Now that we are all struggling against the global pandemic, we are giving extra effort to cope up.  Even with our children’s education.

Good thing we are supported by the e-learning to make home schooling easy and possible.  Try to watch this video and get an idea.

Don’t forget to SUBSCRIBE. 

Thanks.

Leveraging Knowledge

An insight worth remembering from today's Math Review class: "If you don't know the answer to something, use what you know to figure out the answer."

Holla Math Lego

Prisms: LA = ph              

SA = ph + 2B              

V = Bh

Cylinders: LA = 2(pi)rh

SA = 2(pi)rh + 2(pi)r^2

V = (pi)r^2h

Pyramids: LA = 1/2pl       

SA = 1/2pl + B           

V = 1/3Bh

Cones: LA = (pi)rl

SA = (pi)rl +(pi)r^2

V = 1/3(pi)r^2h

Spheres: SA = 4(pi)r^2

V = 4/3(pi)r^3

Find lateral length with 45/45/90, 30/60/90

Guess what time it is? :D

MATH REVIEW TIME WOOOOOOH!

Quadrilaterals w/ perp. dia.- A = 1/2(d1)(d2)

Reg. Polygons - A = 1/2ap

Trapezoid - A = 1/2h(b1+b2)

Parallelogram - A = bh

Linear - a:b

Area - a^2:b^2

Circle - A = pi(r^2)

C = 2pi(r)

Sector of Circle - A = m/360[pi(r^2)]

Shaded part of sector = Area of sector - area of triangle

Multiples: 3/4/5, 5/12/13, 7/24/25, 8/15/17

Math Quiz Tmr Rant/Review

You'd think areas and perimeters would be easy, but nooooooooooooo. Math would find a way to fk that over too. Review (cause I know people who check Tumblr in the morning cough rainbowwafflez):

Parallelogram: A=bh

Trapezoid A=1/2h(b1+b2)

Quadrilaterals w/ Perp. Diag. A=1/2(d1)(d2)

Reg. Polygons A=1/2ap

Hexagons - make 30/60/90

Pentagons (are bchs) - tan/sin/cos

Keep in roots, no decimals unless specified

Apothem - bisect side, make right angles

(remember old stuff) 30/60/90 - x/x root 3/ 2x

45/45/90 - x/x/x root 2

Multiples: 3/4/5, 5/12/13, 7/24/25, 8/15/17
