Finger Method ASL1W1C1

FINGER TECHNIQUE

Today students will learn finger technique. In finger technique we can show 0-99 by using our two hands.

It’s like a magic. Only ALOHA’s student can count 0-99 by using two hands.

IDENTIFYING LEFT AND RIGHT HAND                                                     

Now students will learn which one is their left hand and which one is right hand. Tell your child to open thumb and index finger. How in which hand they can show perfect L that hand will be left hand and the other hand will be right hand.

INTRODUCE FINGER’S NAME

Index Finger, Middle Finger, Ring Finger, Little Finger, and Thumb Finger.

Now take the note book, put your child’s left hand on the note book and tell your child to draw hand on the note book. And if possible, s/he can color the fingers one by one.

Thumb = Red, Index = Green, Middle = Yellow, Ring = Blue, Little = Orange   

LET’S LEARN HOW TO COUNT

  • Right hand is for unit digits / ones (0, 1, 2, 3,4, 5, 6, 7, 8, 9) 
  • Left hand is for Tens Digit. (10, 20, 30, 40, 50, 60, 70, 80, 90)

HOW TO COUNT IN RIGHT HAND

Now students will learn how to count with their 10 fingers. So, let’s start with “0”. To show 0, hold the thumb of you right hand with your four fingers. This will be 0 and its look like the number 0.

Open your right hand’s index finger, this is 1.

Then open/ add the middle finger with index finger, this will be 2.

Now open/ add the ring finger with index & middle finger, this will be 3.

Then open/add the little finger with index, middle & ring finger, this will be 4.

So, you can understand that the value of each finger of right hand is 1 except thumb.

Now close all the 4 fingers and open only thumb. This is 5. So, the value of thumb is 5.

In this way, if you open 1 finger with thumb it is 6, if you open 2 fingers with thumb it is 7, if you open 3 fingers with thumb it is 8, and if you open 4 fingers with your thumb finger it will be 9.

In this way if you open all the fingers of right hand this will be 9.

HOW TO COUNT IN LEFT HAND

To show 10 you have to show left hand’s index finger.

After 10, to show 11 we take the left-hand index, it carries 10 and the right-hand index finger, it carries 1 (10 + 1 = 11). That means you need to open left hand’s index finger and right hand’s index finger as well.

Now to show 12 to 19 left hand’s index finger will remain open and then count 2 to 9 in right hand as shown above.

To show 20, open left hand’s index & middle finger and right hand will be 0.

21 to 29 – To show 21 need to open left hand’s index & middle finger and right hand’s index finger as well. Now to show 22 to 29 left hand’s index & middle finger will remain open and then count 2 to 9 in right hand as shown above.

In this way the value of each finger of left hand will 10 except thumb and the value of left hand’s thumb will be 50.

So, if you open all the fingers of left hand this will be 90 and all the fingers of right hand will be 9. Altogether this will be 99.

HOW TO DO ADDITION & SUBTRACTION BY USING FINGERS

To do addition & subtraction you have to follow some rules.

  1. When we will add we will add from our index finger to little finger
  2. When we will subtract, we will do from our little finger to index finger.
  3. If the digit we will add or subtract is bigger than 5, suppose 6, 7, 8 etc. in that case we will add or subtract 5 first.

We will learn addition first. Here in the below there are some examples of addition. Let’s practice these sums by using our fingers:

Addition

Example:  1+1, 1+2, 1+3, 1+5, 1+6, 1+7, 1+8                                      

                 10+10, 10+20, 10+30, 10+50, 10+60, 10+70

                 10+1+5, 12+1+10       

Look at the first sum 1 + 1

First you need to show 1 open right hand’s index finger and  then to add 1 need to open right hand’s middle finger. Answer is 2.

1 + 3

First you need to show 1 open right hand’s index finger and then to add 3 need to open right hand’s middle, ring and little finger. Answer is 4.

1+8

First you need to show 1 open right hand’s index finger and then to add 8 need to open right hand’s thumb then middle, ring and little finger. Answer is 9

10+50

To show 10 open left hand’s index finger and then to add 50 need to open left hand’s thumb.

Answer is 60

12+1+10       

Now it’s time for bigger sum

Step 1 to show 12 open left hand’s index finger and right hand’s index and middle finger.

Step 2 To add 1 open / add right hand’s ring finger. Now you have 13

Step 3 To add 10 open / add left hand’s middle finger.

The answer is 23.

Subtraction

Example: 4 – 1, 4 – 2, 4 – 3, 4 – 4, 9 – 5, 9 – 6, 9 – 7, 9 – 8, 9 – 9

               40-10, 40 – 20, 40 – 30, 40 – 40, 90-50, 90 – 60, 90 – 70, 90 – 80

               14 – 2 + 5 – 1, 43 + 50 – 90, 22 – 11 – 1 + 6

4 – 1

Step 1 Show 4 by opening right hand’s index, middle, ring and little finger.

Step 2 To subtract 1 close right hand’s little finger.  Answer is 3.

9 – 7

Step 1 To show 9 open all the fingers of right hand

Step 2 To subtract 7 close thumb (5) first then close little and ring finger.

Answer is 2.

40 – 30

Step 1 Show 40 by opening left hand’s index, middle, ring and little finger.

Step 2 To subtract 30 close left hand’s little finger then ring finger and lastly middle finger.

Answer is 10.

22 – 11 – 1 + 6

Step 1 to show 22 open left hand’s index & middle finger and right hand’s index and middle finger.

Step 2 To subtract 11 close left hand’s middle finger first then right hand’s middle finger. So, you have now 11 in your hand.

Step 3 To subtract 1 close right hand’s index finger. You have now 10 in your hand.

Step 4 Now to add 6 open right hand’s thumb (5) and index finger.

Answer is 16.

CLASS WORK 1A

Now you are ready to do sums from your book.

1.2 try to finish this portion within 15 min. Page 2.

ORAL CALCULATION

Parent will tell the sums from fingering part and student need to do and write the answers maintaining numbering sequences. Listening to sums called out and doing the same to give answers not only enhances the listing skill but also the hearing sense establish better memory skills. Ability to do fast and accurate mental arithmetic calculation.  Students will write answers one by one in Exercises 1 and 2.
