# Subtract 7 from a Number

- 1st Grade MathFirst grade requires students to internalize subtraction facts involving 1 digit numbers. These facts are building blocks for subtraction of greater numbers using the standard algorithm. **Subtract 7 from a Number Worksheet** focuses on practicing subtracting 7 (minus 7) from numbers within 20.

### Common Core Alignment

**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.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).
