Perfect for all those budding palaeontologists, this set of durable dinosaur bones and activity cards is guaranteed to engage young learners. Cast from a durable and unique mix, the bones can be used in sand, soil or even water, instantly appealing to children's instincts to explore, investigate, collect, compare and measure. The bones increase in size by 2cm and are ideal to introduce the concept and language of measurement, doubling and halving. Each set includes 16 bones, two of each size: 6, 8, 10, 12, 14, 16, 18 and 20cm. The activity cards extend the learning possibilities, encouraging children to match, count, compare, order and measure the bones they discover. Made from durable PVC, the cards are tough enough to use in the outdoor area (including water play). Each set includes 16 colourful plastic cards measuring 275 x 210mm. Age Suitability: 3 Years +
