Relate the numbers and multiplication tables to everyday life. Try to find ways to incorporate the math tables into daily life. This will help you truly understand the numbers instead of simply memorizing the material. If you know that a special holiday is only 8 weeks away, you can use your multiplication facts to figure out how many days away it is. There are 7 days in a week, so 7 times 8 is 56. Your holiday is only 56 days away!
