Shortcut Trick for Maths Calculation - For Class 1 and 2
-
The "Plus One, Minus One" Trick (Addition & Subtraction by 1)
-
Concept: This isn't a "trick" as much as a visual aid to solidify the concept of adding and subtracting one.
-
How it Works: For addition, ask them to think of the next number. For subtraction, ask for the previous number.
-
Example: "What is 5 + 1?" (Think: The next number after 5 is 6). "What is 7 - 1?" (Think: The number before 7 is 6).
-
Why it Helps: Reinforces the number line concept and the relationship between consecutive numbers.
-
Counting On/Counting Back (Addition & Subtraction):
-
Concept: Instead of counting all items, start from the larger number and count on.
-
How it Works (Addition): For 3 + 5, start at 5 and count "6, 7, 8" (three more).
-
How it Works (Subtraction): For 8 - 3, start at 8 and count back "7, 6, 5" (three back).
-
Why it Helps: Develops mental computation and reduces reliance on finger counting for larger numbers.
-
Friends of Ten (Number Bonds to 10):
-
Concept: This is foundational for later addition and subtraction. Knowing pairs of numbers that add up to 10.
-
How it Works: Ask "What number goes with 7 to make 10?" (Answer: 3). Use visual aids like ten frames or number lines.
-
Why it Helps: Crucial for efficient addition strategies (e.g., making a 10 and adding the rest).
Easy Math Tricks - For Class 3, 4, and 5
-
The "Zero" Trick (Multiplying by 10, 100, 1000)
-
Concept: Understanding place value shifts when multiplying by powers of 10.
-
How it Works: Simply add the number of zeros from 10, 100, or 1000 to the end of the other number.
-
Example: 7×10=70 (add one zero). 15×100=1500 (add two zeros).
-
Why it's Great: Makes large multiplications seem incredibly easy and reinforces the power of place value.
4. The "Doubles" Trick (Multiplying by 2)
-
Concept: Multiplying a number by 2 is the same as adding the number to itself.
-
How it Works: To find 6×2, just think 6+6=12. For 9×2, think 9+9=18.
-
Why it's Great: Connects multiplication to a familiar concept (addition), making the multiplication facts for 2 easy to grasp and recall.
-
The "Number Next Door" Trick (Multiplying by 9 with Fingers)
-
Concept: A fun, visual, and tactile way to instantly get multiplication facts for 9 (up to 10×9).
-
How it Works: Hold both hands out. For 9×4, fold down your 4th finger from the left. The fingers to the left of the folded finger are tens (3 fingers = 30). The fingers to the right are ones (6 fingers = 6). So, 9×4=36.
-
Why it's Great: It's incredibly engaging and provides an instant answer, helping children memorize the often-tricky 9s multiplication table.

6. Addition by "Make a Ten"
-
Concept: Using the "Friends of Ten" concept to simplify addition sums involving numbers close to 10.
-
How it Works: For 7+6, think: "7 needs 3 to make 10. Take 3 from 6, which leaves 3. So, 10+3=13."
-
Why it's Great: This is a fundamental mental math strategy that significantly speeds up addition and reduces errors.
7. Estimating Answers (Rounding)
-
Concept: Quickly finding an approximate answer to check if a precise calculation is reasonable.
-
How it Works: Round numbers to the nearest 10 or 100 before performing the operation. For 47+23, think 50+20=70.
-
Why it's Great: Develops strong number sense and helps students identify errors in their calculations.
8. Subtracting from 1000 (or other powers of 10)" Trick
-
Concept: A quick way to subtract any number from 100, 1000, 10000, etc.
-
How it Works: Subtract every digit from 9, except the last digit, which you subtract from 10.
-
Example: 1000−473
-
9−4=5
-
9−7=2
-
10−3=7
-
So, 1000−473=527.
-
Why it's Great: Makes subtraction across multiple zeros much faster and less prone to borrowing errors.
9. The "Break Apart" Method for Multiplication (Distributive Property)
-
Concept: Breaking down one of the numbers into easier parts (tens and ones) to multiply separately.
-
How it Works: For 13×7, think: (10×7)+(3×7)=70+21=91.
-
Why it's Great: Teaches the fundamental distributive property in a practical way, making multi-digit multiplication less intimidating. It's the mental math equivalent of the standard algorithm

10. Identifying Multiples (Divisibility Rules - simple ones)
-
Concept: Quick tests to see if a number is perfectly divisible by another.
-
How it Works:
-
By 2: If the last digit is even (0,2,4,6,8).
-
By 5: If the last digit is 0 or 5.
-
By 10: If the last digit is 0.
-
By 3: (Slightly more advanced) If the sum of its digits is divisible by 3. (e.g., For 21, 2+1=3, so 21 is divisible by 3. For 141, 1+4+1=6, so 141 is divisible by 3).
-
Why it's Great: Helps in simplifying fractions, understanding prime and composite numbers, and checking division answers.
Note - These tricks, when combined with hands-on activities and more xamples, can truly transform a child's perception of mathematics, making it an exciting and achievable subject. Remember, the key is to make learning playful and to celebrate every step of their mathematical journey!
