Well first off, today, we started by coming into the class and chatting to the people that sit near us. We stood for O'Canada and sat back down. Class started with Mental Math, as usual. Remember, if you got something wrong, you should come back to the Blog and see where/how you got the question wrong. Everyone should be getting 9 or 10's!
After the Mental Math, Mr. Kuropatwa asked us if we liked working in groups or solo. With the awesome response he got, we were divided into groups and worked on many questions. We basically worked on Perimeter/Circumfrence and Area questions.
Right at the end of class, we quickly looked at the formulas for Surface Area and Volume.
Triangle: P = a+b+c
Rectangle: P = 2 (L+W)
Square: P = 4s
Circle: C = πd OR C = 2πr
Triangle: A = 0.5bh
Rectangle: A = LW
Square: A = s2
Circle: A = πr2
Trapezoid: A = 0.5(Base 1 + Base 2)h
Rectangular Solid: SA = 2WH+2LW+2LH
Sphere: SA = 4πr2
Cone: SA = πrs (Slanted Sides Only)
Cylinder: SA = 2πrh+2πr2
Pyramid: SA = Area of Base + Perimeter of Base x Slant Height
Rectangular Solid: V = LWH
Sphere: V = (4/3)πr3
Cylinder: V = πr2h
Pyramid: V = (1/3)b2h
Anyways, CHRISTMAS IS 7 DAYS AWAY! =D and The Next Scribe Will Be: Cait ;)
Merry Christmas and Happy New Year! =D
