Math

• The child learned to calculate the total price of their used items and determine appropriate selling prices.
• They practiced basic addition and subtraction skills while keeping track of their inventory and sales.
• They applied percentages to offer discounts or negotiate prices with potential buyers.
• They gained an understanding of profit and loss by comparing the selling price with the original cost of the items.

For continued development related to this activity, encourage the child to explore more advanced concepts in mathematics. They can analyze sales data to identify trends and patterns, calculate profit margins and sales tax, or even create charts and graphs to visually represent their sales performance.
