1 Tens and Ones
Exercise 1
How do I break down the number 23 into tens and ones?
Difficulty: Beginner Time: ~2 minutes Skills: Place Value Recognition
Definition:

Place value: The value of a digit based on its position in a number. In 2-digit numbers, the rightmost digit is the ones place, and the leftmost digit is the tens place.

Note: Each place represents groups of 10. The tens place shows how many groups of ten, and the ones place shows how many individual units.

Step-by-step method:
  1. Identify the tens digit (leftmost digit in a 2-digit number)
  2. Identify the ones digit (rightmost digit in a 2-digit number)
  3. Convert each digit to its actual value (tens digit × 10, ones digit × 1)
  4. Express the number as the sum of its place values

2 tens = 20
3 ones = 3
23 = 20 + 3 = 2 tens + 3 ones
Step 1: Identify the digits

In the number 23, the digit 2 is in the tens place and the digit 3 is in the ones place

Step 2: Calculate the value of each place

The 2 in the tens place represents 2 × 10 = 20

The 3 in the ones place represents 3 × 1 = 3

Step 3: Express as sum of place values

23 = 20 + 3 = 2 tens + 3 ones

23 = 2 tens + 3 ones = 20 + 3
Final answer:

23 = 2 tens + 3 ones

Applied rules:

• Place value: Each position in a number has a specific value

• Tens place: Shows how many groups of ten are in the number

• Ones place: Shows how many individual units are in the number

• Practice Tip: Count the tens blocks and ones blocks separately to visualize the concept

Related Examples:
  • 45 = 4 tens + 5 ones = 40 + 5 - Practice with higher tens
  • 17 = 1 ten + 7 ones = 10 + 7 - Practice with single ten
  • 30 = 3 tens + 0 ones = 30 + 0 - Practice with zero ones
Quick Tips:
  • Count by tens first, then count the remaining ones
  • Use base ten blocks to physically represent the number
  • Remember: 1 ten equals 10 ones
Frequently Asked Questions:

Q: Can a number have more tens than ones?
A: Yes! For example, 52 has 5 tens and 2 ones. The number of tens and ones are independent of each other.

Q: What if I have 10 ones?
A: 10 ones equal 1 ten. So if you have 10 ones, you regroup them as 1 ten and 0 ones.

6 Comparing Numbers
Exercise 6
Which is greater: 34 or 43? Explain using place value.
Definition:

Number comparison: Determining which of two numbers is greater by comparing their place values, starting with the highest place value.

Note: When comparing numbers, we start with the leftmost digit (highest place value) and move right if the digits are equal.

Step-by-step comparison method:
  1. Compare the tens digits first (leftmost digits)
  2. If tens digits are equal, compare the ones digits
  3. Determine which number is greater based on place value
  4. Verify by considering the actual values of each number

3 tens + 4 ones = 30 + 4 = 34
43
4 tens + 3 ones = 40 + 3 = 43
34 = 3 tens + 4 ones
43 = 4 tens + 3 ones
Step 1: Compare the tens digits

In 34, the tens digit is 3. In 43, the tens digit is 4.

Since 4 > 3, the number with 4 in the tens place is greater.

Step 2: Consider the total value

34 = 30 + 4 = 34

43 = 40 + 3 = 43

Step 3: Determine which is greater

Since 43 > 34, the number 43 is greater than 34.

43 > 34
Final answer:

43 is greater than 34 because 4 tens (40) is greater than 3 tens (30).

Applied rules:

• Place value comparison: Start with the highest place value

• Greater than: 43 has more tens than 34

• Visualization: More tens blocks mean a larger number

• Practice Tip: Always compare place values from left to right

Related Examples:
  • 25 vs 52: 52 > 25 because 5 tens > 2 tens
  • 61 vs 16: 61 > 16 because 6 tens > 1 ten
  • 87 vs 78: 87 > 78 because 8 tens > 7 tens
Quick Tips:
  • Always start comparing from the leftmost (highest) place value
  • More tens always means a larger number (for 2-digit numbers)
  • If tens are equal, then compare the ones
Frequently Asked Questions:

Q: What if the tens are the same?
A: If the tens digits are equal, compare the ones digits. For example, 35 vs 32: since tens are equal, compare ones: 5 > 2, so 35 > 32.

Q: Why does the number with more tens seem bigger?
A: Because each ten represents 10 units, so having more tens gives a much larger value than having more ones.

Step 2: Identify what's being added

1 ten + 3 ones = 10 + 3 = 13

Step 3: Add tens with tens and ones with ones

Tens: 2 + 1 = 3 tens

Ones: 5 + 3 = 8 ones

Step 4: Combine to form the final number

3 tens + 8 ones = 30 + 8 = 38

25 + 13 = 38 = 3 tens + 8 ones
Final answer:

You now have 38, which is 3 tens and 8 ones.

