Zero tenths hold the place

What this lesson shows

Fixes a mistake

Sixty-seven and three hundredths is 67.03, not 67.3.

The worked example

The lesson works this one step by step: 67.03 in digits. Then your kid tries one like it on paper.

The steps

  1. The last word names the place
  2. A 0 holds the empty place
  3. Read it back

Helping at home

The last word of a decimal names the place of its last digit. Put that digit there, and write a 0 in any empty place between it and the point.
