This is a song that helps me remember how to find the area of a rectangle: To get the area of a rectangle All you have to do is multiply First of all you gotta measure base and height Then you multiply base times height And then you got the answer!!!

Area and Perimeter

For todays class we were reviewing about perimeter and area. To find the perimeter of a polygon you would have to measure all the sides and add them all up. To find the area of a polygon you would only have to measure the length and width, then you multiply lenghth times width. I know the difference between area and perimeter is, for perimeter you have to measure all the sides and add them up, but for area you would ONLY have to measure lenghth and the width and multiply them.

For todays math class we learned how to find the area of a triangle. To find the area you will have to multiply basexheight, but to measure the height of the triangle you will have to move the ruler to the middle of the triangle and measure it. So then you multiply it basexheight and there you have it the area of a triangle.

For todays class we learned how to find the area of a parallelogram. To find the area of it you have to multiply length by width but before that you have to cut a piece of triangle of that parellelogram so to cut the triangle you would have to cut it at the top left corner of the parellelogram and go all the way down vertically so it would look like the side of a rectangle a straight line or visualise in your head so then once you cut the piece of triangle at the top left corner of the parellelogram and then you move it to the opposite side of where you cut the piece of triangle then you measure the length and width and multiply them and then you will find the area.

For todays math we had to do this question which was,what is the missing measurement of this triangle? Well i had to add the missing number to make a perimeter of 16cm. I also had to find the answer and convert it into millimeters and centimeters. I had to convert 41mm to centimetres which would be 4.1cm and 5cm to 50mm. I had to find the missing number so i subtracted 16cm from 9cm and i got 7. So then i had got 7cm and 70mm.

For yesterdays post i had done the question wrong and today i will do the write way. The question that we had to work on was, which method do you prefer? Well i would prefer Owens method because i found it easier because it was fewer steps than Diana's and Domenico.

I would choose Diana's method because i found it easy some how because it said 2x length and 2x width that equalled 46m. So then it said that (2x16)+(2xwidth) then i multipled 16 by 2 which equalled to 32 and then subtracted 46 by 32 which equalled to 14 the width then i multiplied it by 2 which equalled to 28m then i added it up 28+32 which equalled to 60m the answer.

I have learned that finding the perimeter of polygons is pretty easy because all you have to do is measure each side and add them up. I have learned that you have to measure each side and then add them up to get the perimeter of the polygon.

Patterning

I found the patterning unit easy. I have learned that input and output t-charts, x and y axis. I have also learned graphing and ordered pairs. Finding the rules for sets were fun and some were easy and some were challenging. I had learned ALOT from this unit like x and y axis and sets that had 3 numbers where you had to find how the three numbers relate so each one would have to relate to the next number. I had known some things like the input and output from grade 5 but the grade 6 patterning had reviewed things which i had remembered again.
