We were asked to think about the different types of comparison statements we’ve been writing and our work with rates and unit rates. In this video I’ve addressed 2 questions: 1) HOW have you found these ideas helpful. 2) Make up an example comparing two items using unit rates.

Figures are mathematically similar.

You can find that their shapes are similar by finding ratios, scale factor, or true proportion. For example if there are two line segments on the bottom of the triangle you would divide those two segments to find scale factor. You can find true proportion by using ratios with the ratios you cross multiply and each number you get should be the same as the other number you get by multiplying. You can find how shapes are similar with ratios by simplifying them and seeing if they are factors.

True or False

Any two Rectangles are similar. This is false because the line segments could be different lengths, for example a 4 by 7 rectangle can not o into a 8 by 15 rectangle.

Any two equilateral triangles are similar. This is true because equilateral triangles have similar side lengths which make similar angles.

On the front side of the assignment we had to find which shapes were similar. We also had to show how we knew. I solved this problem by finding the scale factor between each shape.

For the back side we had to make shapes that were similar to the rectangle but not congruent and draw a rectangle not similar. We also had to draw a figure similar to the triangle but not congruent. And we had to draw a triangle that was not similar. For the questions were it said draw a shape similar but not congruent I just made a shape twice the size. I made it twice the size because if it is twice the size it is not congruent because it is not the exact same but it is still similar. It is not congruent because it is not the exact same shape. For the shapes that were not similar I just drew a shape that the side lengths were not related at all.

The photo on the left is the better notes of the two because it is it very organized, spread out, and it has a drawing that is visible and clear.

The Next Photo is not great notes. I think it is bad notes because it is not spaced out, not clear, messy and it has a couple of doodles on it.

Last year was hard but rewarding. I feel like last year we covered so much. In fourth grade I remember math was so easy but middle school is a whole new beast. I like learning math because whenever you learn how to do a unit it feels so rewarding. It also helps you when you’re outside of school. I dislike that it makes me stressed. The time I get stressed most is when I am doing homework and it’s late and I am stuck on a problem. Also I dislike it when I feel behind in math. I usually feel behind because I am not very fast with math or I’m not very focused. I think I am not the best at math but I am ready to excel. My routine when I study is to first, look at the type of problem and do the easiest problems and then, work up to the hardest problems. If I get stuck, the first thing I do is check over the problem for careless mistakes then, if their are no careless mistakes, I will do the problem over. If I get stressed out I can take a break, or work on something else, or just read and come back to the problem. I am excited for this year and I will try my hardest in everything we do.  

26]     40 = 20% of what number?

40 = 20% x

.2/40=200

Story Problem:  I have 40 baseballs which is 20% of the amount of baseballs there are on the  field. How many baseballs are there.

27]     8 1/2 of 500.00=

.085 x 500=

.085 x 500 = 42.50

Story Problem: I have 500  bags of goldfish my dog ate 8 1/2% of the bags of my goldfish. How much is 8 1/2% of the goldfish bags.

28] 18=  _____% of 150

18=_____% x 150

18=12% x 150

Story problem: I have 150 packs of gatorade my dog drank 18 bottles of it what percent is 18 bottles of 150.

         The picture in the top left is of a page in my math test. On that page I got four problems right and two wrong but on the test I only got two’s and one 2.5. The picture on  the top right is a pop quiz were I got two right and I did not simplify one. The picture on the bottom is my scores from Extra Math.

My way of doing division is taking the biggest chunk out of the number.

This is not finished because some times My work can go a little slow. Another reason I did not get this done is that my tessellation went a little longer then expected.

This is my tessellation. This is special because I worked really hard to make it perfect. This has to do with math because you have to fit all the angles together.
