Taller, longer, heavier.
The big ideaLine them up, or use a balance. Then see which has more.

How it works

Line them up, or use a balance. Then see which has more.

To compare length, start both at the same line.

The heavier one pushes the balance down.

Compare two things.

  2. One goes down.
  3. That one is heavier.
