[FT] AMPLIFY 6.6.01: Detecting Counterfeit Coins

Students explore the physical concept of balance as they model weighing different numbers of coins to identify a counterfeit among them. All students will be able to engage with these tasks by applying some repeated reasoning, taking the form of a combination of guess-and-check, brute force, or higher-order thinking and logic (MP1, MP8). This lesson sets the stage for the important concept of balance as it relates to algebraic expressions and equations, which will be carried into all the lessons that follow.
