Interlocking is the way to go

I was hesitant to go with the interlocking blocks because of the comments that they were challenging to squeeze together and take apart for small hands. I didn't have a reason to worry. My 5 year old girl didn't have any trouble, and when it comes to grouping, the interlocking is the way to go! We are happy with this purchase.

These are fantastic! I let my son play with them for about an hour when we first got them just so he could get familiarized with them and he loved it. I love them because they are great quality for the price. They came in perfect condition no chips bends or dings. They interlock together ok. I wish they snapped on a little bit "sngggier" but it's not really a big deal for me they snap on and that's good enough. My only real wish is that the thousand cube was weighted just for clarification purposes. Other than that these are perfect. All the different values come individually packaged in zip lock bags tucked in a plastic tub with a lid. This makes putting them away super easy. Just keep the plastic zip lock bags to store them and they all fit back in perfectly and easily. I'm very happy with my purchase and Amazon Prime allowed me to get them in 2 days🤗🤗 What's included: 1 One Thousand Cube 10 Flat trays (the hundreds) 50 Rods (the tens) 100 small singles (the ones)

Bace ten Blocks

works well. A little hard to pull apart, but manageable. My 6 y/o loves playing with them also, building hings then telling me how many blocks she has used.

Affordable, simple, well made manipulative.

These manipulative base ten blocks are extremely helpful in working through larger math problems or visualizing word problems. We bought them to use when my son began addition and was struggling to understand carrying to a new place value. They helped him to visualize what was happening as he counted and began addition. The blocks are very simple and sturdy. They are not fancy but when working with math, you don't need fancy and distracting. The "ones" are very small so they should not be used for small children. There is a large block to represent 1000 but it is nice that there are also 10 sheets of 100 so that you can create another 1000 block or add to it. Gives more dimension to what is in 1000 than just the empty large block. Overall, great and affordable manipulative for the parent, teacher, or home-schooler when you want something visual to aid in problems.

Great set of Base Ten Blocks.....one of the best out there for the price.

This really is an awesome set. The pieces fit and stay together perfectly. Price on this set is fantastic! It is a very large set and some great number combinations can be made with it. There are enough 100 blocks to easily build a additional 1000 unit cube. This is great when your numbers jump up to 2000. We got this set for you our 1st grader and preschooler. Our first grader was having issues when sums over 1000 resulted in the 100's place having a "0" (ex 980 + 80). This set has help give him a better visual reference for these numbers and there place values. Another review provided 3 stars based on the container. The quality of the container can be better, but this is a non-issue. The blocks can be put in a a Ziploc bag and you would still have a quality set of base ten blocks that will help your children learn some essential math skills.

Why isn't this already in your class inventory??

Great set of base ten cubes!! It even comes with a bonus booklet that comes packed with chock full of ideas and activities for young learners. A must for any classroom...

Indispensable tool to ensure conceptualization of regrouping, place value, and geometry, K-6. Very helpful activity book!

Bought these after considering traditional base ten blocks and found the ability to compose and decompose units to ten rods and back again, and similarly stack ten rods together to form a hundred flat (or break it down again to rods) something we wanted for teaching regrouping according to place value, both for addition/subtraction, and multiplication/division. These interlockable blocks are also great for teaching surface area and volume and fractions, decimals, and percents. Kudos for Amazon's customer service also: our order came without the book, but an online chat with a representative resolved the issue nicely. The activity book has many of the same activities from the ETA Cuisenaire Super Source books, but in a more condensed form with instructions for use that are more concise and easy to apply. The activity book includes blackline masters for activities, and each lesson has a description for the teacher on the left page along with standards covered and materials list, and the reproducible activity sheet to hand out to students, on the right. It also organizes activities by the grade ranges of K-2, 3-4, and 5-6, which means the set is useful for many different ages and stays useful for many years. As to the quality of the blocks, and I was concerned after reading reviews, but my blocks are well-made, seem sturdy and precisely molded, and the individual units are a cubic centimeter. They can go together either loosely or tightly, but I recommend attaching them loosely when joining them together, to make them easier to separate again. The hundreds flats do come snapped together quite tightly to form a second perfect thousand cub, and a Lego separator or other thin, flat, rigid device may help pry them apart that first time. Thereafter, I don't attach them perfectly, but loosely, so as to avoid that problem when taking them apart. The thousand cube that is not made of hundred flats, seems molded in one piece (there was no removable lid as one customer showed, so the manufacturing seems to have improved) and quite sturdy, and reasonably heavy though not as heavy as the cube that can be made from hundreds flats. As others have warned, these don't have rounded corners. They appear molded precisely and with very square, sharp corners, so dropping one on a bare foot would probably hurt. Some have mentioned it being difficult to put the set back in the storage tub, but I didn't find it hard, so long as you arrange the tens rods with the same endwise orientation they arrived in, and keep the thousand block in the center of the lid. I keep my unit cubes and tens rods in the same small ziplock baggies they came in, for ease of keeping track of them and packing them away in the storage tub. My tub's lid was clear, not blue as shown. But it works. I really like how this set teaches the teacher, quickly and clearly, by describing the activities briefly and then getting on with it. A good textbook or curriculum that features using base ten blocks to demonstrate the physical reality of the regrouping algorithm (what some call "carrying" or "borrowing" but that is more accurately called "composing and decomposing higher and lower orders of value" by Liping Ma) in both multiplication/division, and in addition/subtraction, will also pair nicely with these.

Love that they fit together

This has been a great resource for our home school math. These link together much like legos. They are easy to take apart and are sturdy. The book that comes with the set is full of helpful games. The box is not stellar. Ours broke, but it is an easy replacement.

Kids loved them!!!

I gave these to my grandchildren as a gift and they loved them!!! They play and build different things with them all the time. They come in their own storage box which keeps them nice and neat too (which their mom appreciates). Just be aware there are some small pieces so they are not for everyone.

I Love these interlocking base 10 blocks

I Love these interlocking base 10 blocks! It really comes in handy when I'm teaching my kids how to add/subtract numbers (ESPECIALLY with regrouping/borrowing), they can physically build their problems.
