> 3 dayI had no idea the mastered tab would be such a motivator for my 6 year old! He enjoys mastering new facts and moving the cards to that section. The cards themselves are well made. I like that there is a diagran of each fact on the back and also that all facts are included (3+5 & 5+3 on separate cards, for example). A great set.

> 3 dayThese cards are wonderful, beautiful, well made, they come in awesome storage boxes, and I overall recommend them 100% However, I cannot give 5 stars because for some reason the developers thought you needed to have flash cards for multiplication by 0 (Really?! They all have the same answer!), multiplication by 1 (Honestly!! The answer is in the question!), and other groups of cards that are absolutely pointless to have. I would have preferred either getting more challenging cards, OR paid less to receive less product because I truly don’t want these cards that I have no purpose for. If the company fixes this, they’ll be 5 stars easily!!

> 3 dayI have tried different flash cards and these are hands down the best. There are three dividers within each box, which is motivating to get all cards in the mastered section. These cards kept my Son’s attention, which is usually 2 seconds. Of your child has ADHD or anxiety, I would try these.

> 3 dayI 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.

> 3 dayBecause 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.

Greater than one weekEasy to use. Thick cards (Not see through). My daughter struggled with math during our move in the middle of the year and with COVID. This has been a great daily tool over the summer to memorize her math facts. We only do it for about 10 minutes at a time in the morning and before bed. It’s not overwhelming and I really see a difference.

> 3 dayI’m very pleased with my purchase. I have been looking for these precise type of flash cards for a long while. The feel is great, they contain exactly the 0-12 for addition, 0 - 17 subtraction, 0-12 multiplication & 0-12 division that we needed. I’ve been trying to find something that my son and I can quiz each other on. I love that all number sections are color coded. It has a few tips for teaching and games that can be played. Dividers for what Is mastered, soft of know, and don’t know ! It also includes a full chart for each of the four boxes and the flash cards all have rounded corners. The small boxes that carry the flash cards is supper sturdy, easy to open and close. Even the box they come in fits perfectly in my drawer so they don’t get separated or lost.
