2026—2027学年 沪教版七年级英语上册 Unit 7 U7 cross curricular connection 学案 2026—2027学年沪教版七年级英语上册 跨学科探究课 用图表说明课后运动 班级 __________ 姓名 __________ 日期 __________ 教材对应：第112页 Mathematics How active are you。建议用时：40分钟。 本课任务 读懂三种图表，检查数据结论是否可靠，再为一次课后运动调查选图并提出建议。 重难点 读准标题、单位和图例；区分人数与运动时长；依据样本作适度结论。 一 先想问题再选图 5分钟 1. Look at charts a, b and c on p. 112. Match each question with the most suitable chart. Explain the match with its purpose. Question Chart letter What the chart does Which sports do boys and girls play? _____ compares different __________ How did Fiona’s steps change during the week? _____ shows change over __________ How many students are in each weekly sports-hour group? _____ shows parts of one __________ 词语支架：bar chart 柱状图；line chart 折线图；pie chart 饼图；data 数据；survey 调查。 二 数字要带着单位读 8分钟 2. Read chart a. Complete the facts and calculate the difference. a. ______ boys and ______ girls play football. b. ______ more boys than girls play football. c. Among girls, the largest number shown is for __________________. d. ______ students in total play table tennis, according to the chart. 3. Read chart b. On which TWO days did Fiona take the most steps? About how many steps did she take on each of those days? Days: _________________________ Steps per day: about __________________ Why is “about” helpful when reading this graph? __________________________ ____________________________________________________________________. 4. Read chart c. The number 4 in one part means ______ students did ______ hours of sport a week. The chart includes ______ students altogether. 写出加法核对总人数：__________________________________________________ 用图表检查一句话是否站得住 读图顺序：标题 → 横纵轴或图例 → 单位 → 数据。饼图里的人数和图例里的小时数不能混用。 三 给结论找证据也找边界 9分钟 5. Evaluate the claims. Write supported or not supported. Use a number or a clear reason from the charts. a. “Twice as many boys as girls play football in Class 7B.” Decision: ____________________ Evidence: ______________________________ b. “Fiona walked less and less every day of the week.” Decision: ____________________ Evidence: ______________________________ c. “The 10 in the orange part of the pie chart means ten per cent.” Decision: ____________________ Evidence: ______________________________ d. “The four girls’ bars add up to 20, so there must be 20 different girls in the class.” Decision: ____________________ Evidence: ______________________________ ________________________________________________________________________ 思考支架：同一个人能不能参加两种运动？图中有没有说明每人只能选一种？ 四 调查方式会不会改变结论 6分钟 6. A school wants to choose a new after-school sports activity. Which survey is more useful? Explain one reason. A. Ask only the 12 students already in the Basketball Club. B. Ask students from different classes, including students who do not belong to a sports club. I choose ____ because __________________________________________________ ____________________________________________________________________. 7. Improve this survey question so that it does not push students towards one answer: “Basketball is great. You want another basketball club, don’t you?” ________________________________________________________________________ ________________________________________________________________________ 可用结构：Which … would you most like to …? Choose one. A sample tells us about the people we asked. Before saying “all students”, check who took part in the survey. 