### Why You Should Use Calculators Regularly With Students

Using calculators in mathematics education offers several advantages, but it’s essential to strike a balance between calculator use and the development of fundamental math skills. Here are some benefits and reasons why students should be allowed to use calculators:

**Efficiency and Accuracy** – Calculators can perform complex calculations quickly and accurately, reducing the likelihood of arithmetic errors. This allows students to focus on understanding mathematical concepts rather than getting bogged down in tedious calculations.

**Complex Problem Solving** – In advanced mathematics and science, calculators are indispensable tools for solving equations, graphing functions, and performing statistical analysis. Allowing students to use calculators can help them tackle more advanced topics with ease.

**Real-World Application** – In the real world, people frequently use calculators and technology to solve math problems, making it practical and relevant to teach students how to use these tools effectively in preparation for their future careers.

**Focus on Conceptual Understanding** – When students have access to calculators, teachers can place more emphasis on teaching the underlying mathematical concepts, problem-solving strategies, and critical thinking skills. This shifts the focus away from basic arithmetic calculations.

**Inclusion and Accessibility** – Calculators can level the playing field for students with disabilities or those who struggle with manual calculations, enabling them to engage more fully in math education.

It’s important to remember that calculators should not replace the development of essential math skills such as mental math, estimation, and understanding number relationships. These skills are crucial for problem-solving and daily life. Over-reliance on calculators can hinder a student’s ability to grasp the underlying concepts of mathematics, which are essential for long-term learning and success.

Many standardized tests and exams limit or prohibit the use of calculators. Students who heavily rely on calculators may struggle in such situations. Proficiency in basic arithmetic is also vital for mental agility and mathematical fluency. Relying solely on calculators may lead to a lack of fluency in these essential skills and a decreased awareness of potential errors in one’s work.

### When Should You Use Calculators In The Classroom?

Using calculators in the learning process can significantly aid student development in a multitude of ways. They are particularly useful in solving complex mathematical and scientific problems, allowing students to focus on understanding the concepts rather than being bogged down by extensive calculations. This utility extends to checking work, where students can verify their manual calculations, learning from any mistakes and understanding where they may have gone wrong. In terms of real-world applications, calculators are indispensable in many careers such as engineering, finance, and technology, making their use in education vital for preparing students for the future.

Calculators can enhance the understanding of mathematical concepts by allowing students to explore patterns, comprehend algebraic principles, and visualize data, leading to a more profound grasp of these subjects. They also offer time efficiency, particularly in exam settings or time-constrained classroom environments, by enabling quicker problem-solving and allowing more time for the analysis and interpretation of results. This can be especially beneficial in providing equal opportunities for all students, including those who might struggle with basic arithmetic but have a strong conceptual understanding. By encouraging exploration and making learning more interactive and engaging, calculators can be a valuable tool in education. However, it is crucial to introduce calculators at an appropriate stage in education to ensure that they supplement rather than replace the development of fundamental arithmetic skills.
