    1 - Introduction ~5 mins

    Welcome

    Today you bank Specialism Module 3 Key Assignment 2. You will turn real project numbers into at least two different charts, write a plain-English interpretation under each one, and export a clean named PDF for your portfolio. Same idea as showing a boss or customer, in thirty seconds, which week made money and where costs ate profit.

    Open this first: Open {{code:sm3_ka1_problem_solver.xlsx}} (or your Google Sheet version) from {{code:09_specialism/sm3}}, or any clean project numbers you already have. If you cannot open a file with usable numbers, put your hand up now so your teacher can set a fallback before the quality talk starts.

    If you do not have KA1 data yet: You can still practise the KA2 pattern today. Your teacher will approve a dual-table mini dataset on a fresh sheet: Table A with at least four values in a series (for example four weeks of attendance, sales, or hours) for a column or line chart, and Table B with at least three category amounts that make up a whole (for example materials, fees, travel) for a pie chart. Copy both small tables into your new chart workbook. Final banking still prefers real Something Real project data when it is ready; ask your teacher to initial the fallback source.

    By the end of this lesson, you will be able to:

    • Represent project data with at least two different charts
    • Write clear interpretations a non-technical reader can understand
    • Bank Specialism Module 3 Key Assignment 2 and complete the Module 3 reflection

    Warm-up

    With your numbers on screen: if a supervisor, examiner, boss, or sponsor only had thirty seconds, which pattern should they see first: a trend over time, a comparison between categories, or a share of a total?

    2 - Key Concepts ~6 mins

    Key point

    KA2 is not just "make two charts". The SEC needs charts that fit the data and interpretations a non-technical reader can act on. Think boss or customer, not decoration.

    • Right chart for the question — trend or comparison suits a column or line chart; share of a total suits a pie or doughnut
    • Two different chart types — variety, not two copies of the same visual
    • Four-part write-up under each chart — overall trend, biggest value, smallest value, one decision
    • Named PDF export — save {{code:sm3_ka2_charts.pdf}} beside the workbook so evidence stays stable off-screen

    Four-part pattern (watch your teacher tick these on a sample chart)

    1. Trend: what is going up, down, or staying steady?
    2. Biggest value: name it and the number
    3. Smallest value: name it and the number
    4. Decision: one action a reader could take
    Example

    Model shape: Revenue rises overall across 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.

    VET in this course means the Vocational Education Task pack: a place where strong spreadsheet and chart evidence can be reused later, alongside Work Experience and other LCA work.

    In the next activity your teacher builds the first market-stall chart live. You then complete the second chart, both write-ups if needed, and a PDF using the same quality bar. Your own KA2 workbook must reach that standard with your project data.

    3 - Step-by-step Task ~15 mins

    Build a worked-example chart workbook for a small market-stall project. Your teacher completes the first chart (column + four-part interpretation) live on the board. You enter or finish the cost data, build the pie chart, write its interpretation, and export a named PDF. That is the quality bar for your own KA2 evidence next.

    Tip

    If the first chart takes longer than expected, that is normal. Nail the column chart and its four-part note first; the pie chart reuses the same pattern.

    4 - Common Issues ~4 mins

    Common Issues

    IssueSolution
    My chart is plotting the wrong columnsSelect only the labels and the value column you want. If extra columns are included, delete the chart and select the range again before inserting a new one.
    Both of my charts are the same typeKA2 needs two different chart types. Keep one comparison or trend chart (column or line) and pair it with a composition chart (pie or doughnut) or another clearly different type that fits the second question.
    My interpretation just describes colours or layoutRewrite it using the four-part pattern: overall trend, biggest value, smallest value, and one decision a reader could act on.
    The PDF cuts off the chart or looks tinyUse print preview first. Switch to landscape if the chart is wide, set the print area to the chart and interpretation only, and scale to fit one page. Save as {{code:sm3_ka2_charts.pdf}} (or {{code:sm3_ka2_worked_example.pdf}} for the practice file), not Untitled.
    I do not know which project data to use / my KA1 file is missing or messyPrefer {{code:sm3_ka1_problem_solver}} or any clean project dataset already in {{code:sm3/}}. If that file is missing or messy, ask your teacher for a dual-table fallback on a fresh sheet: Table A with at least four series values (weeks, days, or categories) for a column or line chart, and Table B with at least three category amounts for a pie chart. Do not use three loose cells alone — you need two chartable shapes. Ask your teacher to initial the alternate source so KA2 can still proceed today.

    5 - Portfolio Build ~20 mins

    Portfolio Build: Bank KA2

    Your goal: Produce bankable SM3 KA2 evidence that turns your Something Real project numbers into two clear charts with plain-English interpretations a supervisor or examiner can trust. Use your worked example as the quality bar, not as something to retype. Swap in your real project numbers and keep the same layout.
    Time: ~20 minutes
    Task: Work in this order. Priority 1 must be finished in class so KA2 can land today; Priority 2 can finish in a short supervised catch-up if your charts and PDF are already bankable.
    1. Open data: Open {{code:Project_Portfolio/09_specialism/sm3}} and your KA1 problem-solver sheet (or a closely related clean dataset). If KA1 is missing or messy, use a teacher-approved dual-table fallback on a fresh sheet: Table A with at least four series values (for a column or line chart) and Table B with at least three category amounts (for a pie chart). Ask your teacher to initial that source. Three loose numbers alone are not enough for two different chart types.
    2. Create the workbook: Excel Online: {{code:sm3_ka2_chart_workbook.xlsx}}. Google Sheets: {{code:sm3_ka2_chart_workbook}} (no extension needed).
    3. Two charts: Build at least two different chart types, each with a clear title that fits the question the data answers (one trend/comparison chart from Table A or equivalent, one composition chart from Table B or equivalent).
    4. Interpretations: Write a four-part interpretation under each chart (trend, biggest, smallest, one decision).
    5. Named PDF: Export the charts (one combined file is fine) as {{code:sm3_ka2_charts.pdf}} into the same {{code:sm3}} folder.
    6. Module 3 reflection (Priority 2): In the same folder create Word Online {{code:sm3_module3_reflection.docx}} or Google Doc {{code:sm3_module3_reflection}}. Use three headings with starters: What improved most… (name a real spreadsheet skill such as non-adjacent chart ranges, four-part interpretation, or PDF export); Chart I will reuse… (which chart and why a boss or customer would care); Skill for Work Experience, another LCA course, or the VET pack… (one concrete next use). One or two sentences under each heading is enough.
    7. Show your teacher: When Priority 1 is ready, show the workbook and {{code:sm3_ka2_charts.pdf}} for KA2 check. Bring KA1 if it still needs sign-off. Reflection can be verified as soon as it is specific.
    Success criteria:
    • {{code:sm3_ka2_chart_workbook}} (Excel .xlsx or Google Sheet) sits in {{code:09_specialism/sm3}} and uses real Something Real project data, or a teacher-initialled dual-table fallback (4+ series values plus 3+ category shares)
    • The workbook contains at least two different chart types, each with a clear title and a four-part written interpretation
    • {{code:sm3_ka2_charts.pdf}} is saved beside the workbook (not Untitled or a random download name)
    • {{code:sm3_module3_reflection}} names a real spreadsheet skill and one real next use (Work Experience log, VET pack, or another LCA subject), not just "charts are useful", and your teacher has a path to check SM3 KA1 and KA2