选择图表并作出有限度的建议 五 把一份课堂数据画清楚 8分钟 8. Use this practice dataset, separate from the textbook survey. Thirty students from one class each chose ONE new sports activity. All 30 answered. Activity Basketball Table tennis Running Dance Students 12 8 6 4 For comparing the four numbers, a __________ chart is suitable. Explain why a line chart would be less suitable here. Reason: _____________________________________________________________ Draw four bars on the grid. Keep the same bar width. Check your scale and total. 六 给体育老师写一句有证据的建议 4分钟 9. Write 35–50 words. Include the most popular choice, one numerical comparison, a suggestion, and one limit of the survey. 支架：Among these 30 students, … . … more students chose … than … . The school could … . However, … . ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 10. Before making a whole-school decision, what further information would you collect? Give one question. ____________________________________________________________________? 课后小调查 选做 用修改后的问题询问5名同学，记下每人一个选择。报告只写 “Among these five students …”，不替全校下结论。 参考答案与教学提示 开放题所列答案仅作示例。表达不同但符合文本、理由成立，应予认可；先肯定思考依据，再帮助学生修正语言。 一至二 读图与计算 1. a—groups；b—time；c—group。柱状图便于比较类别或群体；折线图表示一段时间内的变化；饼图显示一个整体的各部分。 2. a：12，6；b：6；c：skating；d：3（2 girls + 1 boy）。单位都是 students，不是 hours。 3. Tuesday and Thursday；about 11,000 steps on each day。图中没有给每个点标出精确数字，读数需参照纵轴估计，用 about 更审慎。 4. 4 students；14 hours；26 students。2 + 4 + 10 + 10 = 26。图例把颜色对应到每周小时数，扇区标注的是各组人数。 三 结论是否超出了证据 5a. Supported. 12 is twice 6. 不能把“多6人”说成“多6倍”。 5b. Not supported. Her steps rose from Monday to Tuesday and from Wednesday to Thursday. 即使后半周下降，也不能概括为每天都减少。 5c. Not supported. It means 10 students, not 10 per cent. Orange represents the group doing 10 hours of sport a week. 人数和小时数恰好都为10，更需要区分。 5d. Not supported. A girl may play more than one sport. The chart does not state that each person can appear in only one category. 各柱相加得到20个参与记录，不能据此确定20名不同女生；也不能反向断言一定存在重复，因调查选项规则未交代。 四 调查对象与问题 6. B。It includes students with different interests. 只问篮球社成员，答案更可能偏向篮球；B 比 A 更适合了解全校不同需要，但仍要看人数及选择方法，不能自动认定完全代表全校。 7. 示例：Which new after-school sports activity would you most like to join? Choose one. 若提供固定选项，宜保留 Other: ___，避免遗漏本校学生希望参加的项目。 教学提示：这一课既练英语，也练数学中的“数据从哪里来”。允许学生先用中文说明推理，再借助句架把核心判断说成英语。 参考图表与数据表达 五 绘图检查 8. bar。These are different activities, not points in a time sequence. 柱状图最方便直接比较人数；饼图也可显示各选择的份额，但本题给出的坐标更适合柱状图。不要把四个离散类别连成表示时间趋势的折线。 四根柱依次为 12、8、6、4；柱宽一致；纵轴从0开始，每格2人；标题、类别、人数单位齐全；12 + 8 + 6 + 4 = 30。 Activity Students What can be said Basketball 12 the most popular choice in this sample Table tennis 8 4 fewer than basketball Running 6 half the basketball number Dance 4 the least popular choice in this sample 六 建议示例 9. 参考表达，共47词： Among these 30 students, basketball was the most popular choice. Four more students chose basketball than table tennis. The school could try a basketball activity first. However, these students came from only one class, so we should ask students in other classes before making a school-wide decision. 也可以建议先试开两个项目，或保留较小项目的机会，只要与数据相符并说明理由。票数最多不自动等于全校一定应开设该社团，还需考虑已有活动、场地、师资和学生实际参与意愿。 10. 示例：Which sports activities do students in other classes want? / Do we have enough space and a teacher for the new activity? / Which day can interested students attend? 评价项目 达成表现 读取 区分类别、数值和单位；不把人数误当小时或百分比。 表示 根据问题选择图表；绘图数值准确、标注齐全。 推理 用数值支持比较；能发现重叠类别和样本范围的问题。 表达 建议与数据有关；清楚说明结论适用于谁。 选做调查只用于练习记录和表达，不与教材 Class 7B 或本学案30人数据混合。学生若发现同伴想选两个项目，应回到“每人选择一种”的规则，必要时另设开放问题记录补充意见。 第 页 共 页 学科网（北京）股份有限公司 $
