## Mental Math Practice for All Levels

We have worksheets available to help students at all stages of their education develop good mental math skills.

Our materials contain tips and techniques for fast multiplication and division, and plenty of questions for students to practice their skills.

### Why Mental Math is Still Relevant?

In everyday life, most of us will instantly reach for a calculator when we need to do any sort of mathematical function.

We were all taught to do addition, subtraction, multiplication and addition in our heads in school, yet we rarely use this on a day to day basis. So it is a reasonable question to ask, is mental math still relevant?

### Practical use of Mental Math Techniques

Mental method is important as it helps students to estimate the final values of a sum.

Yes, they may use a calculator to reach that answer in some cases, but their mental math knowledge will tell them if their answer is correct or not. It is easy to make a mistake and produce an incorrect answer when using a calculator, so it is always best to have an idea of what the correct answer should be before inputting a sum into a calculator.

### Benefit of Learning Mental Math Methods

Our section of mental method worksheets provide an excellent resource for teachers and parents wanting to support students’ learning. With our mental math worksheets you can help your child or pupil become confident with mental math and learn a range of math facts.

Mental math has been said to build up brain muscle, and arithmetic questions have been said to help people of all ages improve their cognitive functions. Learning to perform calculations mentally helps children improve their memory, concentration and logic; by becoming confident at mental methods from an early age, children will be better prepared for answering more complicated math questions as they progress through education.

### WHAT IS MENTAL MATH? IS THERE A DEFINITION?

Mental math is a group of skills that allow us to do calculations in our heads. By remembering facts, we often use these methods to make a quick calculation without using paper and a pen, or without using the calculator in our phones.

We are using these skills every day to determine the most basic things like:

• Will I have enough money to buy this shirt and still have enough to buy lunch at school?
• How much time will it take me to get to the park on foot? When should leave to get there on time?
• Is the cashier giving me the right amount of change?

### WHY THIS METHOD IS HELPFUL FOR KIDS?

By using and practicing this type of math regularly kids can improve their number sense. For example:

If one chocolate bar is 2.5\$, and a package of 5 pieces is 10\$, kids can easily use this method to determine which offer is a better choice. To buy 5 individual chocolate bars the kid can quickly estimate that the cost is 12.5\$ and the package costs less.

Kids can also use mental math to get the right answer to a simple math question. For example:

What is 36 + 72? In our head we can quickly break the numbers down into digits values:

30 + 70 = 100

6 + 2 = 8

If we add this together we get 108.

### HOW TO DEVELOP MENTAL MATH CAPABILITY?

There is no simple way or trick to developing the capability quickly. There are no series of steps you can follow because this method means that you will need a real understanding of math. With time and practice, kids develop skills, which will help them manipulate numbers to make equations easier to solve.  Basically, the goal should be for kids and pupils to practice and construct their understandings. Students need to be flexible when it comes to solving problems, so that’s why they should learn not just memorize.
