We received a comment from a teacher that her students were having a hard time grasping the concept of prepositions: what they are and how they are used. Sounds like a topic for which images and hands-on activities will help turn on those mental lights!
In order to become stellar readers, children need practice finding prepositional phrases in text. One reason for this is to help them read more fluently. Think about the phrasing fluent readers practice that make their reading fluid and easy to understand.
For the sake of this post, I am using 12 words, but in my classroom, the walls were full of words. We had a word wall which was arranged in ABC order in columns and then we had a wall devoted to our big words grouped by part of speech: nouns, verbs, and adjectives.
