Greater than and less than basics

5 videos
4 skills
Equality is usually a good thing, but the world is not a perfect place. No matter how hard we try, we can't help but compare one thing to another and realize how unequal they may be. This tutorial gives you the tools to do these comparisons in the mathematical world (which we call inequalities). You'll become familiar with the "greater than" and "less than symbols" and learn to use them.

Inequalities: plotting on a number line

VIDEO 6:14 minutes
We've been taking a lot of equalities. What about when the relationships between numbers need to be expressed as inequalities? For example, less/greater than and/or equal to? How can we represent that idea on a number line?

Inequality word problems

VIDEO 3:28 minutes
We're writing inequalities by using information from the word problems. Woohoo!

Inequality word problem: one variable

VIDEO 2:27 minutes
This time we're creating a variable to represent a number, and then writing an inequality. We're building on our knowledge.
