Instructions:

1. Use a compass to draw circles in your notebook. Each circle will represent a spinner.

2. Fill in the probabilities for each spinner as indicated below.

3. Colour each section according to the probability you choose, ensuring the proportions reflect the given probabilities.

Spinner Designs

1. The probability of spinning pink is 0.50.

   • Draw a circle and divide it to represent this probability.

2. The probability of spinning brown is 0.25.

   • Draw another circle and divide it accordingly.

3. The probability of spinning purple is 0.75.

   • Draw a circle and illustrate this probability.

4. The probability of spinning black is 0.60.

   • Create a spinner for this probability.

5. The probability of spinning blue is 0.80.

   • Draw a circle and represent this probability.

6. The probability of spinning green is 0.40.

   • Design a spinner for this probability.

7. The probability of spinning orange is 0.30.

   • Draw a circle and illustrate this spinner.

8. The probability of spinning red is 0.20.

   • Create a final spinner for this probability.

Reflection:
After completing your designs, discuss with a partner how the different probabilities affect the size of each section of your spinner.

• Look at the weather data for Hong Kong from April 23 to May 1. The data includes:

  • Dates

  • Temperature (in °C)

  • Weather conditions (e.g., sunny, cloudy, rainy)

  • Precipitation percentages

Instructions:

1. Create a Line Graph:

   • In your books, create a line graph

   • Plot the temperature on the vertical axis (y-axis) and the dates on the horizontal axis (x-axis).

   • Connect the points to show temperature changes over the week.

2. Optional: Precipitation Graph:

   • You can also create a bar graph to represent the precipitation percentages for each day.

Imagine you have a bag filled with:

• 8 red marbles

• 7 blue marbles

• 5 green marbles

If you reach into the bag without looking and pull out one marble, what do you think the chances are of picking a red marble?

• Find the Total:

  • Add up all the marbles to find the total number:

    • Total = 8 (red) + 7 (blue) + 5 (green) = ___

• Calculate the Probability:

  • To find the probability of picking a red marble, use this formula:

    • Probability of red = (Number of red marbles) ÷ (Total number of marbles)

  • Fill in the numbers you have:

    • Probability of red = 8 ÷ ___

• Explore Different Scenarios:

  • What if you added 3 more green marbles to the bag?

  • How would that change the total and the probability of picking a red marble?

  • Write down your calculations for this new scenario.
