Reflection: Student Ownership Debate: Does This Shape Show Fourths? (Day 1 & Day 2) - Section 1: Warm-Up


During this lesson, my entire class was convinced the shape did not show halves.  Each one of their responses held the position of no. Having the students take ownership of their position was accomplished through a journal entry to explain their position. I wanted to understand in more detail about why it did not show equal fourths in their math journals.  I wanted to review their thinking and analyze if they were looking at the shape as two squares and two triangles, two rectangles, or one large square.

Their thinking revealed they were viewing the shape as two squares and two triangles, and this indicated to me they are lacking in understanding the relationship between geometric shapes.
