Unit 1: Number Sense
Topic B: Place Value
As you know, we count much higher than ten in our world. Each place in a number has a value.
The ones place tells how many ones there are.
- 3 means 3 ones.
- 0 means 0 ones
- 9 means 9 ones
9 is the largest amount that we can express (write or say) with one digit.
The tens place shows how many tens there are. The ones place must have a digit in it before there can be a digit in the tens place.
Every ten is ten ones.
43 means 4 tens and 3 ones.
20 means 2 tens and 0 ones. The zero holds the ones place.
99 means 9 tens and 9 ones. 99 is the largest amount that we can express (write or say) using only two digits.
Fill in the blanks to make each sentence true. Draw a picture for questions c, f, h, and j like the examples. Check your work using the answer key at the end of the exercise. Ask your instructor to check your sketches.
Example
49 means 4 tens and 9 ones.
- 37 means tens and ones.
- 65 means tens and ones.
- 56 means tens and ones.
- 87 means tens and ones
- 33 means tens and ones.
- 60 means tens and ones.
Answers to Exercise 1
- 3 tens, 7 ones
- 6 tens, 5 ones
- 5 tens, 6 ones
- 8 tens, 7 ones
- 3 tens, 3 ones
- 6 tens, 0 ones
The place to the left of the tens place is the hundreds place. It shows how many hundreds there are. A number written using three whole digits has a hundreds place, a tens place, and a ones place.
Every hundred is the same as ten tens, and every hundred is the same as one hundred ones.
Every hundred is ten tens – every hundred is the same as one hundred ones.
100 100 100
425 means 4 hundreds, 2 tens, and 5 ones

How are you feeling?
- Are your palms moist?
- How is your breathing?
Take control. Be the boss. If you are feeling anxious, practice your breathing exercise.
Remember: Breathe in slowly to the count of four, hold it for the count of four.
You know that the digits are 0 1 2 3 4 5 6 7 8 9 and that digits are arranged in different places so we can count larger amounts than our ten fingers!
When we use digits, we call what we write the numeral.
- 328 is a numeral
- 46 is a numeral
- 3 is a numeral
We use numerals to represent numbers.
If we think about language instead of mathematics it will be clearer.
Letters are used to make words. We respond to the meaning of words.
- Digits are the “letters” of math.
- Numerals are the “words” of math.
- Numbers are the “meaning” of math.
Now you know the place value of digits up to three places. Next you will learn to read and write numerals and number words. Some of the words to read and spell may be new to you.
The numerals from 1 to 12 have special words. These are:
Numeral | Word Name |
---|---|
0 | zero |
1 | one |
2 | two |
3 | three |
4 | four |
5 | five |
6 | six |
7 | seven |
8 | eight |
9 | nine |
10 | ten |
11 | eleven |
12 | twelve |
The number names for numerals from 13 to 19 are made up of two parts. The first part tells us how many units. The second part (“teen”) tells us there is also 1 ten.
Numeral | Word Name | Meaning |
---|---|---|
13 | thirteen | three units and 1 ten |
14 | fourteen | four units and 1 ten |
15 | fifteen | five units and 1 ten |
16 | sixteen | six units and 1 ten |
17 | seventeen | seven units and 1 ten |
18 | eighteen | eight units and 1 ten |
19 | nineteen | nine units and 1 ten |
Write the word name for each number. Try not to look at the list. Check your work using the answer key at the end of the exercise.

- 13
Answers to Exercise 6

- fourteen

The word names for the numbers 20 to 90 are also made up of two parts. The first part tells us how many groups of tens. The second part (“ty”) tells us we are counting groups of tens and not something else. The “-ty” may have come from a shortening of the word “ten”.
Number | Word Name | Meaning |
---|---|---|
20 | twenty | two tens |
30 | thirty | three tens |
40 | forty | four tens |
50 | fifty | five tens |
60 | sixty | six tens |
70 | seventy | seven tens |
80 | eighty | eight tens |
90 | ninety | nine tens |
The names for the numbers between groups of tens also follow a pattern. The first number tells us how many tens. The second number tells us how many ones.
Tens Ones | Tens Ones | Tens Ones |
---|---|---|
20 twenty | 30 thirty | 40 forty |
21 twenty-one | 31 thirty-one | 41 forty-one |
22 twenty-two | 32 thirty-two | 42 forty-two |
23 twenty-three | 33 thirty-three | 43 forty-three |
24 twenty-four | 34 thirty-four | 44 forty-four |
25 twenty-five | 35 thirty-five | 45 forty-five |
26 twenty-six | 36 thirty-six | 46 forty-six |
27 twenty-seven | 37 thirty-seven | 47 forty-seven |
28 twenty-eight | 38 thirty-eight | 48 forty-eight |
29 twenty-nine | 39 thirty-nine | 49 forty-nine |

When we write hundreds in words, we need two words. The first word tells us how many hundreds. The second word tells us we are counting hundreds.
200 two hundred
You now know how to write numbers in words up to 999.
- hyphen (-) between the tens and units
- no hyphen anywhere else
- no “s” on the hundred
- no “and” between the hundreds place and the tens place
