Make numbers a part of your everyday routine. Your child might not like addition, but he may enjoy counting the number of stop signs on the drive to school or the number of stairs on your porch. Lead by example to encourage your child to think of math exercises as a part of his daily routine.
For kids that have a basic interest in math, try using daily riddles to keep them thinking throughout the day. At breakfast, you may ask your child a riddle like, "What number has three tens and four ones?" or, "What is a mathematician's favorite dessert?" Your child can take the day to think about the riddle and tell you the answer when you're working on math practice worksheets after school!
