Think2Master Subtraction Flash Cards. Learn to Add & Subtract by Counting, Writing, Understanding & Memorizing. 260 Laminated Cards, 39 Triangle Cards, 2 Dry Erase Markers, 5 Rings & 30 Counters

I have been looking for something like these for weeks, so forgive me for the length of this review.My first obstacle was to find cards that have a single problem per card. If my child is having trouble with one specific equation, why would I want to have another equation in the mix on the other side of the card? If the cards get flipped or shuffled, then nobody knows what problem we are really focusing on! And then if there actually is a card where you are trying to practice front and back in a pile of cards where you are only practicing the front card, well that's just frustrating. These are perfect. One problem, one card.I also like that the back has dots to help understand how we got the answer. This is how I was able to "connect the dots" for my child before buying these cards. When practicing, we would do dots, then circle the dots into groups. This has it done for us so we don't have to draw our own anymore!Plus number three- these can be written on with an erasable marker. They feel more like plastic than cardboard or paper. These will hold up to using wipe board spray for those times when you write so much it leaves that hint of color from previous use (you know...where the kids still see the answer from last time and they get mad that you cleaned up their ability to cheat. Lol).Plus number four- holes for rings. Keep all the ones they need to practice in one place without them sliding and falling all over.Plus number five- I was a little unsure about these "triangle cards." Maybe I'm old, but I've never heard of such a thing. I kept searching for division cards and these kept coming up. So what the heck, I went with this set with triangle cards. I showed them to my child and she instantly understood what they were showing. We teach our kids in compartments (only doing multiplication with one number as a focus), so I think these will be great for helping her understand the connection between multiplication and division.I'm very happy with these and am confident they will last for both my kids to use, which is a great deal for the quality!

Product is amazing and very helpful for learning.

This has helped my daughter tremendously with her 4th grade math!

It definitely helped my son with his multiplication.They are sturdy and can be written on.

Nice flash card set for adding, subtracting, multiplying, and dividing. Has rings they are on but can be removed from if you use individually.

My daughter has been struggling for years with her math fluency. It's not really worked on in schools these days, it's expected to be practiced at home. We have done all sorts of DIY aids and when I searched out this product, I was hopeful. We were not disappointed! Finally!!! It was not a struggle to get her to use this tidy little set and we both enjoyed the "tricks" for different facts that were new to us. She is still practicing but I have finally seen a break-thru. You would not be disappointed in the investment and the cards are good quality and the box is sturdy. THANK YOU!Math Mom Homeschooling!

Regular home made flash cards were boring. The kid actually likes these and is much more enthused about practicing. Really like the dry erase pens so he can factor on the card

I have two kids and purchased this cards because I wanted to introduce them the basic concepts of math easily.I think these cards are a great way to build the proper foundation of math for my kids. Each of these flash cards are well organized and it allows the kids to discover the hidden patterns of addition, subtraction and multiplication before letting them also memorize it. The counters also aids in learning addition and subtraction and the triangle cards can also be used for learning division.Also Dry erase markers and the fact that all the cards are laminated makes them handy and ensures that they will last a long time.My kids have so much fun using these cards. They love them a lot!
