Problem Explanation and Solution
The worksheet focuses on understanding
place value and
digit value of numbers up to 1,000. Let's solve each section step by step.
---
####
Section A: Write the place value and digit value of the underlined digit
We need to identify the
place value (hundreds, tens, or ones) and the
digit value (the actual value of the digit in that place) for the underlined digits in the given numbers.
#####
Example:
- Number:
416
- Underlined digit:
6
- Place value:
ones
- Digit value:
6
#####
Solutions:
1.
a) 250
- Underlined digit:
2
- Place value:
hundreds
- Digit value:
200
2.
b) 310
- Underlined digit:
1
- Place value:
tens
- Digit value:
10
3.
c) 907
- Underlined digit:
9
- Place value:
hundreds
- Digit value:
900
4.
d) 629
- Underlined digit:
2
- Place value:
tens
- Digit value:
20

####
Section B: Partition each of the following numbers according to the digit value
We need to break down each number into its component parts based on the digit value of each place (hundreds, tens, and ones).
#####
Example:
- Number:
249
- Partition:
200 + 40 + 9
#####
Solutions:
1.
a) 306
- Partition:
300 + 0 + 6
2.
b) 452
- Partition:
400 + 50 + 2
3.
c) 692
- Partition:
600 + 90 + 2

####
Section C: Partition each of the following numbers according to the place value
We need to express each number in terms of its hundreds, tens, and ones places.
#####
Example:
- Number:
503
- Partition:
5 hundreds + 0 tens + 3 ones
#####
Solutions:
1.
a) 347
- Partition:
3 hundreds + 4 tens + 7 ones
2.
b) 551
- Partition:
5 hundreds + 5 tens + 1 ones
3.
c) 805
- Partition:
8 hundreds + 0 tens + 5 ones
