Exponents for Kids: What "Squared" Means
"5 squared" is not about a geometric shape — it is about multiplying a number by itself. Here is the idea through real squares and cubes.
Squaring a number — multiply it by itself
5 squared (5²) means 5×5=25. The name "squared" comes from geometry: the area of a square with side 5 equals 5×5.
💡 Anchor: draw a 5×5 grid of squares and count the squares — you get 25, the same as 5².
Cubing a number
5 cubed (5³) means 5×5×5=125. Like the volume of a cube with side 5 — use LEGO bricks to visualize it.
