Students come to the carpet with their whiteboards and markers and we review reading and writing number words: Number Word Mini Lesson.
The first part of this practice is a review of (mini informal formative) number words. Students may work with a partner on this. I monitor them to see if there is a child in a partnership that doesn't understand and I record that information in my anecdotal notes.
Then, students work with a partner and read and analyze the word problems, looking for the pertinent information and setting up the addition and subtraction problem. I walk around to prompt them to talk about what they are doing in complete sentences.
