Best math flash cards on the market!! The design, quality, and practicality are better than other brands. The back side of each card displays the answer, along with a visual breakdown that explains the answer in cubes/charts. Therefore, your child is not just memorizing the answer, but instead understanding the concept and method to reaching the answer. Other brands I’ve seen do no provide this visual breakdown, nor do they provide all variables for each fact/number. Also, the color coding and one rounded corner at the top of each card makes sorting easy. So glad I bought these cards for my kids!! So worth it! Customer service is great, too, but please keep in mind that they are a small business so give them up to 48 hours to respond. They will respond and they are so thoughtful and professional.

I love these flash cards, good quality and my kids (10 and 6) like them. We end up getting the whole set, addition, subtraction, multiplication and division.

I like that these cards dont have a separate problem on the backside. (Not sure when that became a thing?) I think they are a bit too pricey though.

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.

Bought and used these with my Grandkids -- a little bit of Carrot and Stick -- one half hour of math facts almost every time they visit and they get a few $$ for their effort -- the improvement in their math facts and skills is REMARKABLE! Great quality and feel -- they will last for generations -- nothing like the basics of learning the facts to help kids with their confidence and improve their skills.

Very comprehensive.

I felt when I purchased I was getting all flashcards, addition, subtraction, multiplication, division

Love how simple & clear these are!

I bought these for my grandson. As a retired math teacher I wish I had these flash cards back when I was teaching! They are so well thought out! I like that there is only one fact on each card and I love that there is a box with file tabs to organize the cards as to whether the student knows the fact, is still learning the fact, or has mastered it.

The cards are durable, easy to use, and just what my struggling 3rd graders need to help them master basic addition and subtraction facts. The dividers are great, too, and allow you to separate items mastered from items that need a little review to items that are not mastered at all. We have been highly pleased with all Think Tank Scholar products we have ordered.
