1. Accounting Equation in Action | 会计等式实操
Mia starts a bracelet-making business. She invests $400 of her own savings and borrows $150 from her parents. She immediately buys beads and thread for $200 in cash. Let us see how each transaction keeps the accounting equation in balance.
米娅开办手链制作生意。她投入自己的储蓄 400 美元，并从父母那里借了 150 美元。她立即用现金 200 美元购买了珠子和线。让我们看看每笔交易如何保持会计等式平衡。
After the initial investment and borrowing, total assets are $550 (Cash $550), liabilities are $150, so Mia’s equity is $400.
初始投资和借款之后，总资产为 550 美元（现金 550 美元），负债为 150 美元，因此米娅的所有者权益为 400 美元。
Assets = Liabilities + Equity → $550 = $150 + $400
她购买材料时，现金减少 200 美元，但存货增加 200 美元。等式仍然平衡。
When she buys materials, cash decreases by $200 and inventory increases by $200. The equation remains balanced.
After the purchase: Cash $350 + Inventory $200 = Liabilities $150 + Equity $400. Both sides equal $550.
购买后：现金 350 美元 + 存货 200 美元 = 负债 150 美元 + 权益 400 美元。两边均为 550 美元。
2. Calculating Gross Profit from Given Data | 根据数据计算毛利润
Gross profit shows how efficiently a business turns raw materials into sales. It is the difference between revenue and cost of sales. Consider Mia’s first week of selling bracelets.
毛利润反映企业将原材料转化为销售的效率。它是销售收入与销售成本之间的差额。以米娅第一周销售手链为例。
She sold 15 bracelets at $8 each. The beads and thread used cost $3 per bracelet. Her total revenue was 15 × $8 = $120. Cost of sales was 15 × $3 = $45.
她以单价 8 美元出售了 15 条手链。使用的珠子和线成本为每条 3 美元。总收入为 15 × 8 美元 = 120 美元。销售成本为 15 × 3 美元 = 45 美元。
Gross Profit = Revenue − Cost of Sales → $120 − $45 = $75
毛利 75 美元意味着米娅每卖出一条手链能赚取 5 美元，经得起与数学课上学到的单位贡献利润概念进行比较。
A gross profit of $75 means Mia earns $5 per bracelet sold, which can be compared with the unit contribution concept learned in mathematics.
3. Applying Discounts: Trade and Cash | 应用折扣：商业折扣与现金折扣
Discounts are common in business and require careful percentage calculations. A trade discount is deducted from the list price before any transaction is recorded. A cash discount is offered for early payment.
折扣在商业中很常见，需要仔细进行百分比计算。商业折扣在记录交易前就从价目表价格中扣除。现金折扣是为了鼓励提前付款而给予的优惠。
Mia orders a batch of gift boxes listed at $50. The supplier offers a 20% trade discount. The net price after trade discount is $50 × (1 − 0.20) = $40.
米娅订购一批标价 50 美元的礼盒。供应商提供 20% 的商业折扣。扣除商业折扣后的净价为 50 美元 × (1 − 0.20) = 40 美元。
If she pays within 10 days, she receives a further 5% cash discount on the net price. The final payment would be $40 × (1 − 0.05) = $38.
如果她在 10 天内付款，还能在净价基础上获得 5% 的现金折扣。最终付款为 40 美元 × (1 − 0.05) = 38 美元。
This sequence is similar to multi-step percentage problems in mathematics, reinforcing the link between accounting and numerical fluency.
这一计算顺序与数学中的多步骤百分数问题类似，强化了会计与数字运算能力的联系。
4. Drawing up a Simple Income Statement | 编制简易利润表
An income statement summarises revenue and expenses over a period. It helps owners see whether the business made a profit or a loss. Mia decides to prepare one for her first month.
利润表汇总了某一期间内的收入和费用，帮助所有者了解企业是盈利还是亏损。米娅决定为第一个月编制一份利润表。
| Revenue | $420 |
| Less: Cost of Sales | ($165) |
| Gross Profit | $255 |
| Less: Other Expenses (stall fee) | ($30) |
| Net Profit | $225 |
The table shows Mia earned $420 from sales, spent $165 on materials, and paid a $30 stall fee, leaving a net profit of $225. Such a format is a practical application of column subtraction and introduction to profit measurement.
