The Subtraction Symbol
In this video, we will learn how to read,
write, and model subtraction sentences with numbers up to 10 and represent subtraction using
the minus sign. This is the subtraction symbol. We use it to say subtract, take away, or
Here are three ladybugs munching on a
leaf. If one of the ladybugs flies away, there
will be two left. We could use counters to help us model
this subtraction problem. We can use three counters because there
are three ladybugs to begin with. We need to take one of the counters away
because one of the ladybugs flew away. And there are two counters left. Three take away one is two. Let’s practice subtracting.
What is four subtract one?
We’re shown a picture of four light
bulbs. One of the light bulbs is not
working. So, we have to take it away. We need to work out what four take away
one is. Let’s use counters to help us model
this subtraction problem. Here we have four counters to represent
the four light bulbs. And we need to take one away. How many counters are left? There are three left. Four take away one is three.
Find the answer to eight subtract
We’re shown a picture of eight pieces
of candy. And we have to take away three. We could use eight bricks to represent
our eight pieces of candy. If we take away three of our bricks,
how many do we have left? Let’s count them. One, two, three, four, five. Eight take away three is five. The answer is five.
What will we get if we take away three
We’re shown a ten frame with nine
counters. We have to take away three of them. One, two, three. How many counters are left in the ten
frame? There are six counters left. We had nine counters. We took away three. We got six. If we take away three from nine, we
will get six. Nine subtract three is six.
What have we learned in this video? We’ve learned how to read, write, and
model subtraction sentences using the subtraction symbol.
