how to find the area of a triangle and parallelogram

how do you find the area of the triangle?

first you measure the base of the triangle then you measure the hight of the triangle. then you multiply the base and the hight and then you divide the answer by two. you then have this number you don't know what to do with so just to tell you thats your new answer! all you have to do is add the cm2.


how to find the area a parallelogram?

first you measure the base and then you measure the hight and then you multiply them.So now you have this number then you divide it by two, then don't forget to write cm2. Also when you cut the parallelogram in half i turns into two triangles so when you measure the triangles they will still be the same base and hight and when you multiply the numbers usaully that answer and if you put that parallelgram on a graph paper example 24 is your answer then 242 squares would be able to fit into the parallelogram but if you cut in half the number would stay the same. there would be many less squares that would be able to fit into the triangle.

how to find the paralelligram

to find the perimeter i measure all the sides
2(L+W) and then you just multiply them all up
example...if you have a square and all the two sides are the same and the other two sides are exactly the same length then you measure the one side then you know that the other side is the same so then you mesure the other side and then you multiply them all up then you have your answer.

the missing measurment!!

we have to figure out what the missing measurement is.


41mm first you multiply 5cm by 10 (50), then you multiply 16cm by 10 (160),then you subtract 160 and 91 and you get 69 for the missing measurement.

the missing measurement is 69

5 cm

witch i perfer most?

well we had to decide wich way we perferd mostand i perfer Owens way most because...
he said... p=2(16+width) p=2(length+width)

i perfer that way more because it took way less time than the others and i didnt need to do a million steps to get the awnswer like i had to on the others.

reflection on the whole patterning unit

At first i really hated it and that was because i had no clue how to do it! but then i started to get the hang of it and i got really good at it! at first i thought the finding the patterns were the hardest and to this day i still do! i thought making the t-chart was the easiest to do because i just understood it most. but now i think it's kinda fun not really but kinda.!!!

my journal

i have learned that when you add all of the numbers up that you have to make sure that you dont forget to put the decimal and i learned that the hard way. i also learned that you can do them anyway like i thougt you could only do addition but you can do any kind of math to get the answer. also it's kinda hard!!
