Probability

 This week we started on our probability topic. 

Yesterday we looked at two dice probability. First we drew up a table in your books before receiving our two dice. I was in a group of three. We then took turns throwing the dice. We had roll the dice a total of 100 times then figure out the frequency and the percentage of all the possible totals that you can get rolling two dice. 

Triangles and Angles

This week we have been looking at angles and triangles using geogebra. We had to follow a few instructions to create lines/shapes and measure the angles. Then we had to move them around and find a rule for all of them. We found out that vertically opposite angles are the same, and that the inter angles of a triangle always add up to 180o.

Into To Geogebra

In maths this week we learnt about a tool called Geogebra that we are using with our new topic geometry and angles. This week has been more about getting used to the tool and teaching ourselves how to use it than having someone show us how to use it. Here are a few designs I made.

Prisms

This term we are looking at measurement. This week we have been looking at prisms in particular. Yesterday we looked to how to work out the volume of different prisms, and what is the length of a prism. The formula is volume = cross-section x length. Length is the distance between one cross-section to another.

The Border Problem

This week we have started to look at algebra and what it is. To me algebra is subbing out numbers we don't know with letters or images to answer equations.

Our big problem of the week this week is the border problem. We where given a 10x10 square like the one below, we had to work out how many red squares there are without counting them all individually.

My strategy to work it out was to take a side length or row and ignore the corners for now. Times the number of squares in the side length without the corners by 4 then add the corners back onto that number to get your answer.

What Makes A Good Mathematician?

In my opinion a good mathematician is not necessarily someone who is fast at solving equations. Nor someone who get a right answer first try, but someone who does give up when they get something wrong. Someone who seeks to understand why an answer may be wrong.

Growing up it has been ingrained into us that you have to be fast to be any good at maths, that we have to get the answer right first time. While people say we don't have to be fast or get an answer right, we are told the opposite making it harder for people to get into maths and to enjoy it.
