This maths quiz for Class 6 covers the topics students meet in their first year of middle-school maths: prime numbers and factors, HCF and LCM, fractions, decimals, integers, angles, symmetry, perimeter and area, and number patterns. The 15 questions start easy and get harder, so a student can warm up with the basics before reaching the tricky ones at the end.
Each question is a maths MCQ with four options and a short explanation that shows the working, not just the answer. That makes it useful as a quick revision test before a unit test, a homework check, or a warm-up at the start of a maths class. Teachers can also project it for a whole-class round and let groups shout out answers.
Students who get a question wrong should read the explanation, try the same idea with different numbers in a notebook, and then play the quiz again. Parents can use the answer key below to go through the class 6 maths MCQ questions with answers together.
Fun fact to try: add up the odd numbers in order (1, then 1 + 3, then 1 + 3 + 5) and you always get a square number. Draw it with dots and you will see each new odd number wraps neatly around the last square.
Maths Quiz for Class 6 questions with answers
Show answers
What is the smallest prime number?
- 2
- 1
- 0
- 3
Answer: 2. 2 is the smallest prime and the only even prime. The number 1 is neither prime nor composite, because it has just one factor.
How many degrees are there in a right angle?
- 45 degrees
- 90 degrees
- 180 degrees
- 360 degrees
Answer: 90 degrees. A right angle is exactly 90 degrees, like the corner of a book. Two right angles together make a straight angle of 180 degrees.
A rectangle is 8 cm long and 5 cm wide. What is its perimeter?
- 13 cm
- 40 cm
- 26 cm
- 18 cm
Answer: 26 cm. Perimeter of a rectangle = 2 x (length + breadth) = 2 x (8 + 5) = 26 cm. 40 is its area in square cm, a common mix-up.
What is the area of a square with each side 7 cm long?
- 28 sq cm
- 14 sq cm
- 21 sq cm
- 49 sq cm
Answer: 49 sq cm. Area of a square = side x side = 7 x 7 = 49 sq cm. 28 cm would be its perimeter (4 x 7).
What is the successor of 99,999?
- 1,00,000
- 99,998
- 1,00,001
- 9,99,999
Answer: 1,00,000. The successor is the number just after, so add 1: 99,999 + 1 = 1,00,000, which is one lakh (100,000 in the international system).
Which fraction is equal to 1/2?
- 2/3
- 3/6
- 4/6
- 5/8
Answer: 3/6. Multiply the top and bottom of 1/2 by 3 and you get 3/6. Equivalent fractions name the same amount in different ways.
What is (-5) + 8?
- Minus 13
- 13
- 3
- Minus 3
Answer: 3. Start at -5 on the number line and move 8 steps to the right. You land on 3.
How many lines of symmetry does a square have?
- 1
- 2
- 8
- 4
Answer: 4. A square has 4 lines of symmetry: 2 through the midpoints of opposite sides and 2 along its diagonals. A rectangle (not a square) has only 2.
What is the LCM of 4 and 6?
- 12
- 24
- 2
- 10
Answer: 12. Multiples of 4 are 4, 8, 12... and multiples of 6 are 6, 12... The lowest common multiple is 12. 24 is common too, but not the lowest.
What is the HCF of 12 and 18?
- 3
- 6
- 2
- 36
Answer: 6. Factors of 12: 1, 2, 3, 4, 6, 12. Factors of 18: 1, 2, 3, 6, 9, 18. The highest common factor is 6.
Which of these is NOT a prime number?
- 13
- 29
- 21
- 17
Answer: 21. 21 = 3 x 7, so it has more than two factors and is composite. 13, 17 and 29 can only be divided by 1 and themselves.
Which of these decimals is the largest?
- 0.69
- 0.077
- 0.67
- 0.7
Answer: 0.7. Write them with the same number of places: 0.7 = 0.70, which is more than 0.69 and 0.67. 0.077 is the smallest.
Which number is divisible by 9?
- 8,163
- 1,234
- 5,672
- 2,341
Answer: 8,163. A number is divisible by 9 if the sum of its digits is. 8 + 1 + 6 + 3 = 18, and 18 is divisible by 9, so 8,163 = 9 x 907.
What is 3/4 + 1/8?
- 4/12
- 7/8
- 4/8
- 5/8
Answer: 7/8. Make the denominators the same: 3/4 = 6/8. Then 6/8 + 1/8 = 7/8. You never add the denominators.
What is the sum of the first 10 odd numbers (1 + 3 + 5 + ... + 19)?
- 50
- 81
- 100
- 110
Answer: 100. Adding odd numbers in order always gives a square number: 1 + 3 = 4, 1 + 3 + 5 = 9. So the first 10 odd numbers add up to 10 x 10 = 100.
