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).
