An individual Maths Fair item in which a student draws and presents a chart that shows a number idea, scored out of 100 at all four school levels.
A Number Chart is a hand-made chart that shows a number idea visually: a pattern in the multiplication table, the sieve of Eratosthenes, place value, magic squares, prime numbers, Pascal’s triangle or a number sequence. It is judged for the mathematics shown and for how well the student explains it.
In the The Kerala School Sasthrolsavam Mathematics Fair (Ganithashastramela) it is an individual item open to girls and boys at Lower Primary, Upper Primary, High School and Higher Secondary/VHSE. The same evaluation table is shared with Geometrical Chart and Other Chart.
A strong chart has one clear idea, accurate numbers, tidy lettering and a short write-up that links it to the textbook. At the exhibit the student explains the chart and answers questions, which is why exhibition carries 10 marks.
Because every level can enter, the difficulty of the idea should match the class: counting patterns for the youngest, number theory for the oldest.
Where Number Chart is run
This item is part of the official Kerala School Sasthrolsavam Mathematics Fair, the state school mathematics exhibition that runs from school level through sub-district, district and state rounds, and is installed on eTalenter through the Maths Fair template built from the official item list and evaluation indicators. This page describes the Kerala format only.

What judges look at in Number Chart
What a Number Chart panel is actually weighing up, and where the marks are usually won or lost:
- Knowledge of content and mathematical value (30): is the idea correct and worth showing?
- Relationship with the curriculum (20): does it connect to what the class is learning?
- Mode of presentation and write-up (25): clear layout and a good explanatory note.
- Beauty and perfection (15): neat lettering, accurate numbers and a clean finish.
- Exhibition (10): how well the student speaks about and handles the chart.
Treat these as the judging focus, not a fixed rubric: publish your own weighted criteria for Number Chart under Scoring Setup, or start from the judging and scoring software guide.
How to prepare for Number Chart
How entrants and their teachers usually get Number Chart right on the day:
- Pick one number pattern and write it as the heading.
- Draw the grid or layout lightly in pencil before inking.
- Check every number twice, then have a teacher check again.
- Write a five-line note explaining the pattern and how to use it.
- Choose a size and colour scheme that can be read from two metres.
- Practise a one-minute explanation and two questions you expect.
- Carry spare markers and a ruler for touch-ups.
- Idea to try: the sieve of Eratosthenes up to 100 with primes coloured
- Idea to try: patterns in the nine times table on a hundred-square
- Idea to try: Pascal’s triangle with the sums of rows and the powers of two

Frequently asked questions
Is Number Chart judged individually or as a team?
Across eTalenter’s templates it’s most often run as an Individual entry, though an organiser can set either participation type when assigning the item to an age group.
Is a write-up compulsory?
The marking table gives 25 marks to presentation and write-up, so yes, include one.
How is a Number Chart different from Other Chart?
A Number Chart shows number ideas; Other Chart covers other mathematical topics. Both use the same table.
Can Lower Primary pupils enter?
Yes, it is open at all four levels.
Can I copy a chart from the internet?
Marks reward understanding and your own work, and judges question the student, so be ready to explain it.
