Learning ResourcesMathLink Cubes - Set of 100 Cubes, Ages 5+ Kindergarten, STEM Activities, Math Manipulatives, Homeschool Supplies, Teacher Supplies

Our son is 4 and has so much fun with these. He recognizes the number blocks by color (from the show Numberblocks) and can add, subtract, and multiply pretty quickly by looking at them. This is also a great alternative to legos. He builds a lot of different things with these. They’re durable, easily taken apart and put together, and the shape and size of it doesn’t hurt when you accidentally step on them lol. Great product. We have asked friends and family to buy these as gifts for birthdays and Christmas because we feel the possibilities are endless for our children. The more they have the more they can build and learn!

Loved them purchased for math class and quality was great bright color size was just right . Functional was good . Durability great storage space perfect placed them a box and keep safe . No missing pieces. Very easy to use . Value of money can't complain.

Well built, very versatile tool for teaching math. I'm a homeschooling mom with a PhD in Molecular Biology. Math is one of the most fundamental skills that I want to give my kid. At first, I was using duplo blocks to illustrate addition and subtraction, and I didn't see why I might need anything more. Then I found these Mathlink cubes. They turned out to be the single best math learning tool I've used so far.They are well constructed, snap together well, stay together well, and come apart easily for me (slightly difficult for my 5 year old to assemble, but she can pull them apart easily). You can actually build three dimensional shapes with them (you have to be a little clever about how you rotate each block, but it works). My 5 year old and I might construct a 3 X 3 X 3 cube and talk about why 27 is a cube number, while the the 3 year old uses the cubes to build a "crane" that is 30 blocks high. We use them in place of cuisenaire counting rods. We use them to illustrate concepts in our Singapore Math work book. We use them to illustrate multiplication. We use them for place value (10's and 1's), subtraction with borrowing, etc.They come in a set of 100, with 10 of each color. For the homeschoolers, I'd recommend buying at least 5 sets of 100. You really need to have about 50 in one color in order to really use this learning tool to its maximum potential. The only downside of these blocks is how many you need to buy to really use them.Also, note, on each six sided cube, there are 5 "holes" and only one "nubbin" that sticks out. At first, I was wishing there were two "nubbin" sides, to make it easier to build stable 3-D shapes. But after months of using them daily, I've concluded that the 5/1 design gives the toy the most flexibility for math teaching.Are they a choking hazard? Yes. Can they be chewed up by a toddler? Yes.How will they hold up after years of use? I don't know. Judging by the slightly rubbery plastic material they are made of, they will probably last a few years with intense use. So these are not quite as durable (or precision engineered) as Lego/Duplo products, which will last for generations. But still, excellent value.

My 5 Year old son is on the spectrum and he absolutely loves using these blocks to build and engineer his Letters and Numbers even though they’re intended use is for math. These blocks have really helped with his hand and eye coordination. The multiple color variation is also one of my favorite features. I will continue to purchase this product and the great thing about it is that they are useful even as he gets older!!

Great for fun and learning.You can do SO much with them!Highly recommend.

These are colorful, well made, well finished, fit together well, and the price makes them no real risk. They are quite lightweight, so they can get top heavy easily if placed vertically, they only snap together on one end of each cube and sometimes can take patience to unsnap. I plan to offer them for fidget purposes for kids in psychotherapy.

When I ordered these, I didn't know how awesome they actually were. My sons build all kinds of Minecraft structures, dinosaurs pixel style, etc. They work great for math too, but the ability to build with them is the best feature.

I bought these from my son for school so I wouldn't have to use the school supplies. They're great quality.They stick together so you don't have to worry about them falling apart.They come 10 in a color
