Interactive tools might look helpful for teaching how to convert units, but they can actually make learning harder for Year 9 students.

Here are some challenges:

1. Too Much Stimulation: Students can feel overwhelmed by too many interactive features. This can cause more confusion instead of helping them understand better.

2. Technical Problems: Relying on technology can lead to frustration when there are connectivity issues or software glitches.

3. Lack of Interest: Not every student enjoys interactive formats. Some might feel bored or disengaged.

Here are some possible solutions:

• Provide clear instructions along with these tools.
• Mix technology with traditional teaching methods to support learning.
