Tips for Learning Addition/Subtraction Facts
Tips for Practicing the Facts
-
Group practice by strategy. This is a good order to go in.
Doubles: 1+1, 2+2, 3+3, 4+4, 5+5, 6+6, 7+7, 8+8 , 9+9
Near Doubles: If I know the doubles, then I know the facts that are one more or one less
Ex: If I know 3+3=6, then I know 2+3= 5 and 3+4=7
3+4, 4+5, 5+6, 6+7, 7+8, 8+9, 9+10
Facts that make 10: I should know all my combos of 10 quickly.
Add a ten: I should be able to add 10 quickly, without counting on by 1’s
1+10, 2+10, 3+10, 4+10, 5+10, 6+10, 7+10, 8+10, 9+10
Once I can do this, practice with higher numbers (21+10 etc.)
Adding 9: If I can add a 10 quickly, then I can add 9 by adding 10 and then subtracting 1.
Ex. 7+9 …. Think 7+10 is 17, subtract one and I have 16.
Bridging to 10: I can break one of my numbers apart to make a 10, then add on the rest. This strategy only works if I know my combos of 10 really well!
Ex. 8+5. I know that 8+2 is 10, so I’ll take 2 from the 5 to make a ten. I still have 3 more to add from the 5, so my answer is 13.
Ex. 7+4, 7+5, 8+4, 8+5, etc.

Practice addition and subtraction facts together, again focusing on strategies.
3. Keep track of “Facts I Know” and “Facts I’m Learning” Introduce only a few new facts at a time. Over time, the “Facts I Know “ pile will grow!

Math Facts are best learned and practiced by utilizing strategies. Consistent practice of 5-10 minutes a night will help your child master the addition and subtraction facts. Fluency with math facts is critical to success!! Please make the time to practice!
