Skip counting to 1,000

What is this skill?

Skip counting to 1,000 means counting forward in equal jumps of 5, 10 or 100, often starting from a number that is not zero. Second graders might count by 10s from 230 (230, 240, 250, 260) or by 100s from 340 (340, 440, 540, 640). In first grade they skip counted from zero; now the starting points and the numbers are bigger.

The key is noticing which digit changes. Counting by 10s, the tens digit goes up by one each time and the ones digit stays the same. Counting by 100s, only the hundreds digit changes. Counting by 5s, the ones digit alternates between two values, such as 5 and 0 or 0 and 5.

Why it matters

Skip counting by 10s and 100s from any number is a mental math tool second graders use constantly. To add 340 + 200, a child can count 440, 540. To find 230 + 40, they can count 240, 250, 260, 270. It makes three-digit addition and subtraction much less dependent on paper.

It also shows place value in motion. Watching 290 become 300 when counting by 10s shows that ten tens make a hundred. Counting by 5s connects to telling time on a clock and to counting nickels, and all of it prepares for multiplication in third grade.

Common mistakes

• Getting stuck at a hundred. Counting by 10s from 270, children often say 280, 290, 2100 or 200. Pausing at 290 and asking "What is ten more than 29 tens?" helps them see that it is 300.
• Changing the wrong digit, such as counting by 100s from 340 and saying 350, 360. Ask your child which place should go up before they start.
• Counting by 5s from a number that does not end in 0 or 5, such as starting at 15 but sliding back into the familiar 10, 15, 20 path after a few jumps. Writing the first few numbers down keeps the pattern visible.
• Losing the step size partway through a long sequence. Tapping a finger or clapping for each jump helps children stay in rhythm.

How to help at home

• Count by 10s and 100s on car rides or walks, starting from any number your child chooses. Switch step sizes at a signal for an extra challenge.
• Use a hundred chart to show counting by 10s as moving straight down a column. Then talk about what happens after 100.
• Count nickels by 5s, dimes by 10s, and dollar bills by 100 cents. Mixing coins later builds on this.
• Play "Fill the gap": say three numbers in a pattern, like 450, 550, 650, and ask for the next two. Then ask your child to make a pattern for you.
