1.OA.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.b., 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 sknown sums )e.g., adding 6+7 by creating the known equivalend 6+6+1=12+1=13).

Here are my math fluency assessments I used each week along with their tracking worksheet. I also attached a math center that I used with flashcards where they sort the facts. I did not attach all of them but I can if you all want me too.
