Using real-life examples is a great way to help Year 7 students learn about fractions and percentages, especially when it comes to probability. When we connect these ideas to things they see every day, it can make understanding probability a lot easier.

Understanding Fractions and Probabilities: Let’s think about a bag with different colored marbles. Imagine there are 5 red marbles, 3 blue marbles, and 2 green marbles. To find out the chance of picking a red marble, we first add up all the marbles.

So, we have: 5 (red) + 3 (blue) + 2 (green) = 10 marbles in total.

Now, the chance (probability) of picking a red marble is:

$P(\text{red}) = \frac{5}{10} = \frac{1}{2}.$

This means that you have a 50% chance of picking a red marble, which we find by turning the fraction into a percentage. We do that by multiplying by 100.

Relevant Situations with Percentages: Another easy example is asking a class survey about favorite sports. If 12 out of 20 students say they like soccer, we can show that with a fraction like this:

$P(\text{soccer}) = \frac{12}{20}.$

To change this into a percentage, we do the calculation:

$\frac{12}{20} \times 100 = 60\%.$

This tells us that 60% of the students prefer soccer.

Real-Life Applications: We can also use real-life situations like weather forecasts to make learning more fun. If the weather report says there is a 40% chance of rain, students can see this as the fraction $\frac{40}{100}$. This means there’s a 2 out of 5 chance it will rain.

In summary, by using examples that students are familiar with, they can easily grasp how fractions, percentages, and probability work together in math. This method not only makes learning more exciting but also helps build important math skills that they will need, especially in the Swedish curriculum.
