Making Three and Four
In this video, we will learn how to
use pictures and addition equations to show the different ways to make three and
four. Let’s start with the number
three. Here are three cupcakes. If we have two different plates,
how many ways can we make three? This plate has no cupcakes, but
this plate has three. We put all the cupcakes on the same
plate. Our addition sentence tells us that
zero plus three makes three. We found one way to make three. Zero plus three equals three.
Now we’ve moved one of the cakes
onto the other plate. On the first plate, we have one
cupcake, and on the other plate, we have two. One plus two makes three. Zero plus three equals three and
one plus two equals three. We found two different ways to make
three. Two and one makes three. Our addition sentence would say two
plus one equals three.
We found three different ways to
make three so far. If we put all the cupcakes on the
first plate, there are three and zero on the other. Three and zero makes three. We found four different ways to
make the number three: zero plus three, one plus two, two plus one, and three plus
How many ways can we make the
number four? If we put all of the green blocks
in the first group and none in the second, we can say that four plus zero makes
four. And if we write our addition
sentence down, it would say four plus zero equals four.
We found one way to make the number
four. Three plus one makes four. Two plus two is four. One plus three equals four. And zero plus four equals four. We found five different ways to
make four: four plus zero, three plus one, two plus two, one plus three, and zero
Let’s practice finding different
ways to make three and four with some questions.
There are three elephants. Zero plus three is three. Fill in the missing numbers to find
another way to get three. What plus what is three?
In the first picture, there’s one
elephant. And in the second picture, there
are one, two elephants. One plus two is three. The missing numbers are one and
two. Zero plus three is three and one
plus two is three.
Find the missing number to make
three. One plus what is three?
We know that there’s one red
counter. How many orange counters are
there? One, two. The missing number is two. One plus two is three.
Charlotte has shown one way to make
four. Write the addition expression that
matches the model.
There’s one red brick and one, two,
three green bricks. One plus three is four. The addition expression that
matches the model is one plus three.
What have we learned in this
video? We’ve learned that we can use
pictures and addition expressions to find different ways to make the numbers three
