Dictionary skills are big in 3rd grade! My students always seem to struggle with guide words...they are TOUGH for them. By giving them a word of the day, they practice their dictionary skills while also expanding their vocabulary and spelling skills.
What I do is make a book using large construction paper...12X18. I fold it in half and put a cover on it and then laminate it to keep it durable. I have insertable sheets that I copy front/back and staple in to into the booklet.
I give my students a word of the day each morning. The students write the word (spelled correctly of course), write the definition, use the word in a sentence, and write the guide words.
This can be use in addition to any morning work that you already use.
You could differentiate by giving different groups of children different words.