此表显示米娅销售收入 420 美元，材料花费 165 美元，支付摊位费 30 美元，净利润为 225 美元。这种格式是列减法和对利润计量的入门实践。
5. Building a Statement of Financial Position | 编制财务状况表
Also called a balance sheet, this statement shows what a business owns (assets), what it owes (liabilities), and the owner’s equity on a specific date. Mia wants to know her financial position at month-end.
也称为资产负债表，该报表列示企业在某一特定日期拥有什么（资产）、欠什么（负债）以及所有者权益。米娅想知道月底的财务状况。
She has $280 cash, $40 of unsold inventory, and still owes her parents $150. No other debts exist. Her equity can be calculated.
她有现金 280 美元，未售出存货价值 40 美元，仍欠父母 150 美元，没有其他债务。可以计算她的权益。
Total Assets = Cash $280 + Inventory $40 = $320
Equity = Total Assets − Liabilities = $320 − $150 = $170
Comparing equity at the start ($400) and now ($170) might seem a drop, but remember she withdrew some profit for personal use. This links to the concept of drawings, which helps connect accounting records with everyday money management.
比较初始权益（400 美元）和当前权益（170 美元）似乎下降了，但要记得她提取了部分利润供个人使用。这联系到提款的概念，有助于将会计记录与日常资金管理联系起来。
6. Interdisciplinary with Mathematics: Percentages & Ratios | 与数学跨学科：百分数及比率
Accounting relies heavily on percentages and ratios. After preparing her statements, Mia calculates her net profit margin and mark-up percentage to evaluate performance.
会计严重依赖百分数和比率。在编制报表之后，米娅计算了净利润率和成本加成率，以评估业绩。
Net Profit Margin = (Net Profit ÷ Revenue) × 100% = ($225 ÷ $420) × 100% ≈ 53.6%
这表示每 1 美元销售收入中约有 53.6 美分是净利润，这一比率可与数学课上的比例推理练习直接挂钩。
This means that for every $1 of sales revenue, about 53.6 cents is net profit, a ratio that directly ties to proportional reasoning exercises in mathematics.
She also computes mark-up on cost: (Gross Profit ÷ Cost of Sales) × 100% = ($255 ÷ $165) × 100% ≈ 154.5%. This shows the percentage added to material costs to reach the selling price.
她还计算了成本加成率：（毛利 ÷ 销售成本）× 100% =（255 美元 ÷ 165 美元）× 100% ≈ 154.5%。这表明在材料成本基础上加价的比例。
Practising these calculations strengthens both accounting analysis and mathematical problem-solving with real data.
练习这些计算能同时强化会计分析和利用真实数据的数学解题能力。
7. Linking to Science: Estimating Inventory Losses | 联系科学：估算存货损失
Science experiments can explain why some inventory becomes unsellable. Imagine Mia stores her bracelets in two conditions: dry room and humid shed. After one week, bracelets in the humid shed show tarnish on metal parts, reducing their value.
科学实验可以解释为什么有些存货会变得无法销售。假设米娅将手链存放在两种条件下：干燥的房间和潮湿的棚屋。一周后，潮湿棚屋中的手链金属部件出现锈蚀，价值下降。
She had 20 bracelets in the shed, originally costing $3 each. Due to damage, she can only sell them at $1 each. The loss per bracelet is $2. Total inventory write‑down is 20 × $2 = $40.
她在棚屋中有 20 条手链，原成本每条 3 美元。由于损坏，只能以 1 美元出售。每条损失 2 美元。存货减记总额为 20 × 2 美元 = 40 美元。
This write-down reduces gross profit and teaches the importance of proper storage conditions – a clear bridge between accounting records and scientific observation.
这笔减记会减少毛利，并教会我们合理储存条件的重要性——这是会计记录与科学观察之间的清晰桥梁。
8. Geography and Budgeting: Planning a Fundraiser | 地理与预算：策划筹款活动
Mia’s class wants to run a charity cake sale. They must choose between two locations: the school foyer (free but limited footfall) and the local park ($20 permit fee but high footfall). Geography skills help assess advantages of each site.
