Our SmartKidsPlanet initiative began in 2017 when 3 geeky and dedicated parents saw a gap in the children’s toys and games market. An opportunity was spotted while we struggled to find toys and games for our kids which enriched their minds and guided them toward science, art, math and construction. The trio then knew that their paths were set, establishing an online shop with a comprehensive range of intelligent toys for babies, children and young teenagers.

With offices based in California, our SmartKidsPlanet team enjoys a daily growth in our presence within the children’s educational toys market. We love our new place in life, and we love helping young minds with their growth and skill development, all while having as much fun as possible.

Meets expectations

So I read a lot of reviews on cards before I bought these. Just got them. They are cards. Have problems on one side. Solutions on the other. Well, that is what I expected of flash cards. I think there are a lot of picky reviewers out here. I might like a different box. I might like them laminated. But they are flash cards. I have one daughter. I only need these for a year.I recommend these. I bought subtraction and multiplication also.

An actual full set.

One of the only sets that actually includes every addition fact. Which helps tremendously with creating sets for review.

It All Adds Up!

These are great flash cards! They are thick and complete, easy to drill, and just the right size to turn as well as to see with ease. Just add an online stopwatch from the internet and you have a nice summer review session for 2nd and 3rd graders!

Kassidy Wilkinson
The best math flashcard design!

These are the best flashcards for math learners, simply because they have just one problem per card, rather than one problem on the front and another on the back. Two-problem cards are very confusing to sort in correct/incorrect piles, for one. One-problem cards are better because the learner can see the entire problem on the answer side, reinforcing the facts visually as they learn. I recommend all flashcards from this company!

Perfect for my 1st grader

After spending time reading reviews I decided to order this set. I am so happy that I did. These are used for my 1st grader who is a very visual learner. I love that these show the entire problem PLUS the answer on the backside. He enjoys them.
