Get third graders excited to work find area and perimeter of unit squares, rectangles, and irregular shapes. A 36-page packet comes with task cards, graphic organizers, practice worksheets, printables with squares, exit tickets, and word...

Work your way through factoring polynomials with a worksheet that starts with the GCF and ends with factoring by grouping. Each page provides an example as well as an answer key for each section. 

Several examples of different types of algebraic expressions are multiplied. The distributive property is used to demonstrate the steps needed to multiply the terms in the expressions. Sal combines the like-terms at the end of the...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps - though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

The beginning of a new set of SAT practice problems from The Official SAT Study Guide involves sequences, distribution, combinations, and geometric figures. Sal makes sure to provide thorough explanations to each problem, while...

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.

This video is great preparation for order of operations and linear equations. There are two videos on the distributive property of multiplication. The first one showed why distribution works. This one shows the process in a clear and...

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 clear, Sal explains not only how to use the distributive property but, with...

Learners identify the properties and use them to solve word problems. They solve 13 problems. This is an unusually good worksheet!

Eighth graders combine like terms in this properties of variables lesson. Using named items (stars, moons and hearts), they combine like terms using variables. They use the distributive property to combine like terms. Finally, they write...

Some polynomials, when multiplied, result in a special product. Sal uses the distributive property to demonstrate the multiplication process. He then explains why some polynomials cannot be completely simplified.

Reinforce multiplication strategies with a lesson that examines a word problem and the distributive property. Mathematicians work collaboratively to solve the problem, create a poster with their solution, and share their preferred method...

Prove the best way to keep up in Geometry. Scholars first review algebraic properties from Algebra. Learners then use the properties to create two-column proofs to solve linear equations before completing algebraic proofs by providing...
