These are very well made easy to use great addition to my sons education.

We have purchased Think Tanks products before. We were very happy with their word flashcard sets and are still using them, so when we searched for cards for math, I was pleased to see that they had those too. As with the word cards, the bottom line value for us as busy parents is the high yield factor. I have found that I get a lot of results from small focused amounts of time, a few times a week. We purchased the addition, subtraction and multiplication sets. Our kids are 7 and 5. Outside of legos or comics, our son, 7, has literally no attention span. The structure of the cards with the separate tabs for Mastered, Sort of Know, and Dont Know made it very easy for him to see progress which was motivating. He can look at the box and see the Mastered section growing each time and its clear how much satisfaction it gives him. With the multiplication cards, we started with the zeros, gave him the simple rule, Every multiplied by zero is zero. Gets them all right. Then the ones: everything by 1 is the same. Gets them all right. Hes on an early winning streak, and then its easier to move onto the higher complexity with an early base of confidence and engagement. He already counts by 2s and 3s at school, so we start out with those sections of the multiplication table in sequence so he sees the connection with addition, and he gets another winning streak. Then mix it up. Gets some wrong, but some right, but its ok and he tries again. So hes also learning about the process of how how to learn, and work from mistakes. So overall, pleased with the product so far. And each time we run through a section of cards, its literally maybe 10 minutes at a time. Like during breakfast. Works for us. Other plusses: I like the sturdy construction of the box-and-cap packaging and the general attention to aesthetics with the helpful learning graphics. We have other flashcards that are packed like a deck of cards, and they literally look like they have been shredded by wild animals (I guess little kids qualify as that) and the cards constantly falling out. Thanks for another great product.

I use these flash cards for an advance 5 year old. I love the cards, but most importantly she loves the cards. She loves to look at the parts she’s mastered and the ones she kinda knows. She’s always eager to memorize more for the mastered section to get bigger. The eagerness of a child to learn is priceless! Keep that in mind if the price deters you from purchasing these cards. They are of great quality and will last a long time.

These cards are well made and feel quality, however, one of the charts that came with the set, the Division Chart, was completely off. Kinda bizarre considering the rest of the products are so well done.

Love the quality of the cards, the tips included in the card set are wonderful. I bought this set for my first grader to help improve their mental math skills. Would definitely recommend to others.

Nice, large, complete set.

Love them, very good quality

Because of all schooling being at home during the virus, we found that my granddaughter who is a first grader needed to know her addition and subtraction by the end of the year. I ordered the addition, and subtraction card sets. They are perfect! She loves that she can make a pile for the ones she has mastered, in process, and needs to know. The box is sturdy, and because they are color coded, each number set is easy to find. They also work on the finding ten process that the school uses . . . giving her that visual on the back.

Really good quality. Worth the price.

these arrived on time and are sturdy high quality cards. they make learning easy and my nephew wanted to keep playing.
