Skip counting is a fun way to count faster! Instead of counting one by one, we can count in groups. This helps us count big numbers quickly. For example, if you have a lot of marbles, you can group them in sets of five and count by fives.
Imagine you have a bucket with 25 marbles. There are 5 red, 5 blue, 5 green, 5 yellow, and 5 purple marbles. Instead of counting each marble one by one, you can count by fives. Let’s count together: 5, 10, 15, 20, 25. See how fast that was?
A 100 chart is a great tool to help us see patterns when we skip count. Let’s start with skip counting by tens. When we count by tens, we say every tenth number. The numbers look like this: 10, 20, 30, 40, 50, 60, and so on.
Let’s practice counting by tens. I’ll start, and you can join in: 10, 20, 30, 40, 50, 60. Great job! When we count by tens, we skip 10 numbers each time. Try counting on your fingers from 11 to 20. You should have 10 fingers up!
Now, let’s try skip counting by fives using a 100 chart. We count every fifth number. The numbers look like this: 5, 10, 15, 20, 25, 30, 35, 40, 45.
Let’s count together: 5, 10, 15, 20, 25, 30, 35, 40, 45. Awesome! When we count by fives, we skip 5 numbers each time. Try counting on your fingers from 6 to 10. You should have 5 fingers up!
Let’s learn how to skip count by twos. We count every other number. The numbers look like this: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20.
Let’s count together: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. Great job! When we count by twos, we skip one number each time. This helps us see patterns of odd and even numbers.
Even numbers can be split into two equal groups. They end in 0, 2, 4, 6, or 8. For example, 8 is even because it can be divided into two equal groups. Odd numbers cannot be split into two equal groups. They end in 1, 3, 5, 7, or 9. For example, 7 is odd because there is one left over when you try to split it into two groups.
Now you know how to skip count by twos, fives, and tens! Keep practicing, and you’ll get even better at it!
Marble Grouping Game: Gather a collection of small objects like marbles, buttons, or coins. Ask a grown-up to help you count them by grouping them into sets of 2, 5, or 10. How many groups can you make? Try counting each group using skip counting. For example, if you have 20 marbles, you can group them into sets of 5 and count: 5, 10, 15, 20. Can you find a different way to group them?
Skip Counting Walk: Go for a walk with a family member or friend. As you walk, practice skip counting by twos, fives, or tens. For example, count the number of steps you take by twos: 2, 4, 6, 8, 10. How far can you count? Try to notice patterns in the numbers as you walk. Do you see any even or odd numbers?
Pattern Hunt: Use a 100 chart to find and color patterns when skip counting by twos, fives, and tens. Notice how the numbers line up. What do you see? Can you find any other patterns? Try skip counting backward from 100 by tens. What numbers do you land on?

Skip counting and odd and even numbers. We use skip counting to help us count large groups of objects more quickly. For example, if we needed to count a bucket full of marbles, we can group them in sets of five. Instead of counting them one by one, we skip count the groups by five.
If there are 25 marbles in the bucket—5 red, 5 blue, 5 green, 5 yellow, and 5 purple—we can figure out the total by counting by fives. Let’s count together: 5, 10, 15, 20, 25 marbles in total.
A 100 chart can show visual and number patterns to help with skip counting. This is a 100 chart for skip counting by tens. Every tenth number is counted, and the ones place in this chart is always zero, while the tens place increases by one.
Let’s try counting by tens. Here is a list of numbers with two missing. I will start counting, and you can count along with me: 10, 20. We’ve hit a blank. What number do you think goes in this blank? That’s right, 30! Let’s continue counting: 40, 50. Here is another blank. What number do you think goes in this blank? That’s right, 60!
Now let’s count the whole list together: 10, 20, 30, 40, 50, 60. When we count by tens, we skip 10 from the previous number. For example, there are 10 numbers between 10 and 20. Count along with your fingers as I start at 11 and count to 20: 11, 12, 13, 14, 15, 16, 17, 18, 19, 20. You should have 10 fingers up right now.
We do this to show that there are 10 numbers between 10 and 20, between 20 and 30, between 30 and 40, and so on. Once you know this, you can count by tens.
Now, let’s look at a 100 chart for skip counting by fives. Every fifth number is counted, and the ones place in this chart shows a pattern of 5 and 0. Let’s try counting by fives. I will give you a list of numbers, and I will skip count by 5. There will be some numbers missing, and you can help me find them.
Okay, let’s begin: 5, 10. We’ve hit a blank. What number do you think goes in this blank? That’s right, 15! Let’s continue: 20, 25, 30. We’ve hit another blank. What number do you think goes in this blank? That’s right, 35! Now let’s keep going: 40, 45.
Great! Now we can count the whole list together: 5, 10, 15, 20, 25, 30, 35, 40, 45. Great job! When we count by fives, we skip 5 from the previous number. There are five numbers between 5 and 10. Count along with your fingers as I start from 6 and count to 10 to show you which numbers we skipped when we count by 5. Are you ready? Okay, let’s go: 6, 7, 8, 9, 10. You should have 5 fingers up.
This shows you that there are 5 numbers between 5 and 10. Now you know how to skip count by fives.
Let’s look at another 100 chart that will help us skip count by twos. We will skip count every other number. Notice the visual pattern of every other number being counted. The ones place repeats: 2, 4, 6, 8, and 0.
Let’s try counting by twos. Here is another list, and I will count while you help me fill it in. Ready? Okay, let’s begin: 2, 4, 6. Here’s a blank. What do you think goes in the blank? That’s right, 8! Let’s continue: 10, 12. Here’s another blank. What do you think goes in this blank? That’s right, 14!
Let’s keep going: 16, 18, 20. Great! Now let’s count all the way through from the beginning. Count with me: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. Great job!
When we count by twos, we count up from the previous number. So we count to skip three, count four, and skip five, count six, and skip seven, and so forth.
Can you keep counting by twos? Counting by twos can show a pattern of odd and even numbers. Even numbers can be broken into two equal groups. When we start with two and count by twos, we are using even numbers. Even numbers will always have a 0, 2, 4, 6, or 8 in the ones place.
Is 8 an even number? Yes, 8 is an even number because it can be broken into two equal groups. Odd numbers cannot be broken into two equal groups; there will always be one leftover. When counting by twos and starting with one, you will be using odd numbers. Odd numbers always have a 1, 3, 5, 7, or 9 in the ones place.
Is 7 an odd number? Yes, 7 is an odd number because it cannot be broken into two equal groups; there would be one left over.
