After this lesson, you will be able to visualize mathematical statements and translate them into a equation using variables.

The lesson begins by teaching you that mathematical statements can be written in the form of an equation. It leads you to learn how to translate mathematical keywords into variables and operations. It concludes with a note that when writing equations, keywords are the solution!

Learn about writing equations using variables by helping Leyla visualize what she heard from the whispering swamp.

This video includes key concepts, notation, and vocabulary such as the term variable (an unknown quantity usually represented by a letter); consecutive integers (numbers that follow each other in order like 1,2,3, etc.); and math keywords (words which correspond to a mathematical operation or expression).

Before watching this video, you should already be familiar with the different math keywords such as “consecutive integers”, “less than”, “half of the square”, etc.

After watching this video, you will be prepared to learn how to translate verbal phrases into mathematical expressions and solve real-life problems involving a mathematical equation.
