How to Remember Area Formulas
Remembering area formulas can be a challenging task, especially for students who are new to geometry. However, with the right techniques and strategies, it is possible to memorize these formulas efficiently. In this article, we will discuss various methods to help you remember area formulas with ease.
1. Visualize the Shapes
One of the best ways to remember area formulas is to visualize the shapes for which the formulas are applicable. By understanding the shape’s characteristics and how it is divided, you can easily recall the formula. For instance, consider a rectangle. It has two pairs of equal sides and four right angles. The area of a rectangle is calculated by multiplying its length and width, which can be easily remembered as “length times width” or “l x w.”
2. Use Mnemonics
Mnemonics are memory aids that help you remember information by associating it with something more memorable. For example, to remember the formula for the area of a triangle, you can use the mnemonic “base times height, divided by two” or “b x h / 2.” This association will make it easier to recall the formula when needed.
3. Create a Formula Chart
Another effective method is to create a formula chart that lists all the area formulas and their corresponding shapes. Include the formula, the shape it represents, and a brief explanation. This chart can be kept in a visible spot, such as on your desk or fridge, so you can refer to it whenever you need to recall a formula.
4. Practice with Examples
To reinforce your memory of area formulas, practice solving problems that involve these formulas. Try to solve them without looking at the formula chart or your notes. This will help you develop a deeper understanding of the formulas and improve your ability to recall them.
5. Use Acronyms
Acronyms can be a powerful tool for memorizing area formulas. For example, the acronym “CUBES” can help you remember the formulas for the area of a cube, cylinder, sphere, and rectangular prism. The letters in “CUBES” correspond to the first letter of each shape’s name: cube, cylinder, sphere, and rectangular prism.
6. Teach Others
Teaching the area formulas to someone else can be an excellent way to reinforce your own knowledge. By explaining the formulas and their applications, you will gain a better understanding of the concepts and be more likely to remember them.
In conclusion, remembering area formulas can be made easier by visualizing the shapes, using mnemonics, creating a formula chart, practicing with examples, using acronyms, and teaching others. By incorporating these techniques into your study routine, you will find it much simpler to recall area formulas when needed.
