CBSE Class 4 Maths Tick Tick Tick Worksheet Set 05

Competency: Problem Solving Ability

Question 1. Arrange the following numbers in ascending order: 412,521, 742,153, 356,800, 145,631
Answer: Given numbers = 412521, 742153, 356800, 145631
Comparing the numbers from the leftmost digits:
- 145631 has 1 in the lakhs place.
- 356800 has 3 in the lakhs place.
- 412521 has 4 in the lakhs place.
- 742153 has 7 in the lakhs place.
Arranging from smallest to largest: 145631, 356800, 412521, 742153
In simple words: Ascending order means arranging numbers from the smallest to the largest.

Exam Tip: Always compare the highest place value first (lakhs place here) when ordering large numbers.

Question 2. Arrange the following numbers in descending order: 511,621, 876,168, 133,666, 421,764
Answer: Given numbers = 511621, 876168, 133666, 421764
Comparing the numbers from the leftmost digits:
- 876168 has 8 in the lakhs place.
- 511621 has 5 in the lakhs place.
- 421764 has 4 in the lakhs place.
- 133666 has 1 in the lakhs place.
Arranging from largest to smallest: 876168, 511621, 421764, 133666
In simple words: Descending order means arranging numbers from the largest to the smallest.

Exam Tip: Check the sign or heading carefully to ensure you do not mix up ascending and descending order.

Question 3. How many triangles can you find in this figure?
Answer: The given figure is a Hexagram (Star of David), which is formed by two overlapping equilateral triangles.
- There are 2 large triangles (one pointing upwards and one pointing downwards).
- There are 6 small upright and inverted triangles formed at the outer tips.
Total number of triangles = 2 + 6 = 8
In simple words: Count the small triangles around the outer edges first, then add the two large overlapping triangles.

Exam Tip: For complex shape-counting puzzles, break the figure down into smaller distinct parts to avoid double-counting.
