Read or watch the example, try three questions, make the project and reflect. Roughly half the session is for creating and explaining. Take breaks and adapt reading support.

All examples are fictional. Use approved tools and adult support where indicated. Project checkboxes are self-review, not automatic assessment or certification.

Review levels

With support: completes with prompts. Independently: meets the criteria and explains a choice. Transfer: applies the skill in a new setting with evidence.

GRADE 8 · EXPERIENCE 1 · DIGITAL CONFIDENCE

Troubleshoot one variable at a time

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

Answers and reasons

B. It makes causes easier to identify
You can connect the observed difference to the factor you changed.
A. Separate symptom from cause and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Observe → Hypothesise → Test → Record
The example follows: Observe → Hypothesise → Test → Record. Explain what each step does.

Project evidence to review

Investigate a fictional file-opening problem. Create a symptom, hypothesis, test and result table.

Separate symptom from cause
Change one factor per test
Record unsuccessful tests honestly

Teaching guidance

Do not disable security tools or install unknown software to solve the exercise.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

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

Answers and reasons

B. Let us compare space and access for both options
Shared criteria focus discussion on the proposals.
C. Represent the other view fairly and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Listen → Compare → Reason → Revise
The example follows: Listen → Compare → Reason → Revise. Explain what each step does.

Project evidence to review

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

Represent the other view fairly
Use relevant evidence
Avoid personal attacks

Teaching guidance

Do not require a learner to disclose a personal conflict.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

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

Answers and reasons

C. 60
Use the given numbers: the answer is 60. Explain your counting or calculation.
B. Use the supplied values accurately and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Read → Represent → Calculate → Interpret
The example follows: Read → Represent → Calculate → Interpret. Explain what each step does.

Project evidence to review

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

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

Teaching guidance

Ask the learner to show intermediate work. Use fictional data; no real pupil records are needed.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

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

Answers and reasons

C. 12
2 + 4 + 6 = 12; each item is added once.
A. Initialise the accumulator and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Initialise → Item 1 → Item 2 → Item 3
The example follows: Initialise → Item 1 → Item 2 → Item 3. Explain what each step does.

Project evidence to review

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

Initialise the accumulator
Update once per item
Test an empty input

Teaching guidance

Trace before testing. These are learning models and pseudocode, not instructions to run arbitrary downloaded code.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

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

Answers and reasons

B. Home address
An address does not help decide an activity.
C. Match fields to purpose and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
Purpose → Review → Minimise → Explain
The example follows: Purpose → Review → Minimise → Explain. Explain what each step does.

Project evidence to review

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

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

Teaching guidance

This is a design exercise, not legal advice or an actual data collection.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.

Transfer prompt

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

Answers and reasons

A. Applying the same relevant criteria
Shared criteria support a transparent comparison.
B. Apply the same criteria and explain or demonstrate it
Show the actual work or action described by the lesson criterion. An adult or partner can review it.
List → Criteria → Compare → Choose
The example follows: List → Criteria → Compare → Choose. Explain what each step does.

Project evidence to review

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

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

Teaching guidance

A decision can be reasonable without one design winning every criterion.

Model one step, invite the learner to try the next, then ask for an explanation. Accept a spoken or drawn answer when it demonstrates the skill.
