There is a debate about how often young math students should be allowed to use a GPA Calculator. On one side of the argument, people say that you shouldn't use handheld calculators at all until you're a certain age; At an arbitrary level, students are now "entitled" or "old enough" to use calculators for their math homework. At the other extreme, some homeschool or classroom teachers allow their students to use calculators for everything. How to properly use a calculator when teaching (or learning) mathematics?

There isn't much discussion about what can happen when kids use calculators too much and too quickly. They become addicted to it and become mathematically lazy. By allowing the calculator to do a simple operation: 13 x 3, students may get confused and mistakenly assume the answer on the screen is correct. However, there are several reasons why math students should use a calculator. It can be appropriately enabled by classroom teachers or homeschool teachers to enhance the four aspects of math development.

Calculators can help clarify concepts

The ability to enter numbers and complex operations is sometimes an advantage when learning number patterns or rules. A calculator can be used to show that multiplying by an increasing number gives larger answers; Multiplying by a sum between zero and one gives the smallest answer. Teachers can show the repeating patterns of decimals and their relationship to fractions. When studying the graph of a function of a linear equation, students can enter different values ​​or slope factors to see how the graphs change. The speed of the tool greatly improves the detection of numerical patterns or bases. This would be an advantage when learning algebra, for example.

Calculators can help in real-world applications

For example, if students need to measure dimensions and apply the concepts of area and volume, they can use a calculator. In the real world, things are not measured in whole numbers; The dimensions are really messy and impenetrable to work with. When learning a concept, students should first work with simple numbers. They then move on to decimals and fractions where they find examples of real measurements. In the learning area, children will have to put in quite a bit of work, and solving problems will require them to make quick and accurate calculations. A calculator can help with this, and students will look for the value of decimals and significant numbers as they learn.

Calculators can take the guesswork out of it

In measurement problems where the distances are incorrect, a calculator can help provide the answers, but how does the student know they are correct? This is an opportunity to assess skills. If a rectangular board measures 12.67 by 3.14 inches and you need to find its area, how do you know that your answer can't be the number that appears on the calculator: 72.345? Estimate the dimensions by rounding to the nearest 13" x 3" and note that your answer should be slightly larger than a 39" square. Using a calculator is a great way to first guess your answer and then improve your math skills.

Using a calculator at work

In the classroom or alone at home, math students often wonder how their current unit of study will apply to their real world. Allowing them to use the calculator properly in math class will give them an appreciation for the great tool. Calculators speed up the problem-solving process, but they cannot think for themselves. It is as accurate as a person whose fingers pressed the keys and did the right thing. If designed correctly, using a Scientific Calculator in school will teach children the real-world skills of using the right tool for the job. When working for a boss or in their own business, students will have to accurately analyze the situation, determine a problem-solving strategy, use appropriate tools, develop a method for checking answers, and communicate clearly. The result. Portable calculators, computer applications or software will be an integral part of this process. Classroom experience with calculators will help students feel comfortable and efficient with this powerful learning tool.

Like any other tool, calculators are just machines that can be abused. But if students are taught how to use them in ways that enhance future success, these technological tools will no longer serve as props. See if a math student can get a general idea of ​​a concept or say the order of solving a problem by guessing the answer. They can then use a calculator to do some number crunching or try different results. A good teacher can then expect students to be able to justify their results. The calculator is an integral part of this learning and thinking process.
