This learning resource focuses on the foundations of meaning by exploring prefixes and roots, specifically the prefixes (un-, re-, pre-, dis-) and roots (port, vis). The objective is to help students understand these word parts and accurately match them to their definitions with an 80% success rate. The document includes activities that promote collaborative learning and mastery through matching exercises. It also provides a challenge extension that encourages students to think creatively about language by forming new words from the learned prefixes and roots. The resource is designed for educators to assess student understanding and confidence in their language skills.
