Awareness of Pre-algebra Concepts

Let your classes show you what they know! Use this pre-test to assess the current knowledge of your learners. The assessment includes all pre-algebra concepts related to functions: writing and graphing linear relationships, comparing...

Math really is just one big puzzle waiting to be solved. Show learners that math can be intriguing and provide them with visually engaging problems and puzzles. The focus is on solving simple equations and looking at expressions. 

Hello Algebra! If you're in need of a resource with a books worth of examples and practice problems, this is it. Some topics include linear equations, polynomials and exponents, rational expressions, quadratic equations, and a...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

Sal tackles pre-algebra in this series of videos, starting with the concept of negative numbers. Using a number line, he takes the viewer through different practical examples of negative numbers, such as temperature and bank accounts....

This video contains additional scientific notation examples, continuing from the previous presentation. Viewers can see Sal work through several more problems using the techniques he has outlined throughout the pre-algebra video series.

Elementary schoolers observe Sal evaluate the expression 4(8+3) and then use the distributive property to solve it. Using different colors to make the process transparent, Sal explains not only how to use the distributive property but,...

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 preparing to take on more challenging algebra work.

This video shows how to locate and plot a decimal number on a number line. Practice problems are available. [1:39]
