> 3 dayBest 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.

Greater than one weekThese worked WONDERS with my 2nd grader! Wish I bought them in kindergarten for her. It really has all the ones you need through 2nd grade (not sure what they do in 3rd grade since she’s not there yet.) her class has online tests everyday for 5 minutes and she went from 10-20 right to over 100, consistently, with these cards. I LOVE the section for “don’t know yet” — she has 3 seconds in school, so that’s what we give her at home. On the nights where you just don’t have time to do them all, this is FABULOUS!!! My only recommendation is keep them away from the kiddos so you don’t have to re-organize/find them, if they get ahold of them. EXCELLENT set of flash cards and totally worth it.

> 3 dayDurable finish and quality. 7 year olds use them to play War, having to know the answer to win the round. Turns out they do know their facts! On to multiplication/division for next year.

> 3 dayI love the visual aids along with the facts on the cards, the color coding, and the separators such as “needs work,” “got it,” etc. I’m very happy with this product and recommend for any age. I wish I purchased them in 1st grade.

Greater than one weekAddition cards. Nicer than anticipated. Big, easy to read. Color coded by numbers. Flash cards are of a decent quality sturdy card stock. I like the don’t know divider too.

> 3 dayOh, how I remember math flash cards as a kid myself. Now I ordered them for my granddaughter who will be starting school soon. Well, once the schools open again (presently sheltering in place). But in the meantime, she can start learning at home with mom helping out to prepare her for school. These subtraction flashcards are coated for more durability. There are dividers where theyre placed according to their skills such as: 1) Mastered 2) Dont Know Yet and 3) Sort of Know - which I think is awesome! Once your little one has mastered the beginning subtraction skills, then they can move up to a little harder ones, and so on. Learning can be fun!
