CBSE Class 4 Maths Place Value Puzzles Worksheet

PLACE VALUE PUZZLE

Solve the puzzle using the given hints and form the number-

Question 1. Write the number that comes between 6 and 8 at thousands place
Answer: The number between 6 and 8 is 7. Therefore, place 7 at the thousands place.
In simple words: The counting number that lies between 6 and 8 is 7.

Exam Tip: Identify place values correctly from right to left: Ones, Tens, Hundreds, Thousands, Ten Thousands, Lakhs, Ten Lakhs.

Question 2. Add 2 to number of days in a week and fill the answer at ones place
Answer: Number of days in a week = 7
Adding 2 to 7 gives \(7 + 2 = 9\). Therefore, place 9 at the ones place.
In simple words: A week has 7 days, and adding 2 makes it 9 for the ones place.

Exam Tip: Read basic calendar facts carefully before performing addition.

Question 3. Multiply 2 with 0 and write the answer at tens place
Answer: Multiplying any number by 0 gives 0. Therefore, \(2 \times 0 = 0\), and 0 is placed at the tens place.
In simple words: Any number multiplied by zero results in zero.

Exam Tip: Remember the zero property of multiplication: \(n \times 0 = 0\).

Question 4. Multiply the number at ones place with 1 and fill the hundreds place
Answer: The number at the ones place is 9.
Multiplying 9 by 1 gives \(9 \times 1 = 9\). Therefore, place 9 at the hundreds place.
In simple words: Any number multiplied by 1 remains the same.

Exam Tip: Link answers from previous steps sequentially as requested by the puzzle.

Question 5. Write the number of sides a triangle has at ten thousands place
Answer: A triangle has 3 sides. Therefore, place 3 at the ten thousands place.
In simple words: A standard triangle is a polygon with 3 sides.

Exam Tip: Recall basic geometric shapes and their properties.

Question 6. Divide the number of months in a year with 6 and write the answer at lakhs place
Answer: Number of months in a year = 12
Dividing 12 by 6 gives \(12 \div 6 = 2\). Therefore, place 2 at the lakhs place.
In simple words: There are 12 months in a year, and dividing by 6 gives 2.

Question 7. Subtract 5 from your age and write the number at ten lakhs place
Answer: Assuming a typical Class 4 student age is 10 years:
\(10 - 5 = 5\). Therefore, place 5 at the ten lakhs place.
In simple words: Subtract 5 from your current age to find the digit for the ten lakhs place.

Exam Tip: This is a variable personal puzzle hint; standard age 10 gives 5.

Question 8. Find the sum of place value of number at hundreds place and lakhs place
Answer: The formed 7-digit number is 5237909.
Digit at hundreds place = 9, so its place value = \(9 \times 100 = 900\)
Digit at lakhs place = 2, so its place value = \(2 \times 100000 = 200000\)
Sum = \(200000 + 900 = 200900\)
In simple words: Find the value represented by the digits in the hundreds and lakhs positions and add them together.

Exam Tip: Place value is the digit multiplied by its position value (e.g., hundreds = digit \(\times\) 100).

DRAWING ABACUS

Question 9. Draw an Abacus whose horizontal base line should be 8cm long and vertical bars should be 5 cm each and represent the number 23,456 on it.
Answer: To represent the number 23,456 on the abacus, draw 5 vertical bars representing Ten Thousands (TTH), Thousands (TH), Hundreds (H), Tens (T), and Ones (O) on an 8 cm horizontal base line, with each bar 5 cm tall.
- Ten Thousands bar: Draw 2 beads.
- Thousands bar: Draw 3 beads.
- Hundreds bar: Draw 4 beads.
- Tens bar: Draw 5 beads.
- Ones bar: Draw 6 beads.
In simple words: Draw a base line with 5 vertical sticks and place the correct number of bead rings on each stick according to the digits of 23,456.

Exam Tip: Ensure each vertical rod is clearly labeled with its respective place value abbreviation (TTH, TH, H, T, O).
