Are you a beginner to learn the concept of Skip Counting by 3S? If yes, then check out here to know each and every detail about this concept. Skip counting is considered a skill and also viewed as an arbitrary math skill. With the help of skip counting facts and definitions, you can improve learning the multiplication facts and along with the number sense. Skip counting deals with counting the numbers by 2S, 3S, 5S, etc Here in the below sections, we will see a detailed explanation on Skip Counting by 3S. Follow the facts, definitions, examples, etc.
Skip Counting by 3S – Introduction
Before, going to know how to skip count, first, we will learn about what is skip counting. Skip Counting is a technique or method of counting numbers other than 1. In the method of skip counting, we add the same numbers to the previous number each time.
Example:
Find the series of numbers with the skip count by 2?
Solution:
After applying the skip count by 2
we get the number series as 2,4,6,8,10,12…
Therefore, we get a series of even numbers.
Important Points of Skip Counting
- Skip Counting on any number is possible.
- This helps the numbers to count easily.
- The skip counting method involves a huge application in the multiplication of tables.
- Skip counting can be done with any numbers like 2S, 3S, 5S, 10S, 100S, etc.
Skip Counting by 3S – Important Points
- To skip count by number 3, keep adding the value 3 to get the next number.
- We can notice the diagonal patterns in the number grid when applying the skip counting by 3.
- Use the grid for the skip count and we miss out on two numbers and write the third digit.
- Skip counting by 3S from zero is essential in learning the 3’s timetable.
- For skip counting by 3S, we get the number line as 3,6,9,15,18,21,24,27,30 etc
- Learning the counting by 3 patterns till to 30 will help you with counting in 3’s with the larger numbers.
How to Skip Counting by 3?
Skip counting is the fastest way to count than simply counting one by one.
Skip counting by 3S means, adding the three numbers to get the next number, which means that we skip two numbers out in the process.
The number series of skip counting by 3S from zero, we have:
0,3,6,9,12,15,18,21,24,27,30
Since the pattern is not clear, the number grid will help you to understand the counting by three easily. With the help of the number grid, we can easily see the numbers that come next, and also we can see the numbers we skip while forming the number series.
To notice the pattern in the 3’s timetable, we have to look at the units digit column for the numbers.
Consider 30, we check for the units digit of 30 i.e., 0
Therefore, 0+3=3, hence, 30 + 3 = 33
Continuing to add three numbers, we get
30,33,36,39,42,45,48,51,54,57,60
Forward Skip Counting
In the forward skip counting, we count the numbers in the forward direction. It means that we skip the count of numbers for positive values. Counting the numbers with skip values has major applications in the real life. For suppose, if we want to count 100 marbles, use the skip counting method. If we count one-one marble, it consumes a lot of time. Thus, we use the skip count method, by any of the big numbers like 10 or 20, then we will count them quickly.
Backward Skip Counting
Backward skip counting is also essential for the students which implies counting to the negative numbers. For example, if we want to count by -2 then the number series is
-2,-4,-6,-8,-10 etc.
Strategies to Skip Counting
1. Questioning
A much-overlooked strategy of teaching is questioning. There are various questions that can give you clarity on the topic. To skip count by 2S, try asking the question like “In how many ways you can count to 24?” or you can also ask to “Can you count to 40 by 10’s? Why or Whynot?”
2. Use a Calculator
Generally, we don’t use calculators when solving skip counting problems. However, it can be a useful and fun tool when solving this skill. First of all, practice how to change the numbers by pressing the equal sign. This kind of strategy helps to build the number fluency and also to remember the skip counting values.
3. Play Game
This kind of strategy is used for kids. This is an easy process where kids can remember skip counting and also can have fun. Make the students stand or sit in a circle. Stand counting the student with a random number and then they continue to count by skipping the number until they go the complete way around the circle.
4. Use Manipulatives
To remember the method and rules easily, make use of manipulatives like paper clips, candy, snap cubes. With the help of these manipulatives, you can recite a string of numbers and can understand the purpose of skip counting.
Skip Counting by 2S
In this method, we add the number 2 for each counting. In this manner, we get alternate numbers. For example, if we start counting from 2, then by skipping the count of numbers, we get the number series as
2,4,6,8,10,12,14,16,18,20,22…
Skip Counting by 4
When we skip count by 4, then we have to add 4 in each step. The procedure we follow for skip count 4 is
0+4 = 4, 4+4 = 8, 8+4 = 12, 12+4=16, 16+4 = 20, 20+4 = 24,24+4 = 28 etc.
Skip Counting by 5
In this method, we add the number 5 for each counting. In this manner, we get numbers with a difference of 5. For example, if we start counting from 5, then by skipping the count of numbers, we get the number series as
5,10,15,20,25,30,35,40,45,50,55,60,65,70…
Skip Counting by 10
When we skip count by 10, then we have to add 10 in each step. The procedure we follow for skip count 10 is
0+10=10, 10+10=20, 20+10=30, 30+10=40, 40+10=50, 50+10=60…
Skip Counting by 25
In this method, we add the number 25 for each counting. In this manner, we get numbers with a difference of 25. For example, if we start counting from 25, then by skipping the count of numbers, we get the number series as
25,50,75,100,125,150,175,200,225… etc
Skip Counting by 100
In this method, we add the number 100 for each counting. In this manner, we get numbers with a difference of 100. For example, if we start counting from 100, then by skipping the count of numbers, we get the number series as
100,200,300,400,500,600,700… etc
