Tree diagrams can make probability questions tricky for Year 7 students if not used the right way.

Challenges:

• Tree diagrams can look very busy and confusing.
• It’s easy to mix up the branches, which may lead to wrong answers, like adding probabilities when you should be multiplying them.

Ways to Help:

• Start with easier examples. This way, students can learn the basic ideas first.
• Talk about how many possible outcomes there are and make sure to label the branches correctly.

With some help, tree diagrams can become a useful tool. They can make it easier to understand how different outcomes relate to each other in probability.
