Fish Color by Number Activity
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
- Look at the colour key and read each number with its colour, such as 1 for orange and 2 for blue.
- Find an area on the fish picture and read the number printed inside it.
- Fill that whole area with the matching colour, staying inside the lines.
- 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.
