This lesson teaches us to measure the size of different geometrical shapes with the help of a square
Introduction to CBSE Solutions for Class 5 Mathematics: How Many Squares?
This intriguing chapter invites students to dive into the world of squares, fostering their counting and analytical skills. “How Many Squares?” is not just about identifying individual squares but also about recognizing patterns and understanding how smaller squares can combine to form larger ones. The chapter illustrates the difference between single squares and composite squares, reinforcing the students’ understanding of area and how shapes can overlap and interact.
Students will engage in activities that challenge them to count the number of squares within a given grid, encouraging them to devise strategies and look beyond the obvious. They’ll discover that geometry is not only about figures and measurements but also about thinking logically and solving problems creatively.
By examining various square grids and learning to count the squares in multiple ways, students build a strong foundation in spatial reasoning and geometric concepts. The chapter also touches upon multiplication as a method for counting squares, linking it to the broader concepts of arithmetic.

Questions and Answers for CBSE Class 5 Mathematics: How Many Squares?
- Q1: What is a square?
ANS: A square is a four-sided polygon with equal sides and every angle at 90 degrees. - Q2: How do you find the total number of squares in a 3×3 grid?
ANS: In a 3×3 grid, there are 9 single squares, 4 squares made of 2×2 grids, and 1 square of the 3×3 grid itself, totaling 14 squares. - Q3: If each side of a square is 5 units long, what is its area?
ANS: The area is 25 square units (5 units x 5 units). - Q4: Can two squares overlap? If yes, how?
ANS: Yes, two squares can overlap by sharing a common side or part of their sides. - Q5: How many 2×2 squares can you find in a 4×4 grid?
ANS: There are 9 2×2 squares in a 4×4 grid. - Q6: What is the difference between a square and a rectangle?
ANS: A square has all sides equal and every angle at 90 degrees, while a rectangle has opposite sides equal and every angle at 90 degrees. - Q7: Is it possible to have a square with no right angles?
ANS: No, by definition, a square must have four right angles. - Q8: If you have four squares of area 1 square unit each, can you make a bigger square?
ANS: Yes, you can arrange them to form a bigger square with an area of 4 square units. - Q9: How many squares are there in a chessboard?
