Fixed-value symbol model for 100
one unit in the hundreds place
One square-shaped fixed-value symbol worth 100 represents the entire number; the tens and ones places contain zero units.
This additive decimal model decomposes the number into repeated fixed-value symbols. Each symbol keeps its value wherever it appears, and repetitions add, so the complete pattern composes 100.

Why it stands out
Patterns inside 100
One hundred introduces the square-shaped hundreds unit while connecting fixed-value symbol composition to a 10-by-10 array and the base-ten power sequence.
Ten rows of ten make 100
Because 100 = 10 × 10, one hundred objects can form a square with ten objects in every row and column.
Its prime factorization is 2² × 5²
That factorization gives 100 nine positive divisors: 1, 2, 4, 5, 10, 20, 25, 50, and 100.
One symbol worth 100 replaces ten symbols worth 10
A single hundred has the same value as ten tens or one hundred ones, demonstrating regrouping between decimal places.
