Common Core is one of the heavily debated issues between liberals and conservatives. Common Core is new Obama led initiative being implemented in most school districts nationwide. It’s a centralized system, giving the power over all public school students and their data to Washington.
Besides the logistics that over reach into our children’s test scores, and all the data about that child, Common Core is curriculum that changes the way our children learn. The math portion is so confusing, it is so irrational, its everything that the definition of math is not.
A video of Common Core math went viral recently. It illustrates the problematic issues at the heart of Common Core. Common Core has been compared to Orwell’s “1984″.

Would it not be 3×3=9×3=27×3=81×3=243 ?
Were are these teachers teaching. I want to know and better yet who are they that teach like this. What school did they go to.?????
Look at the definition. Google “repeated addition” that is included in home school methods.
Why change what has worked for forever
It’s just plain stupid and makes no sense.
Methods come form textbooks. Repeated addition is included in Home schools. Grading is teacher policy. Testing and data collection od from No Child Left Behind. NONE of these are addressed by standards like CC.
The post doesn’t say that 5+5+5 doesn’t equal 15. Both statements are actually true, and I think telling the kid it is wrong is not helping him. Here is my explanation:
5×3=5+5+5=15 is a true statement if proven. The only reason why 5×3=3+3+3+3+3=15 is a more favorable answer is because of the convention (not law) that terms get distribute from left to right, meaning 5×3=(1+1+1+1+1)(1+1+1)=(1(1+1+1))+(1(1+1+1))+(1(1+1+1))+(1(1+1+1))+(1(1+1+1))=(1+1+1)+(1+1+1)+(1+1+1)+(1+1+1)+(1+1+1)=3+3+3+3+3=15. Since it was not asked to prove the statement, it is reasonable to assume that the axiom of transitivity holds, namely for all real numbers a,b and c, if a=b and b=c then a=c. making 5×3=3×5 by commutative property and 3×5=(1+1+1)(1+1+1+1+1)=(1(1+1+1+1+1))+(1(1+1+1+1+1))+(1(1+1+1+1+1))=(1+1+1+1+1)+(1+1+1+1+1)+(1+1+1+1+1)=5+5+5=15. This is why the kid was right and the teacher wrong.
The grading is teacher policy and not part of any standards. That 5×3=3+3+3+3+3 and not 5+5+5 is from the definition of repeated addition defining 1st number as number of groups and 2nd as group size. The lack of flexibility like the Commutative property is to avoid confusing youngsters. This method is not mentioned in CC standards.
The basic problem with Common Core is too many determined misinformed opinions and too few discussions to understand how standards work with textbooks, homework, testing and grading. The repeated addition method is number of groups times the group size. It is important to treat the problem consistently. The youngsters are not yet ready to understand the flexibility of the commutative property. but this is to be judged by the teacher. 5×3=3+3+3+3+3 is correct at this point to avoid confusing the child. The definition of the repeated addition method is not in Common Core so blaming it is wrong.
The data collection is part of NCLB to prevent discrimination to insure all children learn a decade before CC. Again CC is blamed improperly.
“Repeated Addition” is defined by home schools as “number of groups times group size”. 5×3=3+3+3+3+3. Children learn 5×3=5+5+5 later when ready.
You are ignoring the lesson “repeated addition”, a home school method.
Any religion in schools IS NOT from Comon Core.
I’ve heard this re Common Core “dumbing down the kids.” What else are they teaching.
