Problem Explanation and Solution
The worksheet focuses on
place value concepts, where numbers are broken down into their respective place values (thousands, hundreds, tens, and ones). Let's solve each section step by step.
---
####
Section 1: Partition the Numbers
We need to split the given numbers into thousands, hundreds, tens, and ones.
1.
2345
- Thousands: 2000
- Hundreds: 300
- Tens: 40
- Ones: 5
This is already filled in correctly.
2.
9876
- Thousands: 9000
- Hundreds: 800
- Tens: 70
- Ones: 6
3.
4230
- Thousands: 4000
- Hundreds: 200
- Tens: 30
- Ones: 0
4.
1010
- Thousands: 1000
- Hundreds: 0
- Tens: 10
- Ones: 0

####
Section 2: Write the Answers to Place Value Additions
We need to add the given place values to form the complete number.
1.
6000 + 700 + 20 + 8
- Thousands: 6000
- Hundreds: 700
- Tens: 20
- Ones: 8
- Total: \( 6000 + 700 + 20 + 8 = 6728 \)
(This is already filled in correctly.)
2.
7000 + 600 + 9
- Thousands: 7000
- Hundreds: 600
- Tens: 0
- Ones: 9
- Total: \( 7000 + 600 + 9 = 7609 \)
3.
3000 + 20
- Thousands: 3000
- Hundreds: 0
- Tens: 20
- Ones: 0
- Total: \( 3000 + 20 = 3020 \)
4.
800 + 90 + 1
- Thousands: 0
- Hundreds: 800
- Tens: 90
- Ones: 1
- Total: \( 800 + 90 + 1 = 891 \)

Section 3: Look at the Flowers
The flowers represent different place values:
- Red flower: 2000 (thousands)
- Purple flower: 600 (hundreds)
- Yellow flower: 50 (tens)
- Orange flower: 8 (ones)
We need to write the numbers with
5 tens that can be made by adding combinations of these flowers.
1.
Adding two yellow flowers (each representing 50):
- \( 50 + 50 = 100 \)
- This gives us 1 hundred, which is not 5 tens. So, this combination does not work.
2.
Combining other flowers to get exactly 5 tens (50):
- We need to find a combination that sums to 50.
- The only way to get exactly 50 is by using one yellow flower (which represents 50).
Thus, the number with
5 tens is simply
50.

Final Answers:
1.
Partition the Numbers:
- 9876: 9000 + 800 + 70 + 6
- 4230: 4000 + 200 + 30 + 0
- 1010: 1000 + 0 + 10 + 0
2.
Place Value Additions:
- 7000 + 600 + 9 =
7609
- 3000 + 20 =
3020
- 800 + 90 + 1 =
891
3.
Flowers Combination:
- The number with 5 tens is
50.

Boxed Final Answers:
\[
\boxed{
\begin{array}{l}
\text{1. Partition:} \\
9876 = 9000 + 800 + 70 + 6 \\
4230 = 4000 + 200 + 30 + 0 \\
1010 = 1000 + 0 + 10 + 0 \\
\\
\text{2. Place Value Additions:} \\
7000 + 600 + 9 = 7609 \\
3000 + 20 = 3020 \\
800 + 90 + 1 = 891 \\
\\
\text{3. Flowers Combination:} \\
50
\end{array}
}
