Adding Numbers to 10

In this video, we will learn how to
find the missing total in an addition sentence when we are adding numbers to 10. This is a part–whole model. One of the parts contains three
bricks. And the other part contains four
bricks. This circle shows the whole
amount. We could also call this the
total. What is the total of three and
four? It’s seven. Three plus four gives us a total of
seven. So to find the total in an addition
sentence, we need to add together both of the parts. Three plus four equals seven. The total is seven. Let’s practice adding to find the
total.

Add the following to find the total
number of sandwiches. Three plus two equals what.

To help us find the total. We could model the addition
sentence using some counters. We have three blue counters and two
orange counters. How many are there altogether? One, two, three, four, five. The total number of counters is
five, so the total number of sandwiches is five. Three plus two equals five.

What is the total number of
leaves? Five plus three equals what.

Let’s use a 10 frame to help us add
together five and three. Here are five counters; now, let’s
add three more. One more counter gives us six,
seven, eight. The total number of leaves is
eight. To find the total, we added
together five and three.

Five plus five equals what.

In this question, we’re being asked
to find the total of five plus five. We could place five counters into a
10 frame then add five more. Here are five orange counters and
five green counters. The 10 frame is full, which means
it has 10 counters. Five plus five gives us a total of
10.

What have we learned in this
video? We’ve learned how to add together
two amounts to find the total.
