This set of hard paper classification cards (SKU: G232) includes both Set 1 and Set 2 of the Land and Water Form series, offering a durable and cost-effective option for teachers who already have the physical trays and need the card component for matching and nomenclature work. The hard paper stock holds up to regular primary classroom handling better than standard card stock, making it a practical choice for high-traffic shelves. Having both sets together allows teachers to present a full continuum of landform concepts without sourcing cards separately.
