Counting and Skip-Counting

Aligned to 2.NBT.A.2 — Common Core State Standards for Mathematics.

What this lesson teaches

Skip-counting means jumping by the same amount each time. You can jump by 5s, 10s, or 100s to count faster.

Example 1

Skip-count by 10s starting at 10: 10, 20, 30, 40, 50. Each number is 10 more than the one before.

Example 2

Skip-count by 5s: 5, 10, 15, 20, 25. This is also how you count nickels.

Example 3

Skip-count by 100s starting at 100: 100, 200, 300, 400. Only the hundreds digit changes each jump.

Contar salteado significa saltar la misma cantidad cada vez. Puedes saltar de 5 en 5, de 10 en 10 o de 100 en 100 para contar más rápido.

Ejemplo 1: Cuenta de 10 en 10 empezando en 10: 10, 20, 30, 40, 50. Cada número es 10 más que el anterior.

Ejemplo 2: Cuenta de 5 en 5: 5, 10, 15, 20, 25. Así también se cuentan las monedas de 5 centavos.

Ejemplo 3: Cuenta de 100 en 100 empezando en 100: 100, 200, 300, 400. Solo cambia el dígito de las centenas en cada salto.
