That common core rubbish is messed up, so glad I did not need to learn that in school. I was bad enough at math as is without making it even more confusing lol.
IMO if they wanted to change the way they teach arithmetic, they should have used bit shifting, OR/AND/XOR etc gates to teach it. There would at very least be value in learning how math works at the digital level instead of some weird made up methods.
I don't know if you understand the common core mathematics. There is no weird made up arithmetic it's actually pretty basic. This is ripped directly from the website and it deals with first grade math which lets face it lays the basic foundation for any child. No where do I see "1+1 being 2 is racist" but feel free to look for yourself if you don't believe me.
Operations and Algebraic Thinking 1.OA
Represent and solve problems involving addition and subtraction.
1. Use addition and subtraction within 20 to solve word problems involving
situations of adding to, taking from, putting together, taking apart,
and comparing, with unknowns in all positions, e.g., by using objects,
drawings, and equations with a symbol for the unknown number to
represent the problem.
2. Solve word problems that call for addition of three whole numbers
whose sum is less than or equal to 20, e.g., by using objects, drawings,
and equations with a symbol for the unknown number to represent the
problem.
Understand and apply properties of operations and the relationship
between addition and subtraction.
3. Apply properties of operations as strategies to add and subtract.
Examples:
If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of
addition.) To add 2 + 6 + 4, the second two numbers can be added to make
a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
4. Understand subtraction as an unknown-addend problem. For example,
subtract 10 – 8 by finding the number that makes 10 when added to 8.
Add and subtract within 20.
5. Relate counting to addition and subtraction (e.g., by counting on 2 to
add 2).
6. Add and subtract within 20, demonstrating fluency for addition and
subtraction within 10. Use strategies such as counting on; making ten
(e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to
a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between
addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8
= 4); and creating equivalent but easier or known sums (e.g., adding 6 +
7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Work with addition and subtraction equations.
7. Understand the meaning of the equal sign, and determine if equations
involving addition and subtraction are true or false. For example, which
of the following equations are true and which are false? 6 = 6, 7 = 8 – 1,
5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
8. Determine the unknown whole number in an addition or subtraction
equation relating three whole numbers. For example, determine the
unknown number that makes the equation true in each of the equations 8 +
? = 11, 5 = � – 3, 6 + 6 = �.
