    I love the connection to algebra and algebraic thinking. To help students see the equation as a balance and to be able to visualize the answer would make it simpler to transition to the thinking that is necessary later on and it would make solving equations more understandable rather than an algorithm that they repeat put don’t really understand. To start a review of solving one-step equations in 8th grade and give it some meaning by showing the active subtraction makes total sense.
