This is a great product for kids struggling with subtraction. My son has trouble with the timed tests. We have seen improvement since we began using the flashcards. --Amazon Wow, I'm impressed with the results. My grand son is going into Kindergarten this Fall and wants to learn his math but hard to keep him involved for long. With these he will go through the entire deck, almost like a game, before 'finishing his homework' and losing interest. Amazing results make it well worth it, cannot beat the price, and they are study and will hold up for his use and that of his younger sister I am sure. Definitely recommend them. --Amazon These subtraction flash cards are excellent flash cards. Do not think, for a moment, that these particular flash cards are not effective.

Visionary in business, she has long looked at the world through a child’s eyes, infusing her stories and lessons with joy and relatability.
