This CARGO CONNECTSM Teacher Guide aims to support Irish primary school teachers by illustrating how FIRST® LEGO® League Explore CARGO CONNECTSM (hereafter referred to as CARGO CONNECTSM) aligns with the Irish Primary School Curriculum. Through engaging with the CARGO CONNECTSM challenges, learners investigate how cargo is transported, sorted and delivered to its destinations; rethink how cargo could be transported from place to place; and propose creative solutions relating to the future of transportation. Grappling with this authentic real-world issue, learners develop a range of knowledge and skills as they learn to design, build and code, in order to create unique solutions made with LEGO® elements and powered by the LEGO® Education WeDo 2.0 or SPIKE™ Essential set.
