Cast from a durable and unique mix, these bones are just waiting to be discovered. Bury them in sand, soil or even water, and they will instantly appeal to children's instincts to explore, investigate, collect, compare and measure. Perfect for all those budding palaeontologists! Each bone increases in size by 20mm and can be used to introduce the concept of measurement, doubling and halving. Children will love to discuss their discoveries so this set provides the perfect opportunity to develop and practice the descriptive language of measurement e. g. longer/shorter. Use the dinosaur bones alongside the Activity Cards (Code 244988). The set includes 16 bones, two of each size 60, 80, 100, 120, 140, 160, 180 and 200mm.
