Why Should Children Do Math Puzzles?  

The best educational experience combines fun with learning. It is while having fun that humans learn the best. Puzzles make math learning fun because it involves a sense of challenge, and needs some amount of thought as one digs deep to connect knowledge and creativity to arrive at results that may surprise even the thinker. The euphoria that follows is always stimulating the child to do more. 

By engaging your child with puzzles, you develop their mathematical thinking and show them ways to apply creativity in tackling challenging problems. As you tackle puzzles together, the familial bond will make puzzle time a fun activity that your children will treasure forever. 


Strategies to Solve Maths Puzzles For Class 3

  1. First and foremost, understand the problem at hand and see if you can reword it in a simple manner. Alternatively, see if it can be represented in the form of a diagram or a table. Such an expression would help your child to think about the problem in hand from different angles.

  2. Please try to associate the problem with similar ones that the child had done before. That may trigger some correlation in the child’s mind.

  3. See if using physical manipulatives like paper or marbles could help the child visualize the problem better.

  4. Encourage logical reasoning to eliminate some options and narrow down solutions.

  5. Try to narrow down complexity and work with simpler logic or numbers and see if that could give some insight.

  6. The right attitude is most important to problem-solving. Appreciate a child’s success in pattern identification or estimation. Any new insights they gain is a step forward in the right direction.

  7. Help develop problem-solving perseverance by acknowledging their effort and encouraging them to go the extra mile.


Math Puzzles for Class 3 With Answers

Addition Puzzle Through Shapes:

Addition Math Puzzle 1:


Addition Math Puzzle
 

Answer: Each shape can be associated with a number.

Two triangles are equal to 4. So one triangle is equal to 2.

A triangle and a circle equal to 5. Since a triangle is 2, the circle is 3.

On similar lines, a square is 5 and a diamond is 4.

 

Therefore, the first set can be written as 2 +3+5 = 10

The second set can be written as 3+5+4 = 12

Further, the third set can be written as 2+3+5+4 = 14

First set = 10

Second set = 12

Third set = 14

 

Addition Math Puzzle 2:


Addition Math Puzzle

Answer: This puzzle involves associating numbers to shapes. Since the first set has 3 shapes, it can be connected with 3 numbers. So, the circle is 3, the square is 1 and the triangle is 2.

Following a similar line of reasoning, the star is 4. The diamond is 5.

The numbers to be added are 324+152 =  476.

Puzzles Involving Arithmetic Operations for Grade 3

Math Puzzle 3:


puzzle on trees

Answer: This problem can be solved easily if we narrow it down to a simpler problem. Ask your child to imagine 5 trees with a total distance of 20 m between them. Notice that 5 trees will have 4 gaps between them. The distance between two adjacent trees will then be 20 m divided by 4 gaps equal to 5 m. 

Extending this line of reasoning, we can see that 100 trees will have 99 gaps. Distributing 495m among 99 gaps will give us 5m as the length of each gap or the distance between the trees.

The distance between the trees is 5m.

 

Addition Math Puzzle 4:

Addition Math Puzzle

Answer:

  1. Engine = 25 metres

  2. 20 coaches = 20*40=800 metres

  3. 20 connectors = 20 metres

Therefore the total length of the train = 25 +800+20 = 845 metres

Addition Puzzles In Crossword Format

Math Puzzle 5:

Addition Puzzles In Crossword Format

Answer: The technique here is to assess if a pattern can be identified by applying a basic operation such as addition, subtraction, multiplication, or division.

Since there are numbers in a circle we can try the addition operation. This gives us a sum of 20 in 3 circles. Thus the fourth circle must add to 20 as well. Hence the missing value is 1.

The missing value is 1.

 

Math Puzzle 6:

Math Puzzle

Answer: Since 10 + 5 =15, try to place 5 in the middle cell. Now list the set of numbers that add up to 10.

These can be arranged in symmetrically opposite positions with respect to the central cell. 

1+9=10,2+8=10,3+7=10,4+6=10

The placement of the pairs with respect to each other also matters. The final solution can look like this. In the table below, each row and each column along with the diagonal adds up to 15.

8 1 6
3 5 7
4 9 2

Math Puzzle 7:

Math Puzzle
 

Answer: Vagmi has blocks 1,7,9 as their product is 63. That is the only combination possible.

Prerna has either blocks (2,8,3) or (2,4,6). Both give a product of 48.

Aditi has sum 16.

If Prerna has (2,8,3) then Aditi can only have 4+5+6 = 15 and not 16

If Prerna has (2,4,6) then Aditi can only have 8+5+3 = 16

Therefore, Prerna has (2,4,6) while Aditi has (3,5,8).

