Making Teen Numbers with Tens and
Ones
In this video, we will learn how to
decompose or break apart the numbers 11 to 19 into a ten and some ones. Here are the numbers 11 to 19: 11,
12, 13, 14, 15, 16, 17, 18, 19. We can make teen numbers from a ten
and some ones. This is a ten frame. It’s full of counters. So, there are 10 counters. We can call this a ten. We can call these counters
ones.
We have a ten and a one. 10 and one more is 11. We can decompose the number 11 or
break it into two parts. 11 has a ten and a one. We can break number 12 into a ten
and two ones. 10 and three ones makes 13, 14, 15,
16, 17, 18, 19.
Sophia used base ten blocks to
make a number. How many ones are there? What is the number?
We know Sophia has used base
ten blocks to make a number. She has one ten. How many ones are there? Let’s count. One, two, three, four, five,
six, seven, eight. What is the number? We have one ten and eight
ones. 10 and eight more is 18. Sophia’s number is number
18.
Decompose this number to
complete the number bond.
We have to decompose or break
apart this number to complete the part whole model. We know the number is number
16. 16 is 10 and some ones. We have to work out how many
ones. Here’s our 10. Let’s add ones until we reach
16. 11, 12, 13, 14, 15, 16. We’ve added six ones. A ten and six ones makes
16. The missing number is number
six. We broke apart the number 16
into a ten and six ones.
Look at how Sophia has made the
number 13 from tens and ones. 13 is one ten and three ones. 13 is one ten and three
ones.
What number does this table
show?
The table is called a place
value table. It shows the number of tens and
ones in our number. Our number has a ten. Let’s count the ones. There are one, two, three,
four, five, six. Our number has a ten and six
ones. Let’s count forward six from
number 10. 11, 12, 13, 14, 15, 16. A ten and six ones makes the
number 16. The table shows the number
16.
What have we learned in this
video? We’ve learned how to decompose or
break apart the numbers 11 to 19 into a ten and some ones.
