I have used the cards teaching K-6 all grades. There are 3 different levels of challenge cards, appropriate for any age. This set is well worth the price. The cards are high quality and have lasted for years of use by lots of kiddos. The carrying case is super handy for home use and for keeping up with the cards at school. If you want to use for a whole class, you will want the KEVA planks 200 pack and this brain builders set. Bundle the 200 piece set into groups of 20 and rubber band them. Then you will have plenty of sets for each group in your classroom. I start everyone on beginner level and make them work their way up to intermediate and then expert. This really is a fun set that is easy enough for 5 year olds and challenging enough for 6th graders. Review: These are great in my classroom. I use them in morning STEM tubs. ## Features - Build structures to match the blueprint challenge cards! - Train your mind to think in different dimensions as you create 2D challenges in 3D. - Varying difficulty levels. - Includes 20 KEVA planks and 40 puzzles in a zip-up carrying case. - Suitable for 1 or more players, aged 4+ ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00UUA8BDS | | Assembly Required | No | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 452,462 in Toys & Games ( See Top 100 in Toys & Games ) 10,336 in Board Games (Toys & Games) | | Colour | Multi-coloured | | Customer Reviews | 4.5 4.5 out of 5 stars (164) | | Date First Available | 16 April 2015 | | Educational Objective(s) | Awareness, Concentration, Numeracy & Literacy, Recognition | | Item model number | 68337 | | Language | English | | Manufacturer recommended age | 4 years and up | | Material Composition | 100% wood | | Material Type(s) | Wood | | Number of Game Players | 1 | | Number of pieces | 60 | | Product Dimensions | 38.1 x 40.64 x 7.62 cm; 280 g | | Remote Control Included? | No | | tech_spec_battery_description_toys | No batteries required | ## Images ![Mindware | KEVA: Brain Builders Junior | Children's Brainteaser | Ages 4+ | 1+ Players - Image 1](https://m.media-amazon.com/images/I/81ZeaNjtTPL.jpg) ## Questions & Answers **Q: How is Brain Builders different from loose KEVA planks?** A: It pairs 20 standard planks with double-sided challenge cards that ask players to turn 2-D diagrams into 3-D builds—turning construction into a brain-twisting puzzle. **Q: Exactly what comes in the case?** A: 20 KEVA maple planks, 30 illustrated puzzle cards, and a zippered carrying case. **Q: Who is it intended for?** A: It’s recommended for budding engineers age 7 and up. **Q: What skills does it develop?** A: Solving the cards sharpens spatial reasoning, engineering mindset, fine motor control, and perseverance. **Q: Is it travel-friendly?** A: Absolutely—the compact zip case keeps planks and cards organized for classrooms or road trips. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***D on 20 August 2025* I’m a teacher and use this at work and at home with my 5 year old.
