Welcome to "Orbit Mart Tally", a Grade 2 Counting Money (Dollars & Cents) mission at the Seedling warm-up level, staged in a space scenario. The mission opens with a hands-on prompt: "Begin by stacking the nickels: 4 nickels (each worth 5¢)." Students work with the numbers 4, 5, 6 and reach a final answer of 24 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: 4 nickels + 6 pennies = 26¢.
A common misconception this page surfaces is: Mixing dollars and cents into one number without converting. 100¢ = $1. They are the same currency at different scales — convert before adding. The adaptive Socratic hints move from a small nudge to a fuller strategy, keeping the reasoning visible for students, parents, and teachers.

This seedling · gentle warm-up 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: 4 is the COUNT of coins, not the value. Each nickel = 5¢.
Common wrong turn: That's the COIN COUNT, not the cent total. Each coin's value matters.
Common wrong turn: 26¢ 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: 4 nickels + 6 pennies = 26¢. A useful check is to ask whether the answer avoids this pitfall: Mixing dollars and cents into one number without converting. 100¢ = $1. They are the same currency at different scales — convert before adding.
