GRADE 8 · EXPERIENCE 1 · DIGITAL CONFIDENCE

Troubleshoot one variable at a time

Diagnose a simple file problem using a test log. · About 45 minutes

A symptom is what you observe; a cause is an explanation to test. Change one factor and compare results before making the next change.

A report opens in one app but not another. Check the file type, try the approved compatible app, and record the result before changing the file.

Follow the steps

Observe: Write the exact symptom.
Hypothesise: List a possible cause without calling it proven.
Test: Try one reversible, approved change.
Record: Keep the result and choose the next test.

Next challenge: Use the same method for a formatting problem.

GRADE 8 · EXPERIENCE 2 · CREATE AND COMMUNICATE

Disagree using reasons

Compare a proposal fairly and respond to its evidence. · About 45 minutes

Constructive disagreement addresses a claim and reasons, not the person. Restating another view can reveal misunderstandings.

One team favours a reading corner; another wants a game shelf. Both compare space, cost and access instead of judging each other.

Follow the steps

Listen: Restate the other proposal fairly.
Compare: Name shared criteria such as space and access.
Reason: Give evidence for your preferred option.
Revise: Change your view if stronger evidence appears.

Try these exercises

Which response supports a useful discussion?
A. Your idea is silly | B. Let us compare space and access for both options | C. Only my view matters
Answer: ______________________________________________
Which evidence would best show this skill?
A. Say it is finished without checking | B. Copy an unrelated answer | C. Represent the other view fairly and explain or demonstrate it
Answer: ______________________________________________
Put the worked-example steps in order.
Write the letters in order: A. Revise | B. Reason | C. Compare | D. Listen
Answer: ______________________________________________

Create, explain and reflect

Hold a role-play discussion about two classroom improvements. Record an agreed criterion and a revised idea.

My notes or drawing (use another sheet if needed):

___________________________________________________________

___________________________________________________________

□ Represent the other view fairly
□ Use relevant evidence
□ Avoid personal attacks

What did I learn or change? ___________________________________

Next challenge: Find a compromise that meets the shared goal.

GRADE 8 · EXPERIENCE 3 · DATA AND DECISIONS

Inspect a percentage claim

Check both numerator and denominator. · About 45 minutes

A percentage is a part divided by the whole, multiplied by 100. A large percentage can still come from a small sample.

In a fictional trial, 12 of 20 tasks succeeded. Success rate = 12 / 20 × 100 = 60%.

Follow the steps

Read: Read the labels and values: Succeeded: 12, Other: 8.
Represent: Compare the bars on a scale that starts at zero.
Calculate: Work through the calculation in the example; result: 60.
Interpret: Explain what the result means and what it does not establish.

Try these exercises

What percentage succeeded?
A. 62 | B. 59 | C. 60
Answer: ______________________________________________
Which evidence would best show this skill?
A. Copy an unrelated answer | B. Use the supplied values accurately and explain or demonstrate it | C. Say it is finished without checking
Answer: ______________________________________________
Put the worked-example steps in order.
Write the letters in order: A. Interpret | B. Calculate | C. Represent | D. Read
Answer: ______________________________________________

Create, explain and reflect

Represent the 12 successes and 8 other outcomes. Write the percentage and sample size together.

My notes or drawing (use another sheet if needed):

___________________________________________________________

___________________________________________________________

□ Use the supplied values accurately
□ Show a calculation or count with its meaning
□ State a fair comparison or limitation

What did I learn or change? ___________________________________

Next challenge: Compare 3 of 5 with 12 of 20 without claiming equal certainty.

GRADE 8 · EXPERIENCE 4 · COMPUTATIONAL THINKING

Accumulate a list total

Trace a loop that updates an accumulator. · About 45 minutes

An accumulator stores a running result. Initialise it before the loop, then update it once per item.

Start total = 0. For values 2, 4, 6, add each once: totals 0, 2, 6, 12.

