    Warm-up

    A boss has thirty seconds to look at your chart. Should it show a change over time, a comparison, or a share of a total?

    2 - Key Concepts ~6 mins

    A column or line chart shows change over time, like sales each week.

    A pie chart shows how a total is split, like where your money went.

    You need two different chart types, not two of the same.

    An interpretation is a short note under a chart. It names the trend, the biggest value, the smallest value and one decision.

    Example

    Revenue rises over six weeks. Week 6 is biggest at €330 and week 3 is smallest at €120. Decision: order extra stock for the last market.

    3 - Step-by-step Task ~15 mins

    You will make a practice workbook for a small market stall, with a column chart and a pie chart. Your teacher makes the first chart live. Then you make the pie chart and the PDF. Follow the steps in the box below, and copy the tables and notes from these boxes.

    Sales_trend

    WeekUnits soldRevenue (€)
    Week 130150
    Week 236180
    Week 324120
    Week 442210
    Week 552260
    Week 666330

    Cost_share

    CostAmount (€)
    Materials420
    Stall fees160
    Travel90
    Marketing45

    Model note 1 (column chart): Revenue rises overall across the six weeks. The biggest week is week 6 at €330. The smallest is week 3 at €120. Decision: order extra cases for the final market weekend and check what slowed week 3.

    Model note 2 (pie chart): Materials dominate the costs at €420. Marketing is the smallest cost at €45. Stall fees and travel together are still smaller than materials alone. Decision: negotiate bulk materials pricing before the next market block.

    4 - Common Issues ~4 mins

    Common issues

    • The chart shows the wrong columns. Delete it, select only the columns you need, and try again.
    • Both charts are the same type. Change one of them to a pie chart.
    • My note only talks about colours. Use the four parts: trend, biggest, smallest and one decision.
    • The PDF cuts off the chart. Switch to Landscape and fit it to one page.

    5 - Portfolio Build ~20 mins

    Key Assignment 2: your chart workbook

    Your goal: Make two different charts from your own project numbers.
    Time: ~20 minutes
    Task:
    1. In {{code:sm3}}, make a workbook called {{code:sm3_ka2_chart_workbook}}.
    2. Copy in your numbers from {{code:sm3_ka1_problem_solver}}.
    3. Make two different charts, each with a title.
    4. Under each chart, write a note with the trend, biggest, smallest and a decision.
    5. Save as {{code:sm3_ka2_charts.pdf}}, upload it to {{code:sm3}}, then show your teacher.

    No numbers, or too few for two charts? Use the hours in {{code:sm3_time_tracker}} and the costs in {{code:sm3_from_template}}, and ask your teacher to initial them.

    Then make a document in {{code:sm3}} called {{code:sm3_module3_reflection}} with the headings below.

    Chart I will reuse, and why:

    Where I will use this skill next (Work Experience or another LCA subject):

    Success criteria:
    • My workbook uses my own numbers.
    • It has two different charts.
    • Each chart has a title and a four-part note.
    • My PDF is saved in {{code:sm3}}.
