I understand how to use percentages is many ways. I can convert between percentages and decimals and I can model percentages on both a double number line and also a tape diagram. I also know how to calculate percent increases and decreases and how to calculate simple interest.
The new information I have is that I now have learned more about percentages. I learned more about models than I used to know. I practiced using percentages in math more and made my brain bigger.
The interesting things about the unit is how you can split numbers with percentages and it is a way to show fractions and decimals. It is interesting to see how percentages and these model things work.
The things that were tricky for me was sometimes doing modeling and stuff and showing my work but then I learned it and now it has become untricky.
