Another good right hand assignment idea is the use of webs. In the picture above we were talking about the five characteristics that all animals share. I instructed the students to create a web using words and pictures addressing all five characteristics. (The left hand assignment students had to answer a series of questions from their text addressing those five characteristics).
If you need to differentiate instruction the web can be done as a group on the board. You can ask for volunteers to give you the words and have folks come up and draw the pictures. Students then copy it into their book. To differentiate a textbook search list the page number the student can find the information and make sure that all questions are in order of how the student will find it in the textbook.
