Simplifying Hangers and Equations

The video tutorial covers Activity 1 from Lesson 3, focusing on simplifying hangers A to D. The process involves removing shapes while keeping the hangers balanced, ultimately matching equations to the simplified hangers. The tutorial explains each step in detail, from the most complex hanger A to the simplest hanger D, and provides insights into the corresponding equations. The video also includes a detailed analysis of symbol matching for the equations.

What is the main goal of Activity 1: Matching Hangers?
