Visual aids are great tools for teaching the addition rule in probability to Year 1 students! They help make hard ideas easier to understand.
The addition rule helps us find out the chance of either of two things happening.
For example, if we roll a die, we want to know the chance of rolling a 1 or a 2. We can write it like this:
This works if the two events can't happen at the same time.
Venn Diagrams: These are two circles that overlap. Each circle shows a different event. This picture makes it easier to see how different outcomes can combine.
Probability Trees: These look like trees with branches. They show all the different possible outcomes, which helps us see how we can add up chances.
Example: Imagine a bag with 2 red balls and 3 blue balls. We can use visuals to find the chance of picking a red or blue ball:
These visuals help us remember that when events can’t happen together, we can add the chances.
By using these aids, students can see and understand the addition rule in probability much better!
