The ability to multiply with your fingers is a valuable skill, and mankind has known how to count multiplication tables on your fingers since at least the 15th century. We may have mobile calculators, but in many cases, it's actually easier to keep your phone in your pocket and multiply on your fingers. This technique can also be helpful for toddlers who have trouble learning endless math formulas.
You can start learning the multiplication table on the fingers after the child knows the multiplication from one to five. Already on the basis of this knowledge, you can develop a skill in the literal sense of manual multiplication. So let's get started?
Multiplication table on fingers: nine
Keep your hands in front of you, palms up. Each of your ten fingers represents a number. Moving from the thumb of the left hand to the thumb of the right hand, count the numbers from one to ten.
Point the finger whose numbercorresponds to the number you want to multiply by nine, down to your body. So, for example, if you want to decide how much 9x3 will be, you will need to hold the middle finger with your left hand. The middle finger represents the number three, because if you count your fingers from one to ten, starting with your left thumb, your middle finger is the third one.
Counting
The problem is solved by counting fingers to the left and to the right. First count the fingers to the left of your bent finger - in this case there will be two. Then count the fingers to the right of your bent finger - in this case it should be seven. The first digit of the answer is two, and the second digit is seven. The answer is 27!
This is how the multiplication table for 9 works on the fingers. Try it with other multiples of nine. How would you multiply 9 by 2? How about 9 by 7? This method is incredibly simple and understandable even for kids. As practice shows, children are more willing and successful in studying mathematics, knowing this interesting way to calculate the product of two numbers!
Multiplication table on fingers for six, seven, eight and ten
Hold your hands so that your palms are facing your body and your fingers are facing each other. Again each finger will represent a number. Your little finger represents the number six. The ring finger will have a value of seven, the middle one - eight. The index fingers of your hands will symbolize the nine, and the thumbs - the ten. So, how to learn the multiplication table on your fingers?
Calculation scheme
In order to calculate the product of two numbers, you need to touch two fingers, the numbers of which correspond to the numbers you need to multiply.
For example, if you want to calculate what 76 will be, you need to touch the ring finger of your left hand (since it represents the number on the left) with the little finger of your right hand, since it means the number on the right. Again, remember that each finger represents a number, in which case your ring finger represents seven and your little finger represents six. So you need to connect them to solve this math problem.
You may have to bend your wrist in weird ways to calculate the product of two numbers! Who said it would be easy?
To make sure you understand the finger multiplication table technique for six, seven, eight and ten, check yourself. If you need to calculate what the product of 9 and 7 will be, then which fingers would you connect? Think! The answer will be in the next sentence.
So, consider that you have learned the multiplication table on fingers for six, seven, eight and ten, if as an answer, which fingers you need to connect to calculate what the product of 9 and 7 is, you chose the index finger your left hand and the ring finger of your right hand. The case is small!
How to count?
The next step is to simply count the fingers that are touching, as well as the fingers underneath. They will represent decimal numbers. ATIn this case, you will count the ring finger on the left hand, the little finger on the left hand, and the little finger on the right hand. Each finger you count will equal 10. In this case, the total is 30.
Multiply the remaining fingers. The next step is to add up the number of fingers on each hand, not counting the fingers that touch each other. First count the number of fingers on the left hand that are above the touching fingers - in this case there will be 3. Then count the number of fingers of the right hand above the touching fingers - in this case there will be 4. 34 \u003d 12. Add the two numbers together, to find your answer. In this case, you need to add 30 to 12. The total will be 42. If 7 is multiplied by 6, then the answer will be the same and will be equal to 42!
The multiplication table on the fingers may seem complicated at first, but if you carefully understand it, it is much easier to learn than the endless formulas in a real math table.
Multiply by 10 using the same method. For example, if you want to find the answer, which is 10 times 7, then start by touching the thumb of your left hand to the ring finger of your right hand. Count the number of fingers under the connecting fingers, including the fingers that touch each other. You should have a total of 7, which means 70. Then count the number of fingers above the touching fingers of the right and left hands. There should be 0 on your left and 3 on your right. Now multiply 3 by 0=0 andadd 70 to 0 for the answer. Answer 10 times 7=70!
Result
Try it with other multiples of six, seven, eight and ten. How would you multiply 8 and 8 with your fingers? What about 8 and 10? If you are interested in the question of how to teach the multiplication table on the fingers of your child, then just try to include the practice of counting the product of various numbers in your daily routine. You will not even notice how the baby will begin not only to quickly count the product of two numbers, but also eventually remember the multiplication table.
This is the whole attraction of this method - it is fun, makes you think logically, turn on mathematical abilities and at the same time develops memory. What could be better for a child? Let's finally calculate what the product of 6 and 10 will be? What about 8 and 9? What about 7 and 8? Here is such an entertaining math.
