Subtraction Facts - 3rd Grade Math

In third grade math, we have begun to focus more attention subtraction strategies.  One of the most commonly used and efficient strategies for solving basic subtraction facts is "think addition".  In this strategy, students might see the problem 15-8= and think 8 plus what equals 15.  In order for students to use this strategy they MUST know their basic addition facts.   Knowing the facts is defined as being able to orally answer within 2 seconds and answer in writing within 3 seconds.  We would typically expect students entering third grade to have mastered both addition and subtraction facts.  It is crucial that they have basic facts solidly in place in order to move on to more complex math. 

If your child is still struggling with fact knowledge, please spend a bit of time practicing at home.  If you need resources or suggestions on how to practice, please contact Mrs. Fitch or Mrs. Christy and we would be glad to help.
