Introduction Video Lecture | Abacus - Class 1

0:0:0: hello viewers welcome to pebbles ah
0:0:3: today we are going to learn new topic
0:0:6: that is abacus okay it's a simple
0:0:10: counting mission and counting device
0:0:14: and it's very useful for children by
0:0:17: simple learning counting numbers uh with
0:0:21: bright color beads okay i will show you
0:0:24: the abacus instrument and how to move
0:0:28: the beads and count the numbers okay let
0:0:31: me enjoy children and today uh we are
0:0:35: that is we are going to learn uh in a
0:0:38: joyful manner how to move the beads by
0:0:41: using abacus okay i will show you the
0:0:45: first i will show the instrument and ah
0:0:47: do you know the basic what is abacus and
0:0:51: the rod type okay first you have to
0:0:53: understand what is abacus i will show
0:0:56: the uh simple uh that is uh this is this
0:0:59: video is for preschool children from the
0:1:2: age level up to four
0:1:5: five and six okay four to seven age
0:1:9: level children or enjoy for this uh
0:1:13: using this device by using how to use
0:1:16: this device i will show you the device
0:1:19: okay
0:1:20: this is a
0:1:22: mathematical simple
0:1:24: abacus device okay and each row that is
0:1:29: it has 10 rods
0:1:32: okay how to move this to know that is 10
0:1:35: rods and by
0:1:38: counting numbers okay you have to start
0:1:41: from the
0:1:42: bottom to
0:1:44: up
0:1:45: okay this is a device ok for 10 rods
0:1:48: this is count by this 1 2 3
0:1:52: 4
0:1:53: five six seven eight nine and ten
0:1:57: this is a a backer skate and it has ten
0:2:0: rods and each rod has ten beads
0:2:5: okay this is a 10 beats abacus and this
0:2:9: is a 100 b abacus this is called 100 b's
0:2:13: because each row contains
0:2:16: 10
0:2:17: beats okay that is 10 draws okay
0:2:20: children and each row contains 10 beads
0:2:24: okay so 10 into 10 that is 100 so this
0:2:28: is called 100 beads abacus and which has
0:2:32: bright colored beads okay do you love
0:2:35: children because by simply you have to
0:2:38: sliding the beads from right to left and
0:2:42: you are
0:2:43: knowing two counting how to count the
0:2:45: numbers and place the numbers okay and
0:2:48: this is called the zero level
0:2:51: okay do you understand this this is a
0:2:53: zero level abacus that is no moment of
0:2:56: beats here
0:2:58: okay do you understand this ah for
0:3:0: reference because this is
0:3:3: one okay you are moving in the ones
0:3:6: place you move just like one number this
0:3:9: is called one okay and next one is a
0:3:12: tens place and hundredth place and it
0:3:15: grows above the up to ah next level
0:3:19: units okay first you have to
0:3:22: counting simple counting
0:3:24: by using this from the
0:3:27: ones place okay do you start okay from
0:3:29: this
0:3:30: basic rod okay okay i will show uh in
0:3:35: the board for how to move and do you
0:3:38: understand what is basic bead movement
0:3:42: of on abacus okay let me
0:3:45: see that is
0:3:48: what is abacus it is a simple
0:3:50: mathematical device okay
0:3:53: i'll show
0:3:55: for
0:3:56: single
0:3:57: that is only one's place
0:4:0: okay so
0:4:2: i have to draw two beats okay
0:4:5: one
0:4:6: and two
0:4:8: so how do you say the number
0:4:11: how do you say the number this is the
0:4:13: answer that is you say
0:4:15: 2
0:4:16: because once play is wrought it has two
0:4:20: beats
0:4:21: okay do you understand and next one
0:4:24: here
0:4:26: listen here this also once plays rod
0:4:29: okay this is one's place rod for o
0:4:32: o represent once
0:4:35: okay
0:4:38: listen here
0:4:40: one
0:4:41: two
0:4:42: three
0:4:44: four
0:4:45: and five
0:4:47: how do you say now
0:4:49: count the beats so one two three four
0:4:53: five
0:4:54: the answer is five
0:4:58: okay do you understand okay i will show
0:5:0: you next example
0:5:2: this is also a once place rod
0:5:5: okay
0:5:6: i have to draw beads listen here
0:5:12: four
0:5:14: five
0:5:15: six and seven
0:5:17: so simply you have to count the beats
0:5:19: and say the answer the answer is seven
0:5:23: okay one
0:5:25: two
0:5:26: three
0:5:27: four
0:5:28: five
0:5:29: six seven so answer is
0:5:32: seven
0:5:33: okay do you understand and next
0:5:36: one this also one's place rod
0:5:40: okay
0:5:42: listen here
0:5:44: one
0:5:45: two
0:5:46: three
0:5:47: and four
0:5:49: by counting this number you have to say
0:5:51: the answer what is the answer
0:5:54: 4 because 1
0:5:57: 2
0:5:57: 3 and 4 so answer is
0:6:1: 4
0:6:2: okay
0:6:3: and next
0:6:5: that is simple once place rod
0:6:9: okay
0:6:10: here i listen here there is no beads at
0:6:13: all here
0:6:15: okay i didn't write any bead i didn't
0:6:17: draw any bead what is the answer
0:6:21: there is no bead you have to say 0
0:6:27: okay this is answer 0 because there is
0:6:29: no beads on the rod
0:6:31: in ones place so simply by doing moving
0:6:36: abacus that is moving beats on abacus
0:6:39: you have to count the numbers
0:6:41: four two five seven and here is
0:6:45: zero
0:6:46: okay
0:6:47: next i have to show next up that is
0:6:51: next place that is one's place
0:6:54: okay we have discussed ones place
0:6:57: and simply doing
0:7:7: okay next we are going to learn that is
0:7:10: two place that is one's place and the
0:7:13: tens place okay listen here
0:7:18: i have to draw that is one's place
0:7:21: and tens place
0:7:23: okay
0:7:24: draw two rods
0:7:26: okay by simply drawing
0:7:30: here three beads and here
0:7:34: one bead
0:7:35: so what is the answer now
0:7:38: first count the beads in one's place
0:7:41: first you count the beads on first ones
0:7:44: place rod say the answer three
0:7:47: and the tens place rod it has only one
0:7:50: bead
0:7:52: okay children do you understand now this
0:7:54: is one's place and this is tens place
0:7:57: first you should write the
0:7:59: beads number of beads in one's place
0:8:2: only
0:8:3: okay so count the beads and write down
0:8:6: the answer is three and next we have to
0:8:8: count the beads on tens place that is
0:8:11: one
0:8:13: so answer is 13
0:8:17: do you understand okay
0:8:19: let me move on next example
0:8:22: simply that is one's place and tens
0:8:25: place it has two rods
0:8:28: okay i have to draw
0:8:34: okay
0:8:36: let me start to count first count the
0:8:39: ones place number
0:8:41: okay once play is wrong it has
0:8:44: one two so answer is two
0:8:48: and next you have to count the beats on
0:8:51: tens place so
0:8:53: 1 2 3
0:8:55: 4 and 5
0:8:57: you have to write the number
0:9:0: what do you say now this is
0:9:3: 52
0:9:5: okay so so this is a simple counting
0:9:9: method and let me know how to ah
0:9:13: form a pattern in a backers that is
0:9:15: counting by twos counting by fives and
0:9:19: counting by tens let me enjoy with
0:9:21: abacus okay
0:9:44: you
