we studied division before so today we
will revise division but using the
number line okay so today we will revise
division using the number line and we
will find out what is the remainder of
division what is the remainder of a
division okay so let's see let's start
by this example I have a twelve happy
faces here and I want to share these
happy faces equally between these three
baskets so if I want to share these
happy faces equally when I put a happy
face on a basket I should put in one in
the other baskets okay so let's complete
one here and one here and one here okay
so we are making groups one here one
here and one here okay but there are
some more here one here
and one here and one here okay now there
is no more there is no more happy faces
left here okay but how many happy face
are there in every group in every basket
how many happy faces are there there are
four four four so when I share twelve
happy faces equally between three groups
every group will have four happy faces
every group will have four happy faces
so the answer is four so I can say the
question in other words how many threes
are there any twelve again 12 divided by
3 means how many threes are there in
twelve the answer is 4 so I can say
there are four threes in 12 there are
four threes and twelve okay but
every time I don't have to make happy
faces and it will be a hard process so I
I should make the number line but how
can I use how can I use the number line
to find the answer of a division ok what
is the divisor here it is what 3 so I
will make jumps of three I will start at
zero and I will make jumps of 3 so 0
plus 3 equals 3 can I make 3 more yes I
can make another 3 so 3 plus 3 equals 6
can I make more threes yes 
6 plus three equals nine can I make more
threes yeah I still have. 9 plus 3 equals
12 so I landed on 12 so I should stop
now
because I landed on 12 okay now I want
to see how many threes are there how can
I find it out by: Counting the jumps
so I counted one two three four so I
make four jumps to land on 12 I made
four jumps of three to land on twelve so
the answer is 12 so it is easy to find
the answer of a division using the
number line by making jumps by making
jumps another example and this is your
turn there are 20 stars I want to divide
them equally into five groups so tweeny
divided by 5 equals 3 or 4 or 5 the answer
is number 2 let's check the answer I will
start where "arwa"   from zero
okay and I will make jumps of what :five
okay so zero plus five equals what five
okay can I make more jumps yes plus five
equals ten can I make more jumps yes
plus five equals  15 can I make more
jumps yes
plus  five equals  20
so I landed on 20 so I should
stop now because I landed on 20 so how
many jumps did I make let's count one
two three four so I need four jumps of
five to land on twinning so the answer
is four so 50 divided by 10 equals what
five four six and the question in other
words how many tens are there in 50
i want to see how many things are there in
50 okay so I will use the number line I
will start at zero and I will make jumps
of what jumps of 10  so every jump is
ten steps so zero plus 10 equals 10 can
I make more tails yes 10 plus 10 equals
20
okay 20 plus 10 equals 30
okay can I make more tens yes plus 10
equals 40 plus 10 equals 50 so I landed
on 50 so I should stop now because I
landed on 50 okay and what is the answer
of the question let's count how many
jumps did I make to land on 50 so I made
one two three four five so I counted
five jumps of ten to land on 50 so the
answer is
five . so I should start where we start
at zero and I will make jumps of what I
will make jumps of three so 0 plus 3
equals 3 .  plus 3 equals 6. plus 3 equals 9
plus 3 equals the 12 plus 3 equals 15
plus 3 equals 18 plus is 3 equals 21
plus 3 equals 24 plus 3 equals 27 and I
should stop here because I landed on 27
let's count how many steps how many
jumps of 3 did I make I make 1 2 3 4 5 6
7 8 9 so I made 9 jumps of 3 to land on
27 so 27 divided by 3 equals 9
okay
