Which Is Bigger?

Aligned to 1.NBT.B.3 — Common Core State Standards for Mathematics.

What this lesson teaches

To compare two numbers, first look at the tens. The number with more tens is bigger. We use > for greater, < for less, and = for equal.

Worked example

Compare 34 and 28. 34 has 3 tens, 28 has 2 tens. 3 tens is more, so 34 > 28.

Practice questions

  1. Compare 45 and 52 with >, <, or =.
  2. Compare 61 and 61 with >, <, or =.
  3. Compare 27 and 19 with >, <, or =.

¿Cuál es más grande?

Para comparar dos números, primero mira las decenas. El número con más decenas es más grande. Usamos > para mayor, < para menor y = para igual.

Ejemplo: Compara 34 y 28. 34 tiene 3 decenas, 28 tiene 2 decenas. 3 decenas es más, así que 34 > 28.
