Visualizing 1 Step Equations in 5th Grade Math

The video tutorial introduces the concept of using visual models to solve one-step equations. It begins by explaining key vocabulary such as variables, equations, and open sentences. The tutorial then demonstrates how to use balance models to visually represent equations, using stars and squares to symbolize variables and numbers. The instructor guides viewers through building visual models for specific equations and encourages them to create their own equations from given visual models, focusing on addition and subtraction.

What is a variable?

• A type of equation

• A number that is always known

• A letter or symbol representing an unknown number

• A mathematical operation
