Understanding BODMAS/BIDMAS for Year 8 Students
Learning BODMAS/BIDMAS can feel pretty tough for Year 8 students, especially when they start working with algebra. BODMAS stands for Brackets, Orders (like powers and square roots), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).
This set of rules can sometimes confuse students, leading to mistakes and misunderstandings in math.
Misreading the Math Problems: One big problem is when students don’t read expressions correctly. When there are many operations in one problem, it can change the answer a lot. For example, in the problem (3 + 6 \times (5 + 4)), if a student just goes left to right, they might get the answer wrong: [ 3 + 6 = 9 ] [ 9 \times 5 = 45 ] But if they follow BODMAS, they should first solve inside the brackets: [ 5 + 4 = 9 ] Then, it becomes: [ 3 + 6 \times 9 = 3 + 54 = 57 ]
Too Much Trust in Basic Skills: Sometimes, students feel too confident about their basic math skills—addition, subtraction, multiplication, and division. They might think they can do any problem without following the order of operations. This can lead to mistakes and a misunderstanding of algebraic rules.
Ignoring Brackets: Students often miss how important brackets are. Brackets tell us which calculations to do first. For example, in the expression (4 \times (2 + 3)^2), if they skip solving ((2 + 3)) first, they might end up with the wrong answer: [ 4 \times 2 + 3 = 8 + 3 = 11 ] Instead, they should do: [ 4 \times 25 = 100 ]
If students don’t follow the order of operations, they can make big mistakes in math. These small errors can lead to even more mistakes in future math topics, which can hurt their confidence and grades.
The good news is that these problems can be fixed. With some practice and the right tips, students can learn how to handle BODMAS/BIDMAS better!
Follow a Simple Step-by-Step Approach: Here’s an easy way for students to work through problems:
Use Visual Tools: Many students find it helpful to see things visually. You can use flowcharts or colorful charts to show the order of operations. This helps students remember the steps better.
Practice, Practice, Practice: Practicing regularly is key. By working on lots of different problems—both easy and hard—students can get comfortable with BODMAS/BIDMAS.
Work with Friends: Collaborating with classmates on math problems can be really helpful. Talking about mistakes in a friendly way lets students learn from each other.
While learning BODMAS/BIDMAS can be tricky for Year 8 students, it isn’t impossible. With practice and a little help, students can get better at this. By understanding where they often go wrong and working to fix it, they can not only make sense of their algebra but also create a strong base for future math success.
