About Subtraction Facts to 20
What this skill is
Subtraction facts to 20 include facts with minuends up to 20 (like 15 - 8 = 7), requiring students to bridge through ten or use addition fact recall.
When children learn it
Practiced with mental strategies in 1st grade (CCSS 1.OA.C.6) and mastered for automatic recall from memory by the end of 2nd grade (CCSS 2.OA.B.2).
Teaching Tips
- Teach "Think Addition": for 14 - 9, ask your child "9 plus WHAT makes 14?". Since addition facts are usually remembered faster than subtraction, thinking addition makes solving teen subtraction twice as fast.
Common Mistakes
- Counting back on fingers more than three steps (like counting back 8 from 15), leading to frequent off-by-one errors.
- Struggling when minuends cross the ten barrier.
- Not realizing that knowing 8 + 7 = 15 instantly answers 15 - 8 = 7.