Applied rules:

• Separate operations: Add tens with tens, ones with ones

• Place value: Keep track of each place separately

• Regrouping: If ones sum to 10 or more, regroup as tens

• Practice Tip: Use base ten blocks to visualize the addition

Related Examples:
  • 3 tens + 2 ones + 1 ten + 4 ones = 4 tens + 6 ones = 46
  • 1 ten + 7 ones + 2 tens + 2 ones = 3 tens + 9 ones = 39
  • 4 tens + 5 ones + 1 ten + 6 ones = 5 tens + 11 ones = 61 (regroup 10 ones as 1 ten)
Quick Tips:
  • Always add tens with tens and ones with ones separately
  • If you get 10 or more ones, regroup 10 ones as 1 ten
  • Use base ten blocks to model the problem if needed
Frequently Asked Questions:

Q: What happens if I get 10 or more ones?
A: You regroup! Every 10 ones become 1 ten. For example, if you have 12 ones, that's 1 ten and 2 ones.

Q: Why can't I just add the numbers normally?
A: You can! Adding 25 + 13 = 38. But understanding place value helps you see why the algorithm works.

Key Laws, Methods, Rules, and Definitions
23 = 20 + 3 = 2 tens + 3 ones
Place Value Decomposition
Key definitions:

Place value: The value of a digit based on its position in a number. In 2-digit numbers, the rightmost digit is the ones place, and the leftmost digit is the tens place.

Tens place: Represents groups of ten (10, 20, 30, etc.)

Ones place: Represents individual units (1, 2, 3, etc.)

Complete methodology:
  1. Analyze the number: Identify the digits and their positions
  2. Determine place values: Recognize tens and ones positions
  3. Apply the method: Separate into tens and ones or combine as needed
  4. Verify the result: Check that the parts add up to the original number
Tip 1: Use base ten blocks to visualize numbers - long blocks represent tens, small cubes represent ones.
Tip 2: Remember that 1 ten equals 10 ones - this is important for regrouping.
Tip 3: When comparing numbers, start with the tens place. More tens always means a larger number.
Tip 4: Always check your work by adding the tens and ones to make sure they equal the original number.
Common errors: Mixing up tens and ones, forgetting that position determines value, not just the digit itself.
Exam preparation: Practice identifying place values, converting between standard and expanded form, comparing numbers.
Key concepts to remember:

• Place value: Each position has a specific value (tens = ×10, ones = ×1)

• Expanded form: Writing numbers as the sum of their place values (45 = 40 + 5)

• Base ten: Our number system is based on groups of ten

• Regrouping: 10 ones can be exchanged for 1 ten

• Comparison: Start comparing from the highest place value (leftmost)

Questions & Answers

Question: I don't understand why the number 45 has 4 tens and 5 ones. Why doesn't the 4 represent 4 ones and the 5 represent 5 tens?

Answer: Great question! The position of each digit determines its value, not the digit itself:

  • The tens place is always the position to the left in a 2-digit number
  • The ones place is always the position to the right in a 2-digit number
  • In 45, the 4 is in the tens place, so it represents 4 tens (40)
  • In 45, the 5 is in the ones place, so it represents 5 ones (5)

Think of it like this: if you have 45 apples, you could organize them as 4 groups of 10 apples (40 apples) and 5 individual apples (5 apples).

Example: In 72, the 7 is in the tens place (70) and the 2 is in the ones place (2), so 72 = 70 + 2.

Question: My child is struggling with place value. How can I help them understand it better at home?

Answer: Here are effective strategies to support your child's understanding of place value:

  • Use manipulatives: Counters, base ten blocks, or even dried beans can represent ones and groups of ten
  • Real-world connections: Use money (dimes = tens, pennies = ones) or group everyday objects
  • Practice regularly: Spend 10-15 minutes daily on place value activities
  • Play games: Card games, dice games, or online math games that focus on tens and ones

Activities to try: Have your child build numbers with objects, play "guess my number" with place value clues, or use a hundreds chart to visualize number relationships.

Remember: Patience and repetition are key. Most children need multiple exposures to master place value concepts.

Question: Why do we learn about tens and ones? When will I use this?

Answer: Place value is super important because it helps you understand ALL numbers! Here's why:

  • It makes big numbers easier: Understanding 23 helps you understand 234 and 2,345
  • It helps with math: Adding, subtracting, multiplying, and dividing all use place value
  • Real life uses: Money, time, measurements, and shopping all involve place value
  • Future math: You'll need it for bigger numbers, decimals, and advanced math

Think of place value as the foundation of our number system - just like you need a strong foundation for a house, you need place value for all math!

Every time you count money, measure something, or read a clock, you're using place value without even knowing it!

Place Value Glossary

Place Value
The value of a digit based on its position in a number. In 2-digit numbers, the left digit is the tens place and the right digit is the ones place.
Tens Place
The position in a number that represents groups of ten. In 47, the 4 is in the tens place and represents 40.
Ones Place
The position in a number that represents individual units. In 47, the 7 is in the ones place and represents 7.
Base Ten Blocks
Physical or visual representations where a long block represents 10 units and a small cube represents 1 unit, helping visualize place value.
Expanded Form
Writing a number as the sum of the value of each digit based on its place value. Example: 34 = 30 + 4.
