Mental Math Strategies for Addition and Subtraction

When it comes to addition and subtraction, there are several effective mental math strategies that children can learn. These strategies not only improve calculation speed but also develop their overall mental math skills. Let’s explore some of these strategies:
  1. Counting On: Start with a larger number and count on by adding the smaller number. For example, for 7 + 3, start with 7 and count on 3: 8, 9, 10. This strategy helps children understand the concept of addition and mentally visualize the number line.
  2. Counting Back: Subtract a number from the total by counting back. This strategy is useful for subtraction. For example, for 15 – 8, start with 15 and count back 8: 14, 13, 12, 11, 10, 9, 8. This strategy strengthens subtraction skills and helps children see the relationship between addition and subtraction.
  3. Using Doubles or Near Doubles: Utilize known doubles or near doubles to simplify calculations. For instance, for 6 + 7, break it down into 6 + 6 + 1, which is easier to calculate mentally: 12 + 1 = 13. This strategy builds fluency in addition and enhances mental flexibility.
  4. Bridging Strategies to 10: Break down numbers to make them easier to add or subtract using the number 10. For example, for 8 + 6, children can bridge to 10 by adding 2 to 8 to make it 10 and then add the remaining 4: 10 + 4 = 14. This strategy empowers children to manipulate numbers and strengthens their mental math skills.
  5. Understanding Place Value While Partitioning: Decompose numbers into their place value parts to simplify calculations. For example, for 23 + 19, break it down into (20 + 3) + (10 + 9): 20 + 10 = 30, 3 + 9 = 12, so 30 + 12 = 42. This strategy reinforces the understanding of place value and improves mental computation.
By teaching and practicing these mental math strategies, children can develop their ability to perform addition and subtraction calculations mentally, improving their overall mathematical proficiency and boosting their confidence.
Strategy Example
Counting On 7 + 3 = 10
Counting Back 15 – 8 = 7
Using Doubles or Near Doubles 6 + 7 = 13 (6 + 6 + 1)
Bridging Strategies to 10 8 + 6 = 14 (10 + 4)
Understanding Place Value While Partitioning 23 + 19 = 42 (20 + 3) + (10 + 9)

Mental Math Strategies for Multiplication and Division

In addition to addition and subtraction, children can also learn mental math strategies for multiplication and division. These strategies utilize various techniques to make complex mathematical operations easier to perform mentally.

1. Repeated Addition/Subtraction

One effective strategy for mental multiplication and division is to break down the calculation into repeated addition or subtraction of the same number. For example:
  • Multiplication: To mentally calculate 6 x 7, you can repeatedly add 6: 6 + 6 + 6 + 6 + 6 + 6 + 6 = 42
  • Division: To mentally calculate 48 ÷ 6, you can repeatedly subtract 6: 48 – 6 – 6 – 6 – 6 – 6 – 6 = 8

2. Place Value Concepts

Understanding place value concepts can greatly simplify mental multiplication and division. By breaking down numbers into their digit values, you can perform calculations more efficiently. For example:
  • Multiplication: To mentally calculate 23 x 4, you can multiply the tens digit and the ones digit separately: (20 x 4) + (3 x 4) = 80 + 12 = 92
  • Division: To mentally calculate 72 ÷ 6, you can divide the tens digit and the ones digit separately: (70 ÷ 6) + (2 ÷ 6) = 11 + 0.33 (approximately) = 11.33 (approximately)

3. Factorization

Using factorization can make mental multiplication and division easier by breaking down numbers into their prime factors. By identifying common factors, you can simplify calculations. For example:
  • Multiplication: To mentally calculate 28 x 3, you can break down 28 into its prime factors (2 x 2 x 7) and multiply each factor by 3: (2 x 2 x 7) x 3 = 12 x 7 = 84
  • Division: To mentally calculate 72 ÷ 12, you can break down 72 and 12 into their prime factors (72 = 2 x 2 x 2 x 3 x 3 and 12 = 2 x 2 x 3) and divide the common factors: (2 x 2 x 2 x 3 x 3) ÷ (2 x 2 x 3) = 3

4. Commutative Property

The commutative property of multiplication allows you to rearrange the order of numbers without changing the result. This property can be helpful for mental calculations. For example:
  • Multiplication: To mentally calculate 7 x 6, you can use the commutative property to rearrange the numbers: 6 x 7 = 42
  • Division: To mentally calculate 48 ÷ 8, you can use the commutative property to rearrange the numbers: 48 ÷ 8 = 8
By employing these mental math strategies for multiplication and division, children can gain confidence in solving more complex mathematical problems without the aid of calculators or written calculations.

Mental math benefits and disadvantages

Disadvantages of Mental Math

While mental math has many advantages, there are also some potential disadvantages. One disadvantage is that mental calculations can be prone to errors, especially when dealing with large numbers or complex calculations. Mistakes in mental math can occur due to miscalculations or misinterpretation of the problem. Relying too heavily on mental math may also result in a lack of proficiency with written calculations or the use of calculators. It is important to strike a balance between mental math skills and other calculation methods to ensure that individuals are competent in various mathematical techniques. Moreover, mental math can be time-consuming for certain individuals. Complex calculations often require more time and effort compared to using written methods or calculators. This can be a drawback in situations where efficiency and speed are crucial, such as in time-sensitive exams or professional environments. It is worth noting that not all individuals have the same aptitude for mental math. Some people may find it more challenging to perform calculations mentally, which may lead to frustration and a lack of confidence in their mathematical abilities. Overall, while mental math offers numerous benefits, it is important to be aware of its potential drawbacks. By recognizing the limitations and striking a balance between mental math and other calculation methods, individuals can maximize the benefits while mitigating the disadvantages.

Memory and Working Memory in Mental Math

Mental math is not only about the ability to perform calculations in your head, but it also relies heavily on memory skills. Strong memory and working memory capacities play crucial roles in mastering mental math skills. When solving math problems mentally, you need to retrieve math facts and number concepts from your long-term memory. This includes recalling basic arithmetic facts, such as addition and multiplication tables, as well as understanding number relationships and patterns. The more you practice mental math, the more these math facts become ingrained in your memory, allowing you to access them quickly and effortlessly. Working memory, on the other hand, refers to the ability to hold and manipulate information in your mind for short periods of time. In mental math, working memory is essential for keeping track of the steps involved in a calculation and carrying out the necessary operations mentally. It involves mentally organizing the numbers, applying mathematical operations, and storing intermediate results. With practice, you can enhance your working memory capacity and improve your efficiency in mental calculations. Developing strong memory and working memory skills can have broader benefits beyond mental math. Memory is a fundamental aspect of learning, and improving your memory capacities can enhance overall cognitive abilities, such as learning new concepts, problem-solving, and critical thinking. Furthermore, working memory skills are valuable in various academic and professional tasks that require holding and manipulating information mentally. So, if you want to excel in mental math and reap its benefits, it’s essential to focus on strengthening your memory and working memory capacities. Regular practice and repetition of mental math exercises can help consolidate math facts in your memory and improve your ability to solve math problems mentally.