Math Puzzle 8:

Math Puzzle

 

Answer: Try to write the different factors (building blocks) of 12. They can then be combined in different ways to give us 12.

The factors of 12 are 1,2,3,4,6 and 12.

The triplet (1,2,6) combined to give 12 in 6 different ways  (126),(162),(216),(261),(612),(621).

Another triplet (1,3,4) combined to give 12 in another 6 ways. (134),(143),(314),(341),(413),(431)

Another combination is (2,2,3) for which the corresponding numbers are 223,322,232.

Thus 15 such numbers are possible.

 

Ken ken:

Math Puzzle 9:

Ken ken

Answer: Ken ken is a great way to enable children to do mental arithmetic. They develop the skill to evaluate all possible options before arriving at the right solution. 

Each row and column should have numbers from 1 to 4. The only number remaining to be filled in cell B1 is 2.This means B2 is 3 as B1 and B2 should add to 5.

1 and 2 need to be put in Row A. B3 must get 1 to get a sum of 4. This means, A2 is 1 and A3 is 2. It also makes B4 equal to 4.

D3 is a 3 and D4 is a 2. These are the numbers missing and they should add to 5.

C row can now be filled by elimination. C2 is 2, C3 is 4 and C4 is 1.


Logical Puzzle - Math Puzzle for Class 3

These help children to build deductive reasoning skills. It would enable them to build, analyze statements, sort through data, and draw reasonable conclusions. All are vital skills to develop Math ability.

Math Puzzle 10:

Logical Puzzle

Answer: Make a list of the handshakes by each person. While each person makes 3 handshakes, a handshake by red to yellow is the same as yellow to red. 

Removing repetitions will leave us with 6 handshakes.

There are 6 handshakes.

 

Math Puzzle 11:

puzzle

 

Answer: The way to analyze this puzzle is to first determine the number of people. Are there 4 people in all or is it possible to have a combination of two fathers and two sons with only 3 people?

In fact, there are only 3 people. G, being the father, gives his son F ₹200. Now, F is another father who gives his son ₹150. F is left with ₹50. Therefore F and S together have ₹ (50+150) =  ₹ 200.

F and S together have ₹ (50+150) =  ₹ 200.

Math Puzzle 12:

Math Puzzle
 

Answer: The doors can be named A, B, C, D, E, F, G. Suppose Anisha enters the room through Door - A, the list of entry door-exit door pairs will be AB, AC, AD, AE, AF, AG. Approaching the problem this way will help the child see a pattern in the number of options for each door. 

The 7 different doors will have 6 combinations each. This gives a total of 7*6=42 combinations.

Total of 7*6=42 combinations..

Spatial Puzzles - Math Puzzle for Class 3

These puzzles build strong visual-spatial ability in children. This ability helps them visualize relationships between objects, mentally rotate, and transform them. This builds essential skills that are required in a number of STEM professions.

 

Math Puzzle 13:

Spatial Puzzles

 

Answer: The first thing we can notice is that the pattern is symmetrical. It would be useful to draw the line of symmetry for these figures and see if that can reveal the underlying pattern.

If we draw the line of symmetry it will be apparent that the first figure is number 1. The second figure is number 2, the third figure is number 3 and the 4th figure is number 4. Similarly, clubbing numbers 5 and 6 will give us the next two patterns.

 

Math Puzzle 14:

Spatial Puzzles

Answer: The key to this puzzle is to understand that an ant crawls. So, as it moves from point A to point B it will navigate in both horizontal and vertical directions.

The solution to this puzzle is very simple and elegant. In getting from A to B, the ant takes a number of horizontal steps and a number of vertical steps. The sum of all the horizontal steps should be 6 metres. This is the total ‘horizontal shift’ in moving from A to B. Similarly, the sum of all the vertical steps should be 3 metres. This is the total ‘vertical shift’ in moving from A to B.

Since the sum of all the horizontal and vertical steps is 6+3=9 metres, the ant will crawl a total distance of 9 metres.

The ant will crawl a total distance of 9 metres.

Math Puzzle 15:

Spatial Puzzles

Answer: Think of how you can change the operation to make it work.

Take away the top right matchstick of 8 and use it to change the minus sign to a plus sign. Therefore the correct solution will be 9+6 = 15 which makes the equation true.

9 + 6 = 15


Conclusion

Math puzzles for class 3 can be a good activity to be taken up during family time. Discussing the puzzle, guiding them to see alternatives, allowing your child to explore different solutions will not only build a good relationships between the family members but will also ensure cognitive development of your child.