米娅的班级想举办慈善蛋糕义卖。他们必须在两个地点之间选择：学校大厅（免费但人流有限）和当地公园（需 20 美元许可费但人流量大）。地理技能有助于评估每个地点的优势。
The budget assumes selling 50 cakes at $2 each. Cost of ingredients is $0.80 per cake. Without permit fee, expected profit: Revenue $100 − Cost $40 = $60. If the park is chosen, permit fee reduces profit to $40.
预算假设以单价 2 美元出售 50 个蛋糕，原料成本每个 0.80 美元。若无许可费，预期利润为：收入 100 美元 − 成本 40 美元 = 60 美元。若选择公园，许可费使利润降至 40 美元。
However, geography tells us the park may attract 80 customers instead of 50. Recalculated profit: Revenue $160 − Cost $64 − Permit $20 = $76. The location decision changes the financial outcome, integrating geographical reasoning with accounting profits.
然而，地理知识告诉我们，公园可能吸引 80 名顾客而非 50 名。重新计算利润：收入 160 美元 − 成本 64 美元 − 许可费 20 美元 = 76 美元。地点决策改变了财务结果，将地理推理与会计利润融为一体。
9. Ethical Decision Making in Small Business | 小型企业中的道德决策
Accounting is not only about numbers; it also involves making ethical choices. Mia can buy cheaper beads from Supplier A for $2 per bracelet, but they are rumoured to use child labour. Supplier B charges $3 per bracelet and follows fair trade.
会计不仅仅是数字，还涉及做出道德选择。米娅可以以每条手链 2 美元的价格从供应商 A 购买更便宜的珠子，但传闻其使用童工。供应商 B 收费 3 美元并遵循公平贸易。
If she sells 30 bracelets at $8 each, using Supplier A gives a gross profit of ($8 − $2) × 30 = $180. Using Supplier B gives ($8 − $3) × 30 = $150. The profit difference is $30.
若她以 8 美元单价出售 30 条手链，使用供应商 A 的毛利为（8 − 2）× 30 = 180 美元。使用供应商 B 的毛利为（8 − 3）× 30 = 150 美元。利润差额为 30 美元。
链接到价值观和公民教育，米娅需要考虑长期声誉和顾客感受。许多顾客愿意为道德产品支付更高价格，这可能会增加销售额。这只是一种跨学科整合，涉及道德哲学和商业会计。
Linking to values and citizenship education, Mia must consider long-term reputation and customer feelings. Many customers may pay extra for ethical products, potentially increasing sales volumes. This is an interdisciplinary blend of moral philosophy and business accounting.
她的决策可以通过简单的成本效益分析来支持，使用会计数据展示收益差异，并与道德动机进行比较。
Her decision can be supported by a simple cost‑benefit analysis, using accounting data to show profit differences and weigh them against ethical motives.
10. Integrated Question Walkthrough: The Lemonade Stand | 综合题型演练：柠檬水摊
Lucas runs a lemonade stand. He starts with $50 cash, buys lemons and sugar for $22, and sells 40 cups at $1.50 each. However, science tells us that lemon juice oxidises, so 5 cups’ worth of ingredients spoil. Geography influences whether he sells more near the sports field or the library. Let’s work through the accounting while weaving in other subjects.
卢卡斯经营一个柠檬水摊。他以 50 美元现金起步，花 22 美元购买柠檬和糖，以每杯 1.50 美元卖出 40 杯。然而，科学告诉我们柠檬汁会氧化，因此相当于 5 杯的原料变质。地理因素会影响他在运动场旁还是图书馆旁卖出更多。让我们一边处理会计问题，一边融入其他学科。
Step 1 – Calculate revenue: 40 cups × $1.50 = $60. 步骤 1 – 计算收入：40 杯 × 1.50 美元 = 60 美元。
Step 2 – Determine cost of sales: Ingredients cost $22, but spoilage wastes 5/40 of the batch, valued at ($22 ÷ 40) × 5 = $2.75. Effective cost of goods sold = $22 − $2.75 = $19.25. 步骤 2 – 确定销售成本：原料成本 22 美元，但因变质浪费了 5/40 的材料，价值为 (22 ÷ 40) × 5 = 2.75 美元。实际销售
