Shrinkflation

Are your favorite snacks secretly shrinking? Students compare the size and price of three popular snacks in 2022 versus 2026, calculating each item's unit price and percent change to uncover "shrinkflation". They then measure their results against inflation and track down shrinkflation in a snack of their own. Along the way, they build real fluency with unit rates, percent increase, and proportional reasoning. Begin the activity with the starter slides.
