✂️ Quick Budget Poster Prototype

Teams create a low-fidelity tri-fold poster using chart paper, sticky notes, markers, play money, and pre-made item cards. They include 3–5 snack items, labeled prices, addition equations for totals, and a subtraction equation from $20 to show remaining budget. Students add at least one visual model (number line or ten-frame) and set up a simple play-money interaction for visitors to test.
