One component of the ELA program is vocabulary. This introduces them to compound words, multi-syllable words, homophones, synonyms, and many more vocabulary subjects. He tends not to like doing them as it gets repetitive during the unit and he usually grasps the items after only two lessons. However, this subject is totally computer based and he does like some of the activities it uses.
When possible, we use library books or youtube videos to supplement as well as what I might find on Teachers Pay Teachers.
Again, we used two series that we both like. We used the series for nouns, verbs, and pronouns already. The illustrations and rhymes help focus on the subject making it easy to grasp quickly.
