There is a lot of dialogue in this book and therefore many punctuation marks are used. The correct use of quotation marks is especially difficult to master. Here's an activity to help the students understand how to use punctuation marks:
dark color felt tip marker
blank sentence strips
light colored construction paper( you may even choose to color code the punctuation marks,ie. yellow paper is for a period, green paper is for quotation marks,etc.)
Write some sentences(without any punctuation) on the sentence strips. Use some of the dialogue from the book.
Use construction paper to draw quotation marks, periods, questions marks and commas on individual papers.
Instruct one student to hold a sentence card up facing the rest of the class. Call on individual students to hold up a punctuation card in the correct places until the work is complete. The physical act of doing it, helps the children retain the concept at this age.
You may choose to lay the sentence on a table or on the floor in front of a reading group and do the same activity with a smaller number of students. Repeat this several times with different sentences.
Keep the cards stored together to pull out when you are working on punctuation again.
