Key Skills for 1st Grade
- ✓ Addition facts within 20 (all sums 1+1 through 9+9)
- ✓ Subtraction facts within 20 (inverse of addition facts)
- ✓ Sums greater than 9 (e.g., 7 + 8 = 15)
- ✓ Understanding that addition and subtraction are related
Learning Strategies
Count On
Start from the larger number and count up. For 3 + 7: start at 7 and count three more → 8, 9, 10.
Make Ten
For 8 + 5: take 2 from 5 to make 8 + 2 = 10, then add the remaining 3 → 13.
Use Doubles
Memorize doubles (6+6=12), then use them to solve near-doubles (6+7=13 is just one more).
Frequently Asked Questions
What math do 1st graders learn?
First graders focus on addition and subtraction within 20. Key skills include mastering all single-digit addition and subtraction facts, understanding place value for two-digit numbers up to 120, and beginning to add and subtract multiples of 10. By the end of 1st grade, students should be able to quickly recall sums up to 10.
How many addition facts should a 1st grader know?
By end of 1st grade, most curricula expect fluency with all addition facts within 10 (e.g., 3 + 4 = 7) and the ability to add within 20 using strategies. True memorized recall of all 81 single-digit facts is typically expected by end of 2nd grade.
What strategies help 1st graders with addition?
The three most effective strategies at this level are: Count On (start from the larger number and count up), Make Ten (break a number to reach 10, then add the rest), and Use Doubles (knowing 6+6=12 helps quickly solve 6+7=13). Short daily practice of 5–10 minutes builds fluency faster than weekly long sessions.
How can I help my 1st grader practice math at home?
Use this site for 5–10 minutes of daily fact practice. Focus on 1-digit addition first until they can answer confidently, then move to subtraction. Real-world practice also helps: counting change, measuring with a ruler, or adding points during games reinforces classroom learning.
