Where did all the age appropriate normal math problems go? When I went to school it was addition, subtraction, multiplication, and division. As you got older things got harder. When you went into Algebra, Geometry, Trigonometry (which I never took by the way) it got a little more complicated of course, but in elementary school it was about making sure you understood the basics. Not so much today, thanks to Common Core.
My son is working on a sheet with multiplication problems…simple right? Not so much. What would one do if they had 6 x 297? Well under normal circumstances you would
- Multiply 6×7 to get 42, carry the 4 over
- Multiply 9×6 to get 54, add 4 to make it 58, carry the 5
- Multiply 6×2 to get 12, add the 5 to make it 17
- Voila a total of 1782.
Even this girl, who did not pass math with flying colors, can do that.
Thanks to Common Core, I can get rid of everything I learned (at least during elementary ages) to add several extra steps and confuse the heck out of my kids and myself.
This is how Common Core wants you to do it (taken from my son’s 4th grade homework page)
6 x 297
6 x 297 = 6 x (300 + 3)
= (6×300) – (6×3)
The point of adding all the extra steps is???? What in the world happened to multiplying like normal? When they have 3 sets of numbers like 20 x 72 x 5…I give up. I guess that would be (18+2) x (70-2) x (3+2) but I am sure I am probably wrong.
While we are talking Common Core, check out the fun they are having at my friend Trisha’s daughters school…in her post here, you can see there are pretty strong comments from both sides about common core.
And while we are on the subject of math (not common core related), what in the world is this Lattice Multiplication crap…
Sometimes simple is better, in my opinion, at least in the case of math. My thoughts….go back to the normal AKA old school way of doing math! Maybe I need to go sit in classes with my kids so I can see how the teachers break it down!
Does your school have the Common Core math?? I say we all boycott Common Core
