Learning Targets
I can use equivalent ratios to describe scaled copies of shapes.
I know that two recipes will taste the same if the ingredients are in equivalent ratios.
I can compare rational numbers.
I can use rational numbers to describe temperature and elevation.
Right now in math we are learing about negative numbers and how to multiply and divide with them. We are learning with examples like the temperature outside. I think that negative numbers are usfull for the future. I think this because negative numbers are used in money if you have debt. It can also be useful with buildings. For example, say you have an elevator that goes underground then the floors would be going into the negatives.
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. This was a subject was that we did earlier in the year but I wanted to put it in because I believe that ratios are incredibly important for the future because you will need to compare things statistically for your whole life. I have grown in this subject because in the beginning of the year I had no idea how to compare things with ratios but now I use them a lot in almost all of my math problems.
