LEARNING RESOURCES VIEW-THRU GEOMETRIC SOLIDS (14-COLORED)

I think they are slightly fragile. They are not toys, and cannot withstand that type of use, for sure. But! As a learning/teaching aid, these things are super cool! They are see through and have an opening, with plug, to fill each shape with water, and demonstrate the concept of volume! I liked them as an introduction into shapes, and when I got them, I saw that they were to teach all about volume too! By far, one of the coolest little sets to have in your classroom/homeschool. They could stand to be a little more sturdy, and durable. I'm afraid to drop them. Also, should come with a graduated cylinder, for filing the shapes, and precise measuring. Needed em for science anyway, so I had to grab a pack of those.

Great math manipulative for homeschooling!

These are great. I've read people reviewing saying that theirs were falling apart out of the box and all I can think is they got a defective product. I bought two boxes and all of the shapes are fine. Most of the shapes have three pieces: the small, removable piece covering a hole (for filling) and then the removable side piece (for easier filling and cleaning) and finally the rest of the shape. They are all solid, but you are not paying for shatter resistant pieces of acrylic. This item would cost much more if you were. They are simply shapes made of thin, but not too thin Plexiglas. Obviously, if they are in cold conditions for a while the plastic will deteriorate in strength and may crumple, but otherwise these are sturdy enough.

My son, who loved mathematics and was learning 3D shapes, was excited and got what he wanted. He started to draw 3D shapes in a week, Shapes also were fun to play in the bath, and boys used them for other buildings. However, as always with all those small plastic toys, they were broken and half way lost parts. There is a small circle detail that is easily reattached, my boys were able to poor water because of the detail, but it can be dangerous for small babies.

👍

These are so cool! They have a cap that comes off, so you can fill it with water, sand, or rice. We have used these in our multi-aged homeschool class for 3 years. Great quality.

My children loves this resource. Makes learning 3D shapes easier with this concrete sample. Be careful though, this is delicate, can crack easily when it accidentally falls to the floor.

This is a perfect hands-on manipulative if you teach any element of geometry. Sometimes it helps students to see exactly what you're referring to in 3D. 1/1/12: I'm editing my review now that I've used these more in my class. Since I teach a state testing grade, my students have to know how to do geometry on paper and not just by using manipulatives. This product really helps me bridge that gap. I introduce the concept with these then I move on to counting edges and faces, etc on paper. When my students struggle with the paper portion of it, we go back to these and I let them hold it while counting. Then we refer back to the paper. These have been a life saver in my small groups. I'm not sure if the product description says it, but these have small clear holes that are plugged. The little plugs fall out very easily (con), but the whole point of the holes is to use them to fill and teach volume (pro!). When I first bought these, I intended to use them only for faces, edges, vertices. Now I intend to use them to teach volume, too. I can't say enough good about Learning Resources ans their products.

※細かいパーツが多いので小さいお子さんの場合は先に大人が隠すなどする必要あり！ 年長の息子が喜んで遊んでくれてます！ 最初に、これは円で、これは円柱で～と説明したら、これは何の形～？と聞いてくれるようになりました！ これは期待！

Bought these for play with sensory consideration as they look great with a light box I made...colours very vibrant and helps extend learning opportunities

I was facing difficulty in educating my little ones in understanding edges, faces and vertices of 3D shapes. This simplified my work.

حلوة اشتريتهم لبنتي عشان أذاكر لها درس المجسمات ، بس عيبها القاعدة منفصلة عن كل مجسم ،لازم نحافظ عليهم ونرفعهم عن الأطفال أول مانخلص عشان مايضيعون ومايحطوهم الصغار بفمهم .

Great quality shapes. My son loves to build with them as we name each shape. These have helped him better identify different shapes in preparation for school.
