Flashcards? When they need to learn the addition or multiplication tables.
This is not the best way to teach a young child. Young children learn through play and exploration - not drills and workbooks. Forcing a toddler or preschooler to have "lessons" is a sure fired way to ensure he hates school by 5th grade. Any "gains" you make now, any bragging rights you have at the playground will be gone long before 5th grade in any case.
I'd suggest you do a little research into how preschoolers learn best and the research that has been done about the harm of forcing academics on your child too hard, too fast, and in a non-age-appropriate way.
Then check out sites like www.LetterOfTheWeek.com and www.StarFall.com for good ideas on playing with and teaching your young child at the same time. There's more to life than ABCs and 123s.
Keep it fun... build a life long love of learning.
