Core Skills Analysis
Mathematics
The 10‑year‑old counted the keychains in inventory, recorded purchases, and used a spreadsheet to calculate total costs, revenue, and profit. By adding up the price of each batch of stock and subtracting that from the money earned from sales, the child practiced addition, subtraction, and multiplication of whole numbers and decimals. They also learned how to organize data in rows and columns, interpret totals, and check their work for accuracy.
Business & Economics
The student acted as a young entrepreneur by buying keychain stock, setting prices, packaging items, and selling them in a store. Through this process they discovered concepts such as cost of goods, pricing strategies, profit margin, and cash flow. Keeping track of sales and expenses on a spreadsheet gave them a concrete sense of how businesses stay financially viable.
Computer/Technology
Using a spreadsheet program, the child entered inventory numbers, calculated formulas, and generated simple reports. This activity introduced basic digital literacy skills like cell referencing, using built‑in functions, and formatting data for readability. The experience showed how technology can streamline record‑keeping and support decision‑making.
Tips
To deepen the learning, have the child create a price‑tag worksheet that compares different selling prices and predicts profit changes. Next, set up a mock “bank” where they deposit daily earnings and withdraw money for future inventory, reinforcing budgeting concepts. Encourage them to design a short advertisement poster or social‑media post to practice persuasive language and visual design. Finally, invite the child to interview a local shop owner about real‑world inventory management and discuss the similarities and differences.
