Probability

 

Task Description: For maths today, Team Tui learnt about probability and how to create graphs on Google spreadsheets. We took the information from the container filled with blocks, created two graphs, and found out the probability of picking each colour if our eyes were closed.

P(Event): Chances of that event / Total number of outcomes

Learning About Pi

Task Description: Yesterday in the morning for maths, we learnt about pi!  First, we had to measure the circumference using some string, then we measured the diameter using a ruler. We divided the circumference by the diameter on our chrome books and the result is called pi. The value of pi is just over 3.

Probability Games

Task Description:

Yesterday for maths, we did it in the assembly hall! We were playing probability games, probability is how likely something will happen. We were split into three groups so that there would be rotations for the games. Everyone also got a paper to record their success and their failure for each game.

The first game for the group I was in was greedy pig. Greedy pig is rolling a die and you get points for what number you rolled. However, if you roll a one, you have to restart from 0 points again. I think it was the most difficult game for me, I had to restart 4 times and I only got 39 points at the end before the rotation ended. If you got 50 points you could get a lolly but I only had 39.

The next rotations were playing cards and bottle flip. For the playing cards I aimed for no picture cards, and my success was 25 and the failure was 15. For bottle flip, my success was 6 and my failure was 30.

Measuring Angles With Protractors

Task Description: For maths, were are learning about how to measure angles with protractors! When you measure an angle, you have to put one ray at 0°. You also have to put the intersection of the rays inside the small circle on the protractor. In the image above the question is “Is this angle acute, right or obtuse?”. An Acute angle is a angle less than 90° while and Obtuse angle is a angle more than 90°. A Right angle is exactly 90°. The angle in the image is a 90 angle because 60 – 150 is 90. 👍
