Roots
Enter the Root Grid. Learn what a square root means, recognise perfect squares, estimate roots, simplify radicals, and solve real problems without treating mathematics like a bag of magic spells.
Build a square. Discover its root.
A square root asks: “What side length would create this area?” Try it physically.
√16 = 4 because 4² = 16.
Decode the pattern.
Tap a module. Each one gives you a different mental tool for square roots.
Perfect Squares
Numbers made by multiplying an integer by itself.
Estimate the Root
Trap a non-perfect square between two perfect squares.
Number Line
See where a square root lives between whole numbers.
Simplify square roots.
Pair identical prime factors. Every complete pair can leave the radical.
When the root is not obvious.
For larger perfect squares, the long-division method gives a systematic route.
Flashcards: quick scan.
Small cards are for retrieval practice. Tap to flip. Don’t peek too early.

Use this mode when you want to stop, think, and explain the idea in your own words.
Calculate. Explain. Verify.
Choose a mission type, solve it, then verify your answer by squaring it.
Real-world root missions.
Square roots become useful when the unknown is a length, side, distance, or dimension.
Teach it like a briefing.
Use this mode for a lesson, revision, or a quick classroom explanation. Arrow keys work too.
Three attempts. Then reveal.
Practice should expose the mistake, not punish it. Each question allows three attempts.
