The set consists of eight themed Creative Cards designed to extend the use of the Creative Builder set. The cards feature 16 building challenges designed to help children learn how to build and to follow instructions. This set is great for developing collaboration between children, and for encouraging them to use descriptive language. It helps children to develop an understanding of the wider world, and particularly of roles and emotions that relate to community. All the building challenges in this set can be completed using the elements included in the 9090 XL LEGO® DUPLO® Brick set + the 45000 Creative Builder set.
