One Thing at a Time — Class 4 English (CBSE)

From the current Class 4 English Santoor textbook, Unit 2: My Beautiful World, Chapter 4. A short, wise poem about doing things one at a time and doing them well.


1. Chapter at a glance

  • Text type: A rhyming poem with a moral.
  • Main theme: Focus — do one thing at a time, with full effort.
  • What to notice while reading: The advice to separate work and play and to give your best.

2. The Poem

One thing at a time,
And that done well,
Is a very good rule,
As many can tell.

Work while you work,
Play while you play;
That is the way
To be happy each day.

All that you do,
Do with your might;
Things done by halves
Are never done right.

3. Summary

The poem gives simple, wise advice: do one thing at a time and do it well. When you work, only work; when you play, enjoy playing. Put your full effort into everything, because tasks done half-heartedly are never done properly. Focusing on one task at a time helps us finish well and feel happy and proud.

4. Theme and values

  • Focus — give all your attention to one task.
  • Doing your best — "do with your might".
  • Balance — a time for work and a time for play.
  • Happiness through good work — finishing well brings joy.

  3. What does "do with your might" mean? Do everything with your full strength and effort.
