Predict the number of blocks you need to equal the weight of one bag and then test your theory. This interactive exercise focuses on using critical thinking skills to add and subtract items on the scales to achieve balance and visual problem solving. This resource is part of the Math at the Core: Middle School collection.

Balance when Adding and Subtracting. Algebra is great fun - you get to solve puzzles! When we add or subtract the same thing from both sides the equation stays in balance. Watch the equation below. Use the +x, −x, +1, −1 buttons. Try to get "x = (something)" Things to try. Each "equation" will have a solution like "x=2" (or maybe "x=3", etc).
