Starts where your child is, not where their age says

Five questions to begin

Tivumo asks five short questions and opens every class up to the hardest one your child answers correctly.

Gaps from earlier years

Class 8 — numbers, algebra, percentages — is always there for revision, without any sense of going backwards.

Room to run ahead

A child who is ready can move into Class 10. Mastery unlocks the next maths, not points.

How to help a 14 year old with maths at home

Measure something tall

Use a shadow and a stick to work out the height of a building: similar triangles and trigonometry in one walk.

Graph something they care about

Screen time or savings over a month, plotted by hand, makes a straight line and its slope real.

Ask for the picture first

Before solving, ask what the graph or figure would look like. Board questions reward that habit.

Space the revision

Twenty minutes on a chapter today, again in three days, again next week, beats three hours the night before.

Treat mistakes as information

Look at which step went wrong rather than just the final answer. Most marks are lost in one repeated step.
