In this 5th-grade lesson, students will decode and analyze unusual plural forms in English. They will explore how inflections like -s and -es are used to create plurals. The lesson highlights specific rules such as how -es forms its own syllable when following a consonant, changes with -y, and the transformation of -f to -v. Students will engage in syllable division, read aloud examples like 'cricket/crickets' and 'mystery/mysteries,' and participate in independent practice by finding additional plural words in their texts.
