Dive under the sea with this happy little fish! In this color by number activity for kids, every area of the picture has a small number inside it. Each number stands for one colour, so a 1 is always orange and a 4 is always green. Children look at the colour key, find the matching number and fill the space with the right shade.

It is a calm, screen-friendly activity for preschool and early primary children. Colour it online or print it free and use crayons, pencils or sketch pens at home or in class.

How to play

  1. Look at the colour key and read each number with its colour, such as 1 for orange and 2 for blue.
  2. Find an area on the fish picture and read the number printed inside it.
  3. Fill that whole area with the matching colour, staying inside the lines.
  4. Keep going until every numbered space is coloured, then enjoy your bright underwater scene.

Colour by number gives young children lots of quiet learning in one simple activity. Your child practises number recognition from 1 to 8, matches a symbol to a colour, and remembers the rule while working across the page. Holding a crayon and colouring inside the outlines strengthens the small hand muscles needed for writing. Completing one area at a time also builds patience, concentration and the confidence that comes from finishing a task. Sit with your child for the first few areas, say the numbers and colour names aloud together, then let them carry on independently and talk about the finished picture.

Frequently asked questions

What age is this colour by number suitable for?
It works best for children aged four to six who can recognise numbers one to eight. Younger children of three can join in with help, while older kids often finish it quickly on their own and enjoy adding their own background details.
Can I print this fish activity for free?
Yes. The fish colour by number worksheet is completely free to print at home or in school. Use plain A4 paper, print as many copies as you need, and let children colour with crayons, colour pencils or washable sketch pens.
What if my child uses a different colour than the key?
That is absolutely fine. The aim is enjoyment and number practice, not perfection. Gently point to the key and read the number together, but let your child's choices stand if they are happy with their own colourful fish.
How does colour by number help with learning?
It links numbers to a clear action, so children read, decide and colour in one smooth step. This builds number recognition, colour naming, concentration and pencil control, all of which support early reading, writing and maths readiness.
