Term 2 Reflection.
Hello, My name is Diana Rodrigues and I’m a grade 8 student. This term in math we did converting fractions, percentages, volumes, and surface areas. I did well on finding the surface area of different shapes. I found this chapters one of the easiest ones that we did so far. Also I did well on drawing nest and making 3D shapes on graph paper. The tests for Prisms and Cylinders weren’t even hard, I’d only get a couple wrong. Also I did pretty good on finding the volume of all those shapes. I really got how to do it, It easy to understand.
I wasn’t very good at remembering all the formulas for all the different shapes. Also I wasn’t very good with finding percentages and converting fractions. I often got confused. I kind of struggled on finding the volume of a shape inside of a shape, but after a while of doing it I kind of get it now.
For term 3 I’m going to try to get better in math by, doing more blogs, asking questions and finishing my homework. I want to be ready for grade 9 because I don’t want to fail. Try to finish all the questions that Mr.Harbeck assigns me, because they will help me understand it more and it will be easier for me on tests. I will also try not to rush on test, so I`ll read everything it is asking me to do. Also, I would like to do better on my blogs by doing more then Mr.Harbeck asked me to do, and try to comment on everyithng that is published. So that’s how I would want to get better.
I will post my Audioboo when I get it to work on my computer.

Term 2 Reflection
Term 2 Reflection
In term 2, I believe I did good on the nets of three-dimensional objects, the volume of the cylinder(π.R.R.H [Pi-3.14 x radius x radius x height]), the surface area of a prism(A=LxW [area=length x width]), and the volume of the rectangular prism(LxWxH [length x width x height]).
What made me struggle was remembering all the formulas on the volumes but in the end I was able to remember the 3 formulas.
For next term, I will try to stay focus and try to catch up on any home work that I miss. Also, I will try to get my marks up and my grades higher. Lastly, I will try to ignore the distractions throughout the grades.
What I learned about percents is that I can combine and compare percents. Also, what I learned about the surface area is that the surface area is the sum of all the areas and that it determines the surface area and volume of three-dimensional objects. Lastly, the volume. The volume is measured in "cubic" units. The volume of a figure is the number of cubes needed to fill it completely, like blocks in a box.
The difference between the surface area and the volume is that the surface area would be measured in square inches. The area of a flat surface, like a desk top. The volume is the inside area, like inside a balloon. This would be measured in cubic inches (inches x inches x inches).
I will try to add an audioboo sooner or later
Term 2 reflection
What I did well on this term was volume, I found it very easy to understand and I did good on the tests. I did most of the homework that was given.
I struggled on some of the homework, because I was lazy at some points and sometimes didn’t understand things. I would like to to better next term by studying on the tests and doing the homework. I would also like to use my time effectively.
What I learned about percents were how to find the percent of a fraction and decimal. What I learned about surface area was base multiplied by height divided by two for a triangular prism. Length multiplied by width for rectangular prisms, and pie multiplied by radius squared for a cylinder. For volume, we took the same formulas but we multiply a height as well.

Term 2 Reflection
Hi, my name is Marie Domingo and I’m here to talk about my term 2 reflection. I did well on the percent unit because it was the easiest for me. The percent problems took me at least 2 minutes to finish each. I understood it so fast! Also, I perfected most of my tests and quizzes. One thing I struggled with at first were making nets for prisms and cylinders. Even if Mr. Harbeck taught us how to draw them, it still confused me. But by lots of practice, I was able to draw nets more quickly and accurately. Next term, I will try to ask more questions and further my answers. Also, I want to perfect all my tests and quizzes.
In term 2, we learned about getting the percent of numbers and how to solve percent word problems. One method I really liked was using t-charts. Also, we converted fractions, decimals, and percents. I didn’t understand how to convert them at first, but after a while I was able to get it.
Another unit we focused on was surface area. All 3D objects are measured in square units. We learned how to make nets of prisms and cylinders using grid paper. A net turns a 3D object into a 2D object. A rectangular prism has 6 faces, and each face is a rectangle. There is a front, side, and top view of each rectangular prism. A triangular prism has 5 faces. 3 of the faces are rectangles while 2 of them are triangles. A cylinder has 3 faces. 2 are circles, and one of them is a rectangle. As I said, the hardest for me was making the nets. It was difficult to transform a 3D object into a 2D object containing all sides. Though, I was able to understand it after doing a few more nets!
The last thing we learned in term 2 was volume. The volume of an object is how much space the object can take. The formula to find the volume is v = area of base x height. For a rectangular prism, you would have to multiply the length and width together to find the area of base. For a triangular prism, the formula would be base x height / 2 x height. The base of the triangular prism is a triangle, and it cannot be anything else. For a cylinder, the formula to find the volume would be v = pi r r h x height. I didn’t have any trouble with this unit. This one was pretty easy to understand.
The difference between surface area and volume is that surface area is the area of the prism or cylinder’s faces. Volume is the area of how much an object can take. Basically, surface area is the area of the outside, and volume is the area of the inside.
Term 2 Reflection
For term 2 we learned about percent,surface area and volume. For percent we learned about showing percents into hundred grids. At class, we also learned about finding a percent of a number. We also learned about combining percents like finding the total price of the shoes by multiplying the number to the percent. In surface area we learned about viewing 3 dimensional object like looking what's the top,front, and side view. In this chapter we learned how to do nets which is the 2 dimensional version of the 3D object when flat. After knowing how to make a net we now learned how to get the surface area of a rectangular prism,triangular prism, and cylinder. Surface Area is the number of square units need to cover a 3D object. In the volume chapter, we learned how to calculate the volume of 3D object which you multiply the area of base and height for rectangular prism,triangular prism,and cylinder. Lastly we learned about solving problems involving prisms and cylinders. Which is for example a cylinder is inside a rectangular prism. We can either add it or subtract it depending on the problem
I did well on getting the surface area and volume of prisms because they don't confuse me and the part that I struggle is getting the surface area of cylinders because getting the surface has too many stuff going.
To do better for the next term I will study more and understand the problems more and if I'm confuse I will ask my classmates or Mr. Harbeck.
The difference between volume and surface area is that surface area is finding the area of the seen surface while the volume gets how many squares fill up the 3D object.
Surface Area and Volume have in common is that they both get the area of the 3 dimensional object.

