hello little angles. I am so happy to see you
in the last lesson we 've learned
to do addition using the number line. Do
you know that we can also use the number line
To do subtraction I will show you how
to do it right in this lesson
Are you ready? let's begin
how to do subtraction using the number line
for example how to find 6-3 using the number line
let me show you. To find six minus three we start from number six
then jump three
numbers to the left then see the number
where we stop to find the difference.
Here we stop at number three
therefore six minus three equals three.
It 's easy right
Now, Let 's take another example. Let 's find 8-5
using the number line
we start from number eight then jump five numbers to the left
then see the number where we
stop to find the difference. Here we
stop at number three
therefore eight minus five equals three
it's simple isn't it.
now let's have some practice
Task 1: find the difference using the number line
3 minus 1, 7 minus 4, 8 minus
3, 10 minus 6
to do this task download the worksheet
below and print a copy then try to do it
on your own. Pause this video while you
are doing it when you finish replay the video
and check the answers with me
now let's find the answers together
first, to find 3 - 1. We start from
number three then Jump one number to
the left. Then see the number where we
stop to find the difference
Here we stop at number two.
Therefore three minus one equals two
Next, to find seven minus four. We start
from number seven then jump four
numbers to the left. Then see the number
where we stop to find the difference
Here we stop at number three.
Therefore 7 minus 4 equals 3
next, to find eight minus three. We start from number eight then jump three numbers to
the left. Then see the number where we
stop to find the difference.
Here we stop at number five.
Therefore eight minus three equals five
the last one, to find ten minus six. We
start from number ten. Then jump six
numbers to the left. Then see the number
where we stop to find the difference.
Here we stop at number four. Therefore
ten minus six equals four.
I hope you enjoy the lesson. Bye for now and see you soon!
