work through adding mixed fractions by first converting each fraction to an improper fraction. This video details each necessary step, including how to reduce and convert your improper fraction back into a mixed fraction after you have...

The first step in adding mixed numbers is to change them into improper fractions. Secondly, make sure the denominators are the same. If they are not the same, then find a common denominator. Make the proper conversions to the numerator...
