What your child needs to know

In the SEAG test

Each SEAG paper has 28 maths questions. Questions 29 to 50 are multiple choice with five possible answers, and questions 51 to 56 need a short written answer. With 56 questions in 60 minutes across English and maths, that is about a minute per question.

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

  1. 1

    Powers of Ten Scales

    Read measurements from scale drawings using scales of 1:10, 1:100, or 1:1000 and state the real-life length

  2. 2

    Other Common Scales

    Read measurements from scale drawings using scales like 1:20, 1:25, 1:50, or 1:200

Try these SEAG-style questions

Try three free questions from our read scale drawings course. They start easy and get harder, so you can see where your child's confidence runs out. If they manage the last one without a hint, this topic is probably secure. If not, the steps above show where to start.

Question 1Confidence builder

Lily uses the floor plan shown. What is the real length of the living room?

A plan segment for a living room is labelled 5 cm and has scale 1 to 100.
Answer choices for question 1
Question 2Standard

Emily uses the bridge drawing shown. What is the real length of the main span?

A main bridge span on a drawing is labelled 9 cm and has scale 1 to 200.
Answer choices for question 2
Question 3Stretch

Poppy uses the museum floor plan shown. How long is the main exhibition hall in metres?

A main exhibition hall on a floor plan is labelled 6 cm and has scale 1 to 1000.
Answer choices for question 3

Try the lesson: Powers of Ten Scales

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

Jessica is looking at a floor plan of her school. The scale on the plan is 1:100. She measures the corridor and finds it is 8 cm on the plan.

What is the real length of the corridor?

8 cm × 100

Understand what the scale means
1

Scale 1:100 means 1 cm on the drawing is 100 cm in real life

Jessica is looking at a floor plan of her school. The scale on the plan is 1:100. She measures the corridor and finds it is 8 cm on the plan.

What is the real length of the corridor?

  1. 1

    Understand what the scale means

    • Scale 1:100 means 1 cm on the drawing is 100 cm in real life
  2. 2

    Calculate the real length

    • Drawing measurement is 8 cm
    • Multiply by the scale factor8 × 100 = 800 cm

The real corridor is 800 cm long.

The key insight: Multiply by the stated power of ten. With whole-number measurements, multiplying by 100 may look like appending two zeros.

Common mix-up: 8 ÷ 100 = 0.08 cm. Real life is BIGGER than the drawing, so we multiply, not divide.

Mistakes to watch for

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

  • Not using the ruler correctly to measure
  • Reporting the measured length instead of the real-life length
  • Forgetting to convert units when needed

Build these skills first

Struggling with read scale drawings? The real gap is often in one of these earlier topics.
