Visual aids are really helpful for understanding ratios in Year 11 Mathematics. They make tricky ideas much clearer. Here are some important reasons to use visual aids:

1. Clarity:
   Diagrams and charts, like pie charts or bar graphs, show how different parts relate to each other. This helps students see how ratios compare easily.

2. Representation:

   • Part-to-Part Ratios: These show the connection between two groups. For example, in a class with a ratio of boys to girls like $3:2$, you can easily see how many boys there are compared to girls.
   • Part-to-Whole Ratios: These show how one part fits into the whole picture. For instance, a $3:5$ ratio means there are $3$ parts from a total of $8$ parts.

3. Engagement:
   Research shows that students remember $60\%$ more when they use visual aids instead of just listening or reading.

By using visual tools, we can turn confusing numbers into something we can really understand. This makes it easier to see how these ratios work in everyday life.
