Age 9 · Grade 4 · Year 5 · Class 4
Maths, coding and Rubik's Cube for 9-year-olds.
Nine-year-olds can follow a multi-step method and are ready for projects that take a few sessions.
Maths
Four-digit numbers, long multiplication and division, equivalent fractions and decimals, angles, area and perimeter, bar charts.
Coding
Python basics: print, variables, for loops and if statements, using short programs that can be changed.
Rubik's Cube
The 3×3 seven-step method. Aim to solve it without help, then try timing a solve.
A good first goal
Solving a 3×3 on their own, and writing a first program that uses a loop.
A simple week
About 15 to 20 minutes a day. Here is one way to spread it:
| Day | What to do |
|---|---|
| Mon | Fractions or decimals practice |
| Wed | Python program: change one line |
| Thu | Mental maths sprint |
| Sat | Cube practice or a timed solve |

Age 9: questions parents ask
Why do fractions suddenly get harder at nine?
Fractions ask a child to think about a part of a whole and about equal-sized pieces at once. Pictures, paper folding and fraction pizzas help before moving to numbers.
Can a nine-year-old solve a 3×3 cube?
Many can with the seven-step method and a few weeks of short practice. Start with the white cross, tick off each step, and use the virtual cube to rewind mistakes.
What maths should a 9-year-old be learning?
Four-digit numbers, long multiplication and division, equivalent fractions and decimals, angles, area and perimeter, bar charts. Every school sets its own order, so check the textbook your child uses.
Can a 9-year-old learn to code?
Python basics: print, variables, for loops and if statements, using short programs that can be changed.
Can a 9-year-old solve a Rubik's Cube?
The 3×3 seven-step method. Aim to solve it without help, then try timing a solve.
What school year is a 9-year-old in?
Roughly Grade 4 in the US, Year 5 in the UK and Class 4 in India. It depends on the country, the school and the birthday.
How much should a 9-year-old practise?
15 to 20 minutes a day is plenty, mixed across maths, coding and puzzles. Short and regular beats long and rare.
