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. 👍

IXL Measurements

Task Description:

For maths, we learnt about measurement! We’re learning how to be confident when measuring things. We did this on IXL, you had to drag the ruler and measure objects. When you want to measure something, you must have one end on the 0 cm mark, then you can properly measure it. After you measured it, our teacher also told us to convert it to millimetres. The swordfish in the image is 19 centimetres, but when you convert it to millimetres its 190 millimetres.

Finding Perimeter of a Shape

Task Description:

For maths, our task was to go into groups of 3 and choose one from the measurement equipment pile.  I was in a group with Phyu sin and Stephanie.Then, we could have fun with the equipment for 5 min! After that, you had to make a shape and find it’s perimeter. Because the sides of our shape were curved, we had to use a flax and curve it over the shape and then measure how many centimetres the flax was. After we found the perimeter we had to convert it to millimetres, centimetres, and meters.

The perimeter of our shape was 84 cm. So, 84 cm, 840 mm and 0.84 m.

 

Circle Geometry Maths

Task Description: For maths, we were learning how to use a compass!

First, you had to practice with the compass in your maths book and then draw and label the centre, the diameter, the radius and the sector. Once you were done with that, you got a paper and drew a circle with a flower in the middle using the compass. Then you made an even bigger flower like the one in the picture! You were able to colour it however you liked.

 

Pentominoes

Task Description:

For maths, we learnt about pentominoes! First, we had to find & draw the 12 pentominoes in our maths books , it was really challenging. The rule was it had to be connected but not by the corners. After that, we got printed papers with pentominoes on them. We had to cut them out and do challenges. For the first challenge it was a 3×5 square with the pentominoes. The second challenge was a 4×5 square, and the third challenge was 5×5 square.  For the last one, I believe the 4th or 5th challenge was a 3×10 square?
