What activity would best reinforce the reading and spelling of multisyllabic words with -es, -ed, -ves, and -s endings?

Finding examples of words with the specified suffixes within texts and reading them is the best activity for reinforcing the reading and spelling of multisyllabic words with endings like -es, -ed, -ves, and -s. By actively locating these words in context, students not only practice their recognition but also begin to understand how these suffixes function within different words. This contextual learning enhances their spelling abilities as they see the words in action and can better grasp the pronunciation and syllable structures associated with them.

Through this activity, students can develop their morphological awareness, which is crucial for decoding and encoding complex vocabulary. It allows them to examine how suffixes alter meaning and grammatical function, thus deepening their overall language comprehension.
