The Learning Resources Nestable Bucket Balances are a fantastic way for young learners to explore basic mathematical and scientific concepts. This set of 4 balance scales allows children to investigate weight, volume, and equivalency using clear, 500ml plastic buckets that hold solids or liquids. The scales are designed to introduce key math concepts such as inequalities, mass comparison, and operations like counting, adding, and subtracting. The equivalency dial helps students understand concepts like greater than, less than, and equal to as they experiment with balancing different items. Easy to assemble and disassemble in just two steps, the scales also nest together for compact storage, making them perfect for classrooms and homes. The set includes 4 balance scales, 8 buckets, and a convenient storage base with handles. Ideal for children ages 3+, this set encourages hands-on learning and supports early math education.
