Exploring 2-Step Equation Modeling Techniques

The video tutorial covers modeling and solving two-step equations using three different methods: balanced models, algebra tiles, and cups and chips. The instructor explains each method step-by-step, demonstrating how to use inverse operations and zero pairs to solve equations. Students are encouraged to practice these techniques to reinforce their understanding.

What are the three types of models discussed in the video for solving equations?

• Balance, algebra tiles, and cups and chips

• Graphs, charts, and diagrams

• Functions, variables, and coefficients

• Equations, expressions, and calculations