Follow the steps

Initialise: total = 0.
Item 1: Add 2; total = 2.
Item 2: Add 4; total = 6.
Item 3: Add 6; total = 12.

Try these exercises

What is the final total?
A. 24 | B. 6 | C. 12
Answer: ______________________________________________
Which evidence would best show this skill?
A. Initialise the accumulator and explain or demonstrate it | B. Say it is finished without checking | C. Copy an unrelated answer
Answer: ______________________________________________
Put the worked-example steps in order.
Write the letters in order: A. Item 3 | B. Item 2 | C. Item 1 | D. Initialise
Answer: ______________________________________________

Create, explain and reflect

Make a trace table for the list and for an empty list. Explain the initial value.

My notes or drawing (use another sheet if needed):

___________________________________________________________

___________________________________________________________

□ Initialise the accumulator
□ Update once per item
□ Test an empty input

What did I learn or change? ___________________________________

Next challenge: Adapt the trace to count only values above 3.

GRADE 8 · EXPERIENCE 5 · RESPONSIBLE TECHNOLOGY

Minimise data in a form

Collect only information needed for a stated purpose. · About 45 minutes

A form should have a clear purpose. More data is not automatically better; unnecessary personal information creates avoidable exposure.

A fictional classroom activity poll needs an activity choice. It does not need a home address or a personal photograph.

Follow the steps

Purpose: Choose an activity for the class.
Review: Inspect proposed fields: choice, address, photo.
Minimise: Keep the choice; remove unnecessary private fields.
Explain: State who uses the responses and for how long.

Try these exercises

Which field is unnecessary for an anonymous activity vote?
A. Activity choice | B. Home address | C. An optional activity suggestion
Answer: ______________________________________________
Which evidence would best show this skill?
A. Say it is finished without checking | B. Copy an unrelated answer | C. Match fields to purpose and explain or demonstrate it
Answer: ______________________________________________
Put the worked-example steps in order.
Write the letters in order: A. Explain | B. Minimise | C. Review | D. Purpose
Answer: ______________________________________________

Create, explain and reflect

Redesign a fictional poll and write a purpose, access and deletion plan. Do not collect real responses.

My notes or drawing (use another sheet if needed):

___________________________________________________________

___________________________________________________________

□ Match fields to purpose
□ Remove unnecessary personal data
□ Explain access and retention

What did I learn or change? ___________________________________

Next challenge: Consider whether even optional free text could reveal private details.

GRADE 8 · EXPERIENCE 6 · DESIGN AND LIFE SKILLS

Choose between competing designs

Compare alternatives against explicit criteria. · About 45 minutes

A design can be strong on one criterion and weak on another. A decision needs reasons and may involve trade-offs.

A folded stand is stable but uses more paper. A flat sign uses less paper but needs support. Compare both for the intended use.

Follow the steps

List: Choose two plausible designs.
Criteria: Agree stability, readability and material use.
Compare: Record evidence for each design.
Choose: Explain the trade-off and a next test.

Try these exercises

What makes the comparison fairer?
A. Applying the same relevant criteria | B. Hiding a weakness | C. Using different rules for each option
Answer: ______________________________________________
Which evidence would best show this skill?
A. Copy an unrelated answer | B. Apply the same criteria and explain or demonstrate it | C. Say it is finished without checking
Answer: ______________________________________________
Put the worked-example steps in order.
Write the letters in order: A. Choose | B. Compare | C. Criteria | D. List
Answer: ______________________________________________

Create, explain and reflect

Create a comparison table for two paper sign designs, then choose one for a stated setting.

My notes or drawing (use another sheet if needed):

___________________________________________________________

___________________________________________________________

□ Apply the same criteria
□ Use observations rather than preference alone
□ Explain a trade-off

What did I learn or change? ___________________________________

Next challenge: Change the setting and reconsider the choice.

Keep the learning going

Choose one work sample, explain an improvement, and name the next skill to practise.
