Understand Scale NotationSEAG Practice Questions

Understanding what scale notation means (e.g., 1:100 means 1 cm on the drawing represents 100 cm in real life).

Where your child meets this in real life: Understanding map scales, model kit scales, or architect drawings

What your child needs to know

SEAGReady breaks understand scale notation into 2 steps, taught in order so each skill builds on the last.

  1. 1

    Reading Scale Notation

    Understand what scale notation 1:n means and identify what each number represents

  2. 2

    Size Relationships

    supporting lesson — excluded from official-format mocks

    Understand that the drawing is smaller than real life and compare different scales

Three free sample questions from our understand scale notation course. Every question comes with a full explanation, and hints that guide without giving the answer away.

Question 1Confidence builder

The garden-map information is shown. How long is the path in real life?

A garden path is 1 cm on a map with scale 1 to 100; its real length in centimetres is unknown.
Answer choices for question 1
Question 2Confidence builder

Noah has the two model kits shown for the same aeroplane. Which labelled scale gives the larger model?

Two models of the same aeroplane use scales 1 to 48 and 1 to 72; their drawn panels are schematic.
Answer choices for question 2
Question 3Confidence builder

Poppy is reading a floor plan with a scale of 1:50. What does the second number represent?

Try the lesson: Reading Scale Notation

This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.

Ellie is looking at a simple plan of a school garden. The plan has a scale of 1:200.

If a path is 1 cm long on the plan, how many cm is it in real life?

1:200

Identify what each number means
1

The first number (1) represents the drawing

Ellie is looking at a simple plan of a school garden. The plan has a scale of 1:200.

If a path is 1 cm long on the plan, how many cm is it in real life?

  1. 1

    Identify what each number means

    • The first number (1) represents the drawing
    • The second number (200) represents real life
  2. 2

    Apply the scale

    • 1 cm on the plan = 200 cm in real life
    • So the path is 200 cm in real life1 cm → 200 cm

The path is 200 cm in real life.

The key insight: In a scale like 1:200, the first number is the drawing and the second is real life when both use the same unit.

Common mix-up: Thinking 1:200 means the drawing is 200 times as long as real life. The drawing is one two-hundredth of the real length.

Mistakes to watch for

These are the misconceptions we see most often in understand scale notation, including the ones our practice questions are specifically designed to catch.

  • Thinking 1:100 means the drawing is 100 times bigger than real life
  • Confusing which number represents the drawing vs real life
  • Not understanding that both numbers use the same unit
