Welcome to "Bakery Cashier Lab", a Grade 2 Counting Money (Dollars & Cents) mission at the Challenger stretch problem level, staged in a bakery scenario. The mission opens with a hands-on prompt: "Begin by stacking the dollar bills: 2 dollar bills (each worth 100¢)." Students work with the numbers 2, 100, 3 and reach a final answer of 25 across 3 guided steps.
Behind the story, this lesson builds counting money (dollars & cents) understanding aligned to CCSS 2.MD.C.8. The key strategy is: 2 dollar bills + 3 quarters = 275¢.
A common misconception this page surfaces is: Treating each coin as 1¢ regardless of its denomination. Each coin has a NAME and a VALUE — quarter = 25¢, dime = 10¢, nickel = 5¢, penny = 1¢. Memorize the table first. The adaptive Socratic hints move from a small nudge to a fuller strategy, keeping the reasoning visible for students, parents, and teachers.

This challenger · stretch problem mission uses a equal-groups model to move from the story to a precise counting money idea. Work through the prompts in order: notice the structure first, name the quantities, then check whether the final answer fits the original situation.
Common wrong turn: 2 is the COUNT of coins, not the value. Each dollar bill = 100¢.
Common wrong turn: That's the COIN COUNT, not the cent total. Each coin's value matters.
Common wrong turn: 275¢ is what you HAVE, not what's missing.
In 2nd Grade Counting Money, students need to connect the story, the model, and the symbolic answer. The core move here is: 2 dollar bills + 3 quarters = 275¢. A useful check is to ask whether the answer avoids this pitfall: Treating each coin as 1¢ regardless of its denomination. Each coin has a NAME and a VALUE — quarter = 25¢, dime = 10¢, nickel = 5¢, penny = 1¢. Memorize the table first.
