As students build their own tables, find two different ways that the students are expressing their ideas and ask the students if they would be willing to share their work with the class.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. As students share their work, ask another student in the classroom to compare what they heard. For example: \u201cCan someone say how William\u2019s and Jacob\u2019s tables are different?
