Understand the trick.
Use it yourself.

  1. 01

    Meet a problem

    Start with a useful piece of mental maths, not a speed test.

  2. 02

    Choose a strategy

    Spot Make 10, compensation, halve and double, or another shortcut.

  3. 03

    See why it works

    A worked visual proof makes the idea concrete and memorable.

  4. 04

    Prove you understand

    Apply the strategy to a fresh problem and add it to your collection.

What children explore

A whole map of useful maths.

+

Add & subtract

Make 10, compensation, near doubles, bridging, and place-value thinking.

×

Multiply & divide

Times-table patterns, doubling, halving, remainders, and divisibility rules.

½

Fractions & decimals

Visual relationships that connect parts, decimal values, and percentages.

□

Measure & patterns

Area, perimeter, number patterns, and harder topics when a grown-up decides.

Made for families

Progress stays useful—and private.

The local grown-up dashboard shows which strategies a child has genuinely secured. Three difficulty levels and direct topic revision make it easy to match practice to the learner.

Nothing leaves the device.

No analytics, advertising, account profile, or cloud progress record. AddVenture works fully offline after installation.
