My poem/wrap about area

Each person in our class had to write a poem/wrap about area and/or perimeter. I chose area so I hope you like it.

To find the area of a triangle, all you have to do is........go base times height ya that's really all you have to do but wait........there's more........then you have to divide it, ya you got it, divide it, because........a triangle is half........half of what? a rectangle........you got it half of a rectangle........then what? well that's all you see.

Area and Perimeter

This is the difference between area and perimeter. Well area, you have to do base times height, or length times height. Another way to do it is if you have graph paper. If you have graph paper, you would have to find all of the whole squares add them up, and then add put the smaller pieces together which would make a whole square. There is also I more thing that you have to remember. You have to remember to put cm2. The 2 is for squared. Now for perimeter. Perimeter is the distance around the shape or object. So all you have to do is add up all of the sides. I don't have any tricks or ways that help me so to bad.

How to find the area of a triangle

Here is how you find the area of a triangle. Well it's a little bit harder then a square so you'll have to listen closely. Just pretend you have a rectangle( or a parallelogram) that is 9 for the height, and 4 for the base. Then if you split it in half, it will become a triangle. But then the triangle and the rectangle( or parallelogram) will be the same area even though they are not the same area. So for finding the area of a triangle, you will multiply the two sides together, and split it in half. If the two sides of the triangle are 9 and 4, the answer would be 36, but you have to divide it by two, so the answer is 18cm squared.

How to find the area of a parallelogram

In class today, we learned how to measure a parallelogram; well this is how you do it. There are two ways how to find area. One is to do height times base, or length times width. Another one is to find all of the full squares, and then find the halfs or other small pieces and add them up to make a couple more full squares. A parallelogram is a pretty easy shape to find the area, so lets get started. If you have graph paper, that will be easy because you can see the squares. But if you don't have graph paper, you'll have to use a ruler. That's all there is to it! Have fun trying it!

Perimeter Question #2

A problem that we had in math class today is : The perimeter of a triangle is 16cm. What is the missing measurement? The triangle had 5cm on one side, 41mm on another, and the last side was blank. Well first of all, you have to make sure all of the sides are in one unit of measurement. One side is in cm, and the other in mm. In the question, it said that the perimeter of the triangle is 16cm, so let's change it to cm. If you had 41mm, you would have to move the decimal over to the left one space. So now it is 4.1cm. Then you will have to add 5cm and 4.1cm together which is 9.1cm. Now if you know the triangle is 16cm, you just have to subtract 16cm and 9.1cm. The answer is 11.9. So there you have it!

Perimeter Question #1

In math today, our question we had to answer, on here was : Which method do you prefer? Explain why. There were a couple of different ways people answered them. I think the easiest way for me was, P= ( 2 times length) + ( 2 times width) 46 = ( 2 times 16) + ( 2 times width). I think this was the easiest way for me because I have always done it this way in math. I also do it because it is faster than adding up every side. In this strategy , you just have to go 16 times 2, and 7 times 2. Instead of going 16 + 7 + 16 + 7 = 46.

My Journal

Today in our homework assignment, we had My Journal at the bottom of the page. The question was: What have you learned about finding the perimeters of polygons? I have learned that if all of the sides of a polygon are the same, you can go one side of the polygon times another side, and get the answer. So an example of this would be 4cm times 4cm = 16cm. I also learned that if you have a triangle, and each side is 2cm, you wouldn't have to add up 2+2+2=6. You could just go three times two. The three for the three sides of a triangle, and two for all of the equal sides of the triangle. So I think it is good to know your multiplication skills and the # of sides on shapes. So I didn't learn a lot today because I had already known all of this stuff.
