Pixel Colour-by-Number 8x8 (Blank)
8x8 grid plus a number-to-colour key to design your own.
This blank 8x8 pixel colour-by-number template lets students design their own colour-coded puzzle from the ground up. The sheet includes an 8x8 grid of large, easy-to-fill cells plus a number-to-colour key section where the creator assigns a number to each colour they plan to use. Once filled in, the completed sheet becomes a puzzle another student can solve. Perfect for kindergarten through grade 6, the big cell size suits young learners still developing fine-motor skills. Teachers use it as a creative twist on traditional colour-by-number activities — instead of solving one, students make one. It doubles as an introduction to simple coding logic (assign a value, follow the rule) and works equally well in class centres, early-finisher bins, or at home.
Learning objectives
- Create an original colour-by-number puzzle using a self-designed key
- Practise one-to-one correspondence between symbols and colours
- Develop early coding and rule-based thinking
- Strengthen fine-motor skills through large-cell colouring
- Encourage creative decision-making in a structured format
- Build confidence in sharing and explaining a self-made activity
How to use this template
- Download the free printable and print one copy as your design sheet.
- Decide on up to 9 colours and write each colour next to a number in the key section.
- Fill each cell of the 8x8 grid with the corresponding number (pencil first, then confirm).
- Colour your own grid to create the answer key, then print a fresh blank copy for a friend to solve.
- Exchange puzzles with a classmate and solve each other's colour-by-number design.
Classroom & home ideas
- Set up a puzzle-swap station where students complete a design sheet, then pass it to the next student to colour.
- Use as a maths warm-up: after solving, count the cells of each colour and record the tally in a bar chart.
- Make a seasonal class book — every student designs a holiday-themed 8x8 puzzle and the class binds them into a solvable collection.
- Introduce the activity as an analogy for computer instructions: the number key is the code; the grid is the output.
- Send home as a family activity — children design a puzzle for a parent or sibling to solve at dinner.

Frequently asked questions
How many colours can be used in the 8x8 version?
The key section supports up to 9 numbered colours, which is plenty for a simple 8x8 design. Younger students often use just 2–4 colours to keep it manageable.
Is this suitable for kindergarten?
Yes. The large cells are sized for early-childhood fine-motor skills. Teachers may guide kindergarteners through filling in the key together as a class before students choose their own cell numbers.
Can the template be used digitally on a tablet?
The PDF can be imported into drawing apps like Notability or GoodNotes and filled in with a stylus, making it suitable for one-to-one device classrooms.
What is the difference between this and a pre-made colour-by-number sheet?
A pre-made sheet gives students a puzzle to solve. This blank template puts students in the creator role — they design the image, write the key, and produce a puzzle for someone else, adding a deeper layer of thinking.
