Spring Progress Monitoring & Instructional Strategies for 1.OA.6
Spring Progress Monitoring & Instructional Strategies for 1.OA.6
Standard:
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). (1.0A.C.6) (DOK 1,2)
Progress Monitoring:
Ask to solve add/subtract problems within 10, i.e. 0 + 9 = 9, 9 - 4 = 5, 5 + 3 = 8. Note: If students use a counting strategy they are NOT fluent.