Although, I wasn’t very strong with finding percentages and converting fractions. I often got confused when we would be solving a problem or doing a test. I also struggled in finding the volume of a prism inside a prism, I would get confused when they would tell you to round the answer to the nearest centimetre when it gives you metres. But I got Mr. Harbeck to help me out on that.
For term 3, I will continue to do all my homework and finish my textbook pages Mr. Harbeck assigns me. Finishing those pages really helped me understand more and made it easier for me on tests because I got a lot of practice. I will also try not to be lazy to read everything on a test because sometimes I rush and would get my answers wrong. That was a mistake I learned from. Also, I would like to do better on my blogs by giving more than what’s expected and comment every time there is work published because i would usually procrastinate and then I’m left with a whole bunch of posts to comment on. So that’s how i would want to get better.
What i learned about findings surface areas and volumes is that following the formula is very important. Like for cylinders, the formula for finding the volume is first you have to find the radius from the given diameter and the formula for that is base x height / 2, then you multiply pi x r x r x h, that’s how you would find the volume of a cylinder. I learned how to reduce a price with a given percentage, how to find the total cost of an item including taxes, how to convert fractions and decimals, I’m not the best at that, I still get confused but that’s something I will have to practice. I also learned that the difference between volume and surface area, is that volume is a measurement of the space a 3D object takes up, while surface area is the area of a 2D object.
I'll add my audioboo when I get it to work on my computer!

I struggled in percents the most because I did not understand it, I also struggled in volume because I couldn't remember the formulas. In Term 3, I would like to work harder on assignments, and homework. I would like to focus and demonstrate that I am learn. I also would like to do all of my computer work, so I will do better this in this Term. In term 2 i slacked off a lot and was easily distracted, this term I would like to be reminded if I a , and focus in my work. Therefore, I would like to sit with my usual friends, because they have helped me and explain what I was doing wrong. I am more comfortable doing work and homework with my friends, because they are very helpful and demonstrate good role models for me.
I learned a lot this term about percents, surface area, and volume such as all the formulas that are involved. And how to use the formulas correctly, so i wont mess up.
Term 2 Reflection
In the next term, i will work harder and prepare for the exams. i will get my computer work done and also my math work so i understand and don’t slack off this term. The things that were hard for me was if the area was already on the problem, i wouldn’t understand what to do. Someone that helped me a lot for this year was Cameron, He helped me understand the formula better and it really made a difference.
In the beggining of term two, we were also learning about percent, it was my best subject since it was always out of a 100. It wasn’t hard for me because there was no formula to comprehend. We also learned about the surface area, (didn’t like). the surface area had to much formulas that made me confussed.
Term 2 Reflection
At one point when we were learning about the volumes and when it was put in to problems, it sort of confused me because I didn’t know excactly how to find the answers.
I think I could do better next term by always reading the questions twice, or until I understand what the question is asking me. Another thing I want to improve on is too check over my answer again because I could of missed a single thing in the formula or something messed up which could change my answer on my tests.
This term I learned a lot about percents, surface area, and volume such as all the formulas that was involved. And how to use them all in a correct way so you won’t mess it up. I also learned some ways of finding out how much cm or m an object is if needed by using those formulas.
I will add an audioboo later, I do not have an itouch or a microphone at home.

In this term I did very well in finding out the volume of shapes such as trianglular prisms and cylinders, it was easy for me because all you had to do was remember the formulas of each shape such as (π x r x r)x h .

I learn a lot about Percent, Total Surface Area, and Volume. I learned how to find and combine percents. I also learned how to know which stores have better deals and save more money. I got confused at times and made mistakes but I learned from them. For Total Surface Area, I learned how to draw nets for different prisms and cylinder. Plus, I learned how to find the total surface area by using variety of formula. At first I struggled so much on drawing the nets. However with the help of my friend, I learned how to draw them without any help. I also learned how to find volume of shapes.Though it’s quite confusing at first, with practice, I started to solve problems independently.
