The animals are colour coded helping develop colour recognition for your little one. Easy to build and connect the magnets, your little one can also get creative and create crazy combos of farm animals. The animals are soft, and the pieces are extra large so that they cannot be swallowed. Compatible with all other SmartMax sets this STEM construction toy is perfect for teaching your little one names of the safari animals, colours and plenty of skills, all whilst having fun! I bought these SmartMac xl and then the Hauker 88 piece set for 33.99 alot tcheaper and over 2x the pieces and a tote. Im not good imagining dimensions and wanted big pieces, so i bought both. SmartMax My First Farm Animals is designed for young children between the ages of 1-5 years offering an early, safe, fun and educational introduction to magnetic discovery.
