Trend Enterprises: Three-Corner Multiplication and Division Flash Cards, Interactive Self-Checking Cards, Exciting Way for Everyone to Learn, 48 Two-Sided Cards Included, Ages 8 and Up

This is a great way for kids to learn multiplication and division facts. Depending on which corner you cover to divide or multiply. I've also used the addition and subtraction cards with first graders. Great way to learn about fact families.

Bought these at the recommendation of a math specialist to reiterate multiplication and division facts. I love these cards because they provide so much variety. I keep these in my purse and use them as flash cards throughout the day. In order to increase the chances for rote memorization, I shuffle the cards and pull them out at random. Very very good concept.

We love these! So easy to just toss in my bag for a fun game of multiplication or division review on the go. The only card that we’ve come across that seems to yield some questioning as to its usefulness is the card that has two zeros and a 1. 1x0 equals 0. And 0 divided by 1 equals 0. But 0 divided by 0 isn’t 1. It’s undefined. If you stick that problem into a calculator, you will get an error. So other than that one card, this set is great! Still worth the 5 stars because of the great sizing of the cards and reusable packaging that makes it easy to take with you on trips and car rides.

We do like these and they are simple to use however I don’t find them as easy to hold and cover the answer as I thought they would be. Based on the design and idea I thought they would be easy to use and cover the answer with one hand. They aren’t that simple and that’s fine. They serve the purpose. I think we prefer just regular flash cards.

These are so handy because the can be used for both multiplication and division. Depending on which number you cover, they are actually 2 problems on one side ( or 4). Go through the stack, setting aside which ones the child hasn't mastered then flip them over to do opposite side.

Good quality and easy to use.

Not only is this an excellent product, the customer service is AMAZING! I had several questions that the owner personally addressed. As a 5am runner (in a town that isn’t big on street lights or sidewalks) I needed something that made the world less pitch black-ish. Without Knuckle Lights, I would not be able to run in my area. I love that they are bright enough to stop someone or something from coming directly toward you (my runner friends are not a fan of when I talk with my hands while wearing them bc they are BRIGHT) but they are lightweight, shine a wide path ahead, and are easy to carry. Fabulous excellent amazing product. Just buy them.

The NOTCH at the bottom, which no other brand has, make these three-corner flash cards the quickest, easiest cards for anyone to use. When these cards are dropped, because of the notch, it takes no time at all to gather them into a pile that is ready to use. Also, the colors are really bold and bright. The products are one color and the factors another color. As a classroom teacher, I have tried cheaper brands and even making my own, but no longer. TREND’s Three-Corner Flash Cards are the best way to help students learn their facts. Children can use these alone, in pairs, or in groups. I even show my parents how to use these cards so they can them at home. Oh, and MY STUDENTS LOVE THESE CARDS!!!!! They are so excited when their parents, or Santa, gets them a set for home.

MUY BUENO!!!!!! sirve desde las primeras tablas y a manera de juego entre padres e hijos, tutores o maestros y alumnos. Creo una herramienta excelente para escuelas y la casa. Lo recomiendo!

I like that the cards have both multiplication and division on each side, it reinforces the connection between the two operations.
