Using multiplication to make equivalent ratios can be tough for Year 8 students.

First, the idea of ratios itself can be confusing. Many students find it hard to pick the right number to multiply by.

Difficulties:

• Understanding the Concept: Some students may not see that equivalent ratios show the same relationship.
• Choosing Multipliers: Figuring out the right number to multiply can be tricky, especially with bigger numbers.
• Calculation Mistakes: If students multiply incorrectly, they might get totally different ratios.

How to Solve These Problems:

• Practice: Doing regular exercises can help them understand better.
• Visual Tools: Diagrams or tables can make the idea clearer.
• Step-by-Step Help: Teaching students to break the process into smaller steps can help them get it right.

For example, let’s say we have the ratio 2:3. If we multiply both parts by 2, we get the equivalent ratio 4:6.

By using these strategies, students can feel more confident in creating equivalent ratios with multiplication.
