What is a practice skill?

A practice skill is a focused topic or question type designed to help students practise one curriculum-aligned concept with instant feedback and explanations. Skill Align uses practice skills to organise questions by year level, subject, strand, and curriculum focus.

Sample Year 8 Maths questions

These sample questions are visible on the page before login. They show Year 8 scale, linear relationships, Pythagoras, rates, probability, and algebra explanations before opening the demo.

Year 8 Maths Scale and measurement hard scale plan

1. A map has scale 1:25,000. The distance between two points is 8.4 cm on the map. What is the actual distance in kilometres?

Map scale distance 8.4 1 S
Choices
  • 2.1 km
  • 0.21 km
  • 21 km
  • 1.68 km
Explanation:

The actual distance is 8.4 × 25,000 = 210,000 cm. Since 100,000 cm = 1 km, this is 2.1 km.

Year 8 Maths Linear relationships hard break-even graph

2. A straight line passes through (2, 7) and (6, 19). Which rule gives the line?

Line through two points P Q m
Choices
  • y = 3x + 1
  • y = 4x - 1
  • y = 3x - 1
  • y = x + 5
Explanation:

The gradient is (19 - 7) / (6 - 2) = 3. Using (2, 7), 7 = 3 × 2 + b, so b = 1. The rule is y = 3x + 1.

Year 8 Maths Pythagoras and geometry hard diagram

3. A ramp is 5.2 m long and its horizontal run is 4.8 m. What is the vertical rise of the ramp?

Right-triangle ramp 4.8 m h
Choices
  • 2.0 m
  • 1.4 m
  • 3.2 m
  • 10.0 m
Explanation:

Use Pythagoras: rise² = 5.2² - 4.8² = 27.04 - 23.04 = 4. The rise is 2.0 m.

Year 8 Maths Rates and equations hard growth graph

4. A tank already contains 40 L of water and fills at 18 L per minute. After how many minutes will it contain 220 L?

Linear filling model t V n 220
Choices
  • 10 min
  • 12.2 min
  • 14.4 min
  • 180 min
Explanation:

The added water must be 220 - 40 = 180 L. At 18 L per minute, the time is 180 / 18 = 10 minutes.

Year 8 Maths Probability hard probability tree

5. P(rain) = 0.35. If it rains, P(late) = 0.60; if it does not rain, P(late) = 0.15. What is the probability of being late?

Rain and lateness tree R N L
Choices
  • 0.3075
  • 0.21
  • 0.45
  • 0.7475
Explanation:

Add the late branches: 0.35 × 0.60 + 0.65 × 0.15 = 0.21 + 0.0975 = 0.3075.

Year 8 Maths Algebra and area hard scale plan

6. A large square has side length 3x and a small square has side length x. The difference between their areas is 128 cm². What is x?

Difference of square areas 3x x A
Choices
  • 4
  • 8
  • 16
  • 2
Explanation:

The area difference is (3x)² - x² = 9x² - x² = 8x². So 8x² = 128, x² = 16, and x = 4 because a side length is positive.

For parents comparing Year 8 Maths support

Year 8 maths practice should make proportional reasoning, linear rules, Pythagoras, rates, probability, and algebra feel structured rather than guessable. These examples preview that style before the no-login Year 8 Maths demo.

What this practice and exercise page covers

Australian Curriculum-aligned maths coverage across number, algebra, measurement, space, statistics, and probability, with structured sample questions available through the Year 8 maths demo.

Practice sessions include exercise mode for instant feedback, test mode for delayed results, and parent review when the student signs in through a managed account. Skill Align treats practice questions and exercise questions as the same learning workflow: students answer curriculum-aligned questions, review explanations, and move between exercise mode and test mode.

Start with the public sample questions to check the question style, then use the curriculum coverage page to choose a topic that matches the student's current classwork.

Preview question styles
  • Ratio and proportion: A short calculation item asks students to compare quantities and choose the equivalent ratio with a worked explanation.
  • Linear relationships: A table or coordinate pattern item checks whether students can identify a rule and connect it to the matching graph or equation.
  • Measurement and data: A practical area, volume, or statistics item focuses on the information needed to solve the problem without decorative diagrams.
Suggested first practice steps
  • Preview the public sample practice and exercise questions before creating a saved student session.
  • Choose one focus area that has already been introduced at school.
  • Use exercise mode for immediate explanations, then test mode when the student is ready for delayed feedback.

These examples are not the full topic list. Use the curriculum coverage page for the complete mapped pathway.

  • Fractions, decimals and ratios
  • Linear relationships and equations
  • Area, volume and geometry
  • Statistics, probability and data interpretation
