Parents and educators appreciate how this magnetic marble run makes teaching fundamental STEM concepts intuitive and engaging, allowing curious minds to explore the world around them through hands-on experimentation. For ages 5+ Review: Wonderful Toy - All of the other marble tracks I purchased in the past were disasters. Being magnetic, obviously the process of assembling and disassembling is hassle free. I love this product. It's rare to find a fun, educational toy that gets played with more than once. I bought this quite a while ago and it is still popular in my home. It's a good value and would make a wonderful gift. Review: Totally Worth It - This is a pretty great toy set. It’s imaginative and fun as well as inventive. All our kids ages 2-7 like playing with it. They love to race the marbles down the tracks and will do so for a long time. It comes with a set of laminated cards you can use for inspiration. Our youngest liked these a lot and I was surprised how well they could follow the card to make a track. It made it a toy they could use without me!! Though we use it a great deal together. The pieces are light but sturdy made of foam and have taken significant use and are holding up well. Since we use them on a chalk board they have been cleaned a bit too and they still look great after being covered in colored chalk. The magnets are strong and the pieces hold well, but not ridiculously so. Making rearranging or removing easy. The marbles that come with it are a bit lighter than the standard run of the mill kind so work best with the set. But regular ones work well too (since we seem to lose the given ones from time to time). It’s when you build a track that gets going fast and the force of the stop makes the basket piece fall off. But who can get mad at that? The tracks can go pretty fast. ## Features - CREATIVITY BOOSTER - Encourages young engineers ages 5+ to design, test, and problem-solve as they create fun marble runs on any magnetic surface, developing critical thinking skills through play - EDUCATIONAL ENTERTAINMENT - Keeps children engaged for hours while secretly teaching STEM concepts like gravity, momentum, and cause-effect relationships through hands-on experimentation - VERSATILE PLAY - Works perfectly on refrigerators, magnetic whiteboards, oil drip pans, or any magnetic surface, making it ideal for homes, classrooms, or therapy settings with multiple setup options - COMPLETE STARTER SET - Includes 14 colorful magnetic foam track pieces, 4 marbles, goal basket, and 10 activity cards with pre-designed challenges to inspire countless creative combinations - DURABLE DESIGN - Features sturdy foam pieces with strong magnets that stay firmly in place during marble runs yet remain easy for small hands to reposition when creating new paths and challenges - 0 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00S2XPFVQ | | Age Range Description | Kid | | Best Sellers Rank | #15,144 in Toys & Games ( See Top 100 in Toys & Games ) #15 in Marble Runs | | Brand Name | Learning Resources | | Customer Reviews | 4.6 4.6 out of 5 stars (1,434) | | Educational Objective | stem | | Global Trade Identification Number | 00765023028218 | | Included Components | Counter toys | | Item Dimensions | 12.75 x 10.25 x 2.75 inches | | Item Type Name | Tumble Trax Magnetic Marble Run | | Item Weight | 22.68 g | | Manufacturer | Learning Resources | | Manufacturer Maximum Age (MONTHS) | 120.0 | | Manufacturer Minimum Age (MONTHS) | 60.0 | | Manufacturer Part Number | LER2821 | | Manufacturer Warranty Description | No Warranty | | Material Type | Foam, Metal | | Model Number | LER2821 | | Size | 10.25 inches x 12.75 inches x 2.75 inches | | Sub Brand | Learning Resources | | Theme | Buildings | | UPC | 765023028218 | | Unit Count | 1.0 Count | ## Images ![Tumble Trax Magnetic Marble Run - STEM Toys, Marble Runs for Kids 4-8, Marbles for Kids, Gravity Maze, Marbles Game, Ball Maze Toy, STEM Magnetic Track Toy - Image 1](https://m.media-amazon.com/images/I/81JV2XydICL.jpg) ## Available Options This product comes in different **Pattern** options. ## Questions & Answers **Q: How thick is the foam to keep the marbles from falling off or is there a lip that I can't see from the pictures?** A: The foam is very thick ~1in? and there is clear plastic guard attached to each piece that keeps the marbles from falling off. Really fun, although pieces are bigger than the pics suggest and it takes up my whole bottom of my fridge. Kids had 2 hrs of fun playing together Xmas morning! **Q: Which of these size magnetic boards work... 3×4, 3×5 feet?** A: 3 x 4 is good **Q: Will 2 ft ×3 ft metal board be too limiting? We don't currently have a magnetic fridge.** A: Yes. That is too small a space I use my metal door. My daycare kids of all ages play with magnets. From 3 to 12 one of the best toys ever **Q: does it have enough pieces for 5-6 kids (5 year olds) to play at the same time?** A: Not really. I think it would work maybe up to 4 if the magnetic board is large enough for the students to have room to use the parts. I used with 4-year- old's and I only let 2 students use it at a time. It also does not hold up. My students wore it out the first year. The class I used it with, knew how to use it and took care of it. They liked it and used it a lot. I was hoping to have it longer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Wonderful Toy *by 6***0 on August 22, 2025* All of the other marble tracks I purchased in the past were disasters.

She needed some help to get started with how it needs to go for the balls to make it to the little box but after she was shown how it works she had it. Great toy to keep kids her age busy but keep away from smaller kids because of the little balls that come with it could be a choking hazard for little ones that like to put things in their mouth. ## Frequently Bought Together - Learning Resources Tumble Trax Magnetic Marble Run, STEM Toy, 28 Piece Set, Ages 5+ - Learning Resources STEM Explorers -Ages 5+, Magnet Movers, Critical Thinking Skills, STEM Certified Toys, Magnets Kids,Magnet Set,Back to School Supplies,39 Pieces --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/14296069-tumble-trax-magnetic-marble-run-stem-toys-marble-runs-kids](https://www.desertcart.vu/products/14296069-tumble-trax-magnetic-marble-run-stem-toys-marble-runs-kids) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
