scale drawing

Definition

A scale drawing is a picture where everything is made smaller or larger by the same amount, so it still looks like the original but fits on paper or is easier to see.

A blueprint where 1 centimeter on the drawing represents 1 meter of the actual building is a scale drawing.

How to teach this in 30 seconds

Try this analogy: A scale drawing is like a map on your phone, where a one-inch line might represent a real-life mile, keeping everything perfectly in proportion.

Ask your child: If we made a scale drawing of this room, what measurement would we need first?

Common mix-up: Students may think a scale drawing is just any smaller sketch. The key is that every part of the object is shrunk or enlarged by the exact same factor, so nothing is distorted.

Examples

  • A road map where one inch equals five miles.
  • A diagram of an insect in a science book that is enlarged 10 times its actual size.
  • The floor plan for a new house showing the layout of the rooms.

scale drawing is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
