Transformations
Transformations
In my math the biggest thing we’ve learned is transformations. Transformations are certain movements that make a shape or a point move. There are 4 types of transformation. Number 1 is dilation where you can shrink or enlarge a shape this does not work on a point for obvious reasons, next is translation where you move the shape or point from one place to another, also there is rotation, where you would rotate a shape or point around a point, now for the last one there is reflection pretty self explanatory but you would move a shape or point over a line in an exact reflection.
Pocket sized school
Pocket sized school
We don't really do this but we help out sometimes. So we measure lengths and heights of the building with a cool laser measure finding out the everything about the outside of the school, and once we finish we will 3d print it, and I don’t know what we are going to do with it.
Angles
Angles
There are multiple different types, more than I thought. The first one is the supplementary angle, two angles add up to 180 degrees. The next angle is a vertical angle, two angles opposite of each other on the other side but are the same angle. Now for adjcent angles, this is just two angles right next two each other. The last one is the complementery angle, two angles that come together to make 90 degrees and probably a lot more.
Constant of Proportionality
The constant of proportionality was really easy to learn about. A question on a packet would be like if Jonny has 3 Kit Kats for every 2/3 Reese's how many Reese's would Jonny have if he had 15 Kit Kats. It was very boring to learn about. The actual constant of proportionality would be how to multiply it, it is hard to describe but I would divide the Kit Kats by 3 to get one and then I would divide the Reese's by 3 and that answer would by the constant of proportionality.
Percentages
Percentages
Percentages were fun to learn about. Some of the questions would be like Jonny buys a jacket for 87 dollars. He used his 70% off coupon, how much was the original price of the Jacket. To solve something like this I would divide 87 by 30 to get 1%. Then I would multiply it by 100 to get 100 percent and find the original price of the jacket.
Inequalities
Inequalities are hard to describe but it is shown in the picture above, like X<7 means that x is smaller than 7 meaning x can be anything from like 6.9 to -infinity, but if you do this X<7 where the little aligator is underlined it means X can be anything from 7 to -infinity, the underlined aligator means it includes the number, and it also works for the same way around like it is bigger.
