Based on their peers’ and the first author’s comments and suggestions, the Lesson Study group revised their GSP sketches accordingly by referring to the above GSP books as well as seeking help and guidance from the first author. As a result, they successfully constructed the teacher and student versions of the GSP sketches as shown in Figure 7 and Figure 8 respectively. Further, they also were able to combine the eleven GSP files into one single file by using the File menu and the command to create multiple pages in a single file as shown in Figures 7 and 8.
