Practicing Math Facts
In order for your child to have success with more advanced math, it is essential that they memorize their basic facts to the level of automaticity.  This can be achieved through skill and drill repetition as well as some more creative methods.  It may come quickly for your child, or it may take time, but through focused practice, they will be able to increase their proficiency.
Your child is introduced to basic math concepts such as counting and adding using representative objects in kindergarten.  S/he must all master addition and subtraction facts through 5.  Through first and second grade they will have extensive practice with adding and subtracting one digit whole numbers along with learning many other skills and concepts.
Understand addition/subtraction fact families. Fact families are groups of three numbers that are related to one another.  4 + 3 = 7, 7 – 3 = 4, and 7 – 4 = 3 therefore the numbers 4, 3, and 7 have a relationship to one another and are considered a fact family. 
Create or purchase flash cards. You can make flashcards from index cards or cardstock paper.  Write each of the fact on the card.  Start with +0, +1 and move from there.  Use the cards to play games to make facts more exciting.
