Tile Trickery Town
Square tiles and silly lies. Who can trust the Goblin?

Momo: Square tiles for a new playground! Momo counted, just to be sure.
The Sum Goblin: Take my tiles, Momo. Lie about side length.
Momo: Side length? Whatโs that? Maybe I should measure... or ask?
Squares and square roots
Squares numbers times themselves
Square roots undo squaring
Four's square root is two
Momo: I see, so 2 times 2 is 4. And 4 is the square of 2!
The Sum Goblin: Say tile 4 is 2 squared. Momo says 3, buys more!
Momo: If a tile is 9, whatโs its square root? 3 times 3 is 9!
3 squared = 9
Square root of 9 = 3
Momo's tip
Square root of 16 is 4
4 squared = 16
Square root of 16 = 4
Momo: Always check by squaring. If youโre right, you get the tile!
Your turn, hero!

A square tile covers 81 small squares. What is the square root of 81?
9. 9 ร 9 = 81.
The Sum Goblin: Oh, and Momo, if 9 tiles are 3 squared, why not 10? Haha, another tile for free!
What is the square root of 49?
7. 7 ร 7 = 49.
The final battle

Momo finds 225. Square root, then square. What number?
225. 15 ร 15 = 225.
The Sum Goblin: Square roots? Boring. Momo will fall.
Momo: No, no! I measured and counted. Squares never lie!
Squareville playground is safe. The goblinโs tricks are up!
